Our May 2023 Comments on the Route 28 Bypass Project

On April 19 and 20, 2023, the Prince William County Department of Transportation held a pair of public information meetings to present the status of its Route 28 Bypass project at roughly the 30% design stage.  In response to the information presented, Active Prince William submitted the following written comments on May 3, 2023.


Please consider these comments on the Route 28 Bypass, based on information that was presented at the April 19 and 20 Route 28 Bypass Project Public Information Meetings:

Traffic and Environmental Studies, Sustainability, and Cost Comments

The ongoing traffic forecast and environmental studies for the Bypass should report relevant data that will help the public, the Prince William Board of County Supervisors, environmental oversight agencies, and other stakeholders determine whether building this highway project would be a prudent investment for both our region and for Prince William County taxpayers.

 1.  Please report the additional Vehicle Miles Traveled (VMT) and Greenhouse Gas (GHG) emissions this project would generate vs. the no-build alternative.

Justification:  The information will help the PWC BOCS make an informed decision about the project as it weighs competing priorities about the environment and sustainability, including consistency with Visualize 2050’s policies and the objectives of the County’s own Community Energy and Sustainability Master Plan.

2.  Please report the additional noise and air pollution this project would generate within ½ mile of the corridor vs. the no-build alternative.

Justification:  Understanding the full impacts on nearby property owners within an Equity Emphasis Area that would lack direct access to the roadway facility is paramount for PWC BOCS to make strategic future decisions about this project vs. other priorities.

3.  Please report the residency locations of the projected Route 28 Bypass users; in particular, what percentage of projected highway users would reside in a) Prince William County, b) the City of Manassas, c) localities west or south of Prince William County, and d) localities north or east of Prince William County?

Justification:  With 90%+ of the cost of the project being funded by PWC taxpayers via NVTA and the 2019 Mobility Bond, this is useful information to help the PWC BOCS make strategic future decisions about this project vs. other priorities.

4.  Please report an updated project cost estimate based on the 30% design.

Justification:  With highway construction costs increasing by 50% in the past two years, it is difficult for stakeholders to understand the viability of a 2019 $300M cost estimate as the PWC BOCS plans to invest significant taxpayer $$$ into the project soon.

Shared Use Path/Trail Comments

If located in most other suburban communities, the Flat Branch stream valley would have been developed–decades ago–as a linear regional park, with non-motorized access serving and unifying the communities on either side.  Because the County has long reserved this corridor for a potential future freeway, the development of such a stream valley park has been delayed for decades.  Construction of the Bypass would establish a permanent man-made physical highway barrier between the equity-emphasis-area communities on each side.  In the interests of environmental justice and sustainable transportation, it is essential that the Bypass include a robust network of paved (and natural-surface) trails for transportation and recreation, both along and across the stream valley.

* * *

5.  Please consider relocating the adjoining shared-use path–along the Bypass segment between Sudley Rd and the Bypass bridge over Flat Branch–to follow the west side of the Bypass, to facilitate access from the Fairmont, West Gate, and Sudley communities.

In addition, build local asphalt shared-path connections between the relocated shared-use path along the west side of the Bypass to the Fairmont, West Gate, and Sudley neighborhoods from at least these five locations:

Also, please ensure that all shared-use paths are generally designed to be as flat/level as the Bypass roadway, except where needed to achieve grade-separated roadway or stream crossings.  Provide physical barriers between the shared-use path and the roadway–such as non-mountable concrete curbs and/or jersey barriers–especially wherever the grass buffer between the shared-use path and the roadway would be less than eight feet wide

Justifications:  The Flat Branch stream would limit and complicate access to any shared-use path along the east side of the Bypass from the neighborhoods in Loch Lomond; any shared-use  along the Bypass requires frequently spaced connections to nearby neighborhoods for reasonable access by foot or bicycle; and any shared-use path near the Bypass must provide a physical barrier from roadway departures by high-speed motor vehicles.

 *  *  *

6.  Please consider developing and improving the existing UOSA access road to the east of the Bypass as a second, better separated shared-use path , with trail bridge connections across Flat Branch and its tributaries to serve the Loch Lomond neighborhood between Sudley Rd and Splashdown Waterpark.  This shared-use path should be extended beyond the current northern end of the UOSA access road, to parallel the remainder of the Bypass to its northern terminus along its east side.  Trails along UOSA easements are common in Fairfax County.

In addition, provide access to the UOSA access road/future shared-use path along the east side of the Bypass from the Loch Lomond neighborhood via asphalt shared-use paths (with ped/bike trail bridges across Flat Branch and/or its tributaries where necessary) from at least these eight locations:

Use trail underpasses in stream box culverts, the Bypass bridge over Flat Branch, or along both sides of Lomond Dr to connect the shared-use path along the current UOSA access road to the relocated shared-use path along the west side of the Bypass and from there to the Fairmont, West Gate, and Sudley communities.

Justification:  The area along Flat Branch should be developed into a linear park for enjoyment by the surrounding communities that would lack direct access to the new roadway.  By providing shared-use paths along both sides of the Bypass, the shared-use path connections under the Bypass would become much more effective in linking the low- and moderate-income, majority-minority communities that the Bypass would otherwise permanently sever

* * *

7.  Please design a shared-use path /trail connection under the Bypass bridge that crosses over Flat Branch.

Justification:  This connection would provide non-motorized access between communities on the east and west of the Bypass and provide communities on the east side of the Bypass with access to Splashdown Waterpark, thus reducing vehicle trips along neighborhood streets.  Moreover, north of the Bypass bridge over Flat Branch, only one shared-use path would be provided along the Bypass, on its east side, and the UOSA access road ends south of that crossing .  In other words, this trail connection would extend any adjacent shared-use path that begins on the west side of the Bypass at Sudley Rd though the remainder of the Bypass route.

* * *

8.  Please consider leaving all or part of the existing Old Centreville Rd Bridge over Bull Run in place as the Ped/Bike connection over the waterway.

Justification:  This reduces the cost to the project and is a much more pleasant access point and amenity to the surrounding community than walking or biking next to a 45-mph roadway

* * *

9.  Please consider including as part of the project planting hundreds/thousands of canopy trees to absorb and filter stormwater, reduce highway noise in the adjoining neighborhoods, and provide much-needed shade for trail users in warm and hot weather.  The trail(s) should also include user amenities such as trail lighting, benches, and trash receptacles.

Justification:  This project clearly bisects Equity Emphasis Areas while simultaneously not providing them access to the roadway.  It is imperative to add trail, park, and flood control amenities with the project to support the surrounding community.

* * *

Roadway Comments

10.  Please consider implementing a Continuous Green-T intersection at Route 28 Bypass/Old Centreville intersection.

Justification:  This allows for a non-stop southbound trip between existing Route 28 and Sudley Rd.

11.  Please consider providing some form of [emergency or uncontrolled] left turn capacity from Northbound Route 28 Bypass to Ordway Rd.

Justification:  During  incidents  in or around the Route 28/Compton Rd intersection, this capacity would provide a relief valve to clear traffic congestion more quickly

12.  Please consider adding a left turn from Route 28 Northbound to Route 28 Bypass Southbound (with access to Ordway Rd) and removing both left turns from Route 28 Compton Rd intersection.

Justification:  This creates a third light phase to the Route 28 Bypass/Route 28 intersection and reduces the Compton Rd/Route 28 intersection to three light phases.  Access via Ordway Rd provides the route to Compton Rd.  This will improve synchronization between the two adjacent light signals (Route 28/Route 28 Bypass & Route 28/Compton Rd).

Thank you for soliciting public comments at this early stage of project design.  We would be happy to meet with members of the project team to discuss these comments in more detail.

Sincerely,

Mark and Allen

Our Statement At The VDOT NoVA District’s Spring 2023 Joint Transportation Meeting


Annual Joint Transportation Meeting for Northern Virginia, May 1, 2023
Statement of Allen Muchnick, Member of the Virginia Bicycling Federation
and Active Prince William Boards of Directors

Good evening.  I’m Allen Muchnick.  I live in the City of Manassas, and I serve on the boards of the Virginia Bicycling Federation and Active Prince William, statewide and sub-regional active transportation advocacy organizations, respectively.

We thank VDOT for recently re-filling its statewide bicycle and pedestrian planner position and for staffing a new statewide trails office.  We look forward to seeing those offices advance safe active mobility.  We believe it’s time to review and update both VDOT’s 2011 State Bicycle Policy Plan and the CTB’s 2004 Policy for Integrating Bicycle and Pedestrian Accommodations.

I commend VDOT’s NoVA District Office for initiating a study to estimate the cost to complete all locally planned but unfunded bicycle and pedestrian facilities within the NoVA District.  While most NoVA localities have robust active mobility plans and even Vision Zero programs, Prince William County still lacks both, so its official inventory of missing pedestrian and bicycle facilities is woefully incomplete.

Since 2010, VDOT’s roadway reconfiguration program has cost-effectively retrofit bike lanes and pedestrian crossing improvements on many dozens of roadways during scheduled resurfacing, especially in Fairfax County.  Prince William County, however, has largely ignored this enormous opportunity to improve the access and safety of its vulnerable road users.  We urge the County and VDOT to actively implement this program in our communities.

The alignment of US Bicycle Route 1 through Prince William County is a prime example where retrofitted bike lanes or paved shoulders are desperately needed.  Although AASHTO and VDOT established this route more than 40 years ago and a VDOT consultant re-evaluated the route’s alignment through NoVA nearly a decade ago, the bicycling conditions on several Prince William route segments are horrendous.  For example, the County’s online Bicycle Skill Level Map labels Old Bridge Road, part of Minnieville Rd, Aden Rd, and Fleetwood Dr—all lacking bicycle facilities and posted at 45-MPH–as “Roads to Avoid” and tags Hoadly Rd and Tanyard Hill Rd as “Low Comfort”.  VDOT’s 2015 Bicycle Level of Service Map for the NoVA District rated those segments similarly.  It’s long past time for VDOT and the County to fix these embarrassing and potentially deadly deficiencies.

To address the ongoing epidemic of pedestrian fatalities, VDOT should aggressively implement design-speed reductions and pedestrian safety improvements along its multi-lane commercial arterials.  VDOT and Prince William should also establish safer bike/ped crossings of I-95 and I-66 and extend the I-66 Trail, now being built in Fairfax County, over Bull Run to connect to both Balls Ford Rd and the Northern Virginia Community College’s Manassas campus.

In closing, we strongly support the recommended SMART SCALE, CMAQ, and RSTP awards for Manassas, Manassas Park, and Prince William County.

Thank you for this opportunity to comment.

Our Input for the Route 234-Clover Hill Road Bowtie Intersection

2017 Concept for a Clover Hill Road/Prince William Parkway “Bowtie” Intersection

Recently, the Prince William County Department of Transportation asked for our feedback on their proposed preliminary design for rebuilding the intersection of the Prince William Parkway (Route 234) and Clover Hill Road near Manassas as an “innovative” bowtie intersection, where all direct left turns are eliminated and instead accommodated via two roundabouts on the minor cross street.   Our reply is posted below.   We will track this upcoming project in the coming years as the design is refined for construction.


Thank you for soliciting Active Prince William’s input on how the redesigned intersection of Clover Hill Road at the Prince William Parkway can best serve people walking and bicycling.

Conventional On-Road Bike Lanes Are Appropriate for Clover Hill Road

Clover Hill Road provides an important low-traffic bicycling connection between the City of Manassas (and adjacent residential neighborhoods within the County) and Manassas Regional Airport and points west, including the Broad Run VRE station and the new Route 28 shared-use path that now extends though Bristow all the way to Nokesville.  On the southwest side of Route 234, Clover Hill Road provides critical bicycling access to a network of low-traffic, bicycling-friendly roads within and near Manassas Regional Airport, including Harry J Parrish Blvd. Wakeman Drive, Observation Drive, Piper Lane, Residency Road, Pennsylvania Avenue, Carolina Drive, and Gateway Blvd.

As such, Clover Hill Road is eminently useful for bicycle commuting to employment sites within and near the airport, to the Broad Run VRE station, and to points west in Bristow.  In addition, Clover Hill Road and the low-traffic roads within and around the airport are used extensively for recreational bicycling on evenings and weekends.

Bicyclists on Bull Run Bicycle’s Tuesday evening shop ride wait to cross Route 234 at Clover Hill Road. To avoid hazardous right-turning traffic on both sides of this intersection, the group waits for a green traffic signal in the left travel lane of Clover Hill Road.

Both City of Manassas roadways that connect to this segment of Clover Hill Road–i.e.. Clover Hill Road from Godwin Drive to Wellington Road and Godwin Drive from Clover Hill Road to Hastings Drive–already have conventional on-road bike lanes.  Thus, in addition to including sidewalks for pedestrians, the entire redesigned segment of Clover Hill Road should include conventional on-road bike lanes in both directions.

Note that VDOT’s website that describes bowtie intersections includes conventional on-road bike lanes on all four legs of that intersection (see the illustration copied below).

Since, as in the above illustration, the proposed design features dedicated right-turn-only lanes on Clover Hill Road at both approaches to the Prince William Parkway, it would be vital to install the bike lanes at both approaches to the Prince William Parkway between the straight-through travel lane on the left and the right-turn-only lane at the curb.

Within the roundabouts, the bike lanes–if any–should be on the far right and could be buffered or physically separated from roadway traffic.  Alternatively, especially if right-of-way is constrained at the roundabouts, the bike lanes could be discontinued within the roundabouts and bicyclists encouraged to navigate the roundabouts as either a driver centered within the travel lane or (using strategically placed curb ramps for access and egress) as a pedestrian using the sidewalk.

However, upon exiting each roundabout, right-turning motorists should be directed to yield to any bicycle traffic ahead and to carefully merge right across the continued bike lane to enter the emerging right-turn-only lane before reaching either the Parkway (along both southbound and northbound Clover Hill Road) or Godwin Drive (along northbound Clover Hill Road).

Please note that these same conflicts between right-turning motorists and straight-through bicyclists presently exist at the current Clover Hill Road/Route 234 Intersection in the absence of any bike lanes and that appropriate traffic engineering measures, involving pavement markings and signage, can optimize the safety of all road users.

Design This Intersection to Safely Accommodate the Future Shared-Use Path Along Route 234

Although this project won’t construct the long-planned missing shared-use path along Route 234, the design of this intersection should not preclude its future construction and should also ensure that pedestrians and bicyclists using that shared-use path can cross Clover Hill Road safely.  As a designated segment of the National Capital Trail Network, a continuous, high-quality shared-use path along Route 234 should be a priority for Prince William County.

Unobstructed right-of-way should be acquired and preserved as part of this project to accommodate the future Route 234 shared-use path, and the project design should ensure that the route and future design of this path would not be blocked or compromised by noise barriers, above-ground or buried utilities, or roadside signage, traffic signals, or street lighting.  Until the county decides whether this path will be constructed on the northeast or southwest side of Route 234, right-of-way should be reserved for the future shared-use path on both sides.

In addition, the intersection design should ensure that the future Route 234 Trail will have a safe, at-grade crossing of Clover Hill Road, presumably coordinated with the same traffic signal that regulates the Route 234 traffic.

Eliminate High-Speed Right-on-Red Turning Movements from Route 234 onto Clover Hill Road

Unlike VDOT’s model bowtie intersection illustrated above, the currently proposed intersection design incorporates two free-flowing, high-speed, right-turning movements, using pork-chop islands, for Route 234 traffic to enter Clover Hill Road.  We believe this currently proposed design feature would seriously endanger both 1) bicyclists and pedestrians crossing Route 234 at Clover Hill Road and 2) the users of the future Route 234 Trail crossing Clover Hill Road.

Vulnerable, non-motorized road and trail users who are crossing either roadway on a green traffic signal should not be endangered by high-speed traffic that is simultaneously turning right-on-red at near-freeway speeds at these pork-chop islands.  While a decision to completely ban all right-turn-on-red movements at this intersection might best be made by expert traffic engineers, we firmly believe that free-flowing right-on-red movements would be dangerous at this intersection and should not be promoted by design features such as pork-chop islands.

Instead, vehicle traffic entering Clover Hill Road from Route 234 should be encouraged to slow to the 25 MPH posted speed and carefully merge into the single travel lane approaching the roundabout, while bicyclists who have just crossed Route 234 on a green signal must merge into the bike lane at the right edge of the roadway.

Again, careful pavement marking and signing would help all road users safely negotiate these conflicts, whereas a design that promotes high-speed right-on-red vehicle traffic would endanger vulnerable road users.

Bicyclists and pedestrians crossing Route 234 at Clover Hill Road on a green traffic signal would primarily be endangered by motorists turning right-on-red from Route 234 at the far side of their crossing.  By contrast, users of the future Route 234 Trail crossing Clover Hill Road on a green traffic signal could encounter both motorists turning right-on-green from Route 234 as well as motorists turning right-on-red from Clover Hill Road.   All such right-turning movements would be safer if the design encourages motorists to slow or stop completely before entering a crosswalk and turning into the path of vulnerable road users.  Partial traffic signal phasing, such as leading pedestrian intervals, could also make these crossings safer.

Clover Hill Road is a local street posted for 25 MPH, and there is no compelling need to promote free-flowing right-turn-on-red vehicle movements onto Clover Hill Road.

The 2019 AADT for all connected local roadways (i.e., Clover Hill Road, Godwin Drive, and Harry J Parrish Blvd) ranges from 2100 to 4700, so Clover Hill Road only needs one travel lane per direction between intersections. The proposed design includes a grassy median along Clover Hill Road, but there’s no compelling need for a grassy median on a road posted for 25 MPH, and that grassy median is about a full-lane wide on the segment approaching Godwin Dr.

Active Prince William also supports the inclusion of a shared-use path along this entire segment of Clover Hill Road; however, such a path would not connect to any existing path along Clover Hill Road, Godwin Drive or Harry J. Parrish Blvd, and it appears that the long-planned path along the Route 234 Bypass won’t be built for the foreseeable future.  Thus, a shared-use path seems less essential, especially on the airport side of Route 234, provided that both sides of Clover Hill Road will have sidewalks and bike lanes.

If spatial or terrain constraints would otherwise preclude the addition of both on-road bike lanes and sidewalks along Clover Hill Road in both directions, consideration should be given to narrowing or eliminating the grassy medians.

Thank you for considering our input.
