2016 Draft VDOT Repaving List• Projects are being proposed in conjunction with VDOT regular maintenance

• Only changes to striping of existing paved area are possible at this time• No additional concrete work• No road widening

• No significant additional cost to Fairfax County or VDOT to implement proposed changes



Bicycle Facility Types• Sharrow-Shared Lane Markings (SLMs), or “sharrows,” are road

markings used to indicate a shared lane environment for bicycles and automobiles. Among other benefits shared lane markings reinforce the legitimacy of bicycle traffic on the street, recommend proper bicyclist positioning, and may be configured to offer directional and wayfinding guidance


Bicycle Facility Types• Bike Lane-Bike lanes designate an exclusive space for bicyclists

through the use of pavement markings and signage. The bike lane is located adjacent to motor vehicle travel lanes and flows in the same direction as motor vehicle traffic. Bike lanes are typically on the right side of the street, between the adjacent travel lane and curb, road edge, or parking lane.


Bicycle Facility Types• Buffered Bike Lane-Buffered bike lanes are conventional bicycle

lanes paired with a designated buffer space separating the bicycle lane from the adjacent motor vehicle travel lane and/or parking lane.


Bicycle Facility Types• Paved Shoulders-At least 3’ wide, and provide a bicycle facility along

uncurbed roadways that serve lower density residential communities. Allows for parking to remain, especially on gravel sections.


Coffer Woods Road• From Burke Centre Pkwy to Burke Lake Rd• Bicycle Master Plan calls for on-road bike lanes• Average Daily Traffic: 5,200• Speed Limit: 35 mph• 2 Sections based on roadway width

• Burke Center Parkway to New England Woods: Bike Lanes• New England Woods to Burke Lake Rd: Sharrows or Paved

Shoulders-depends on VDOT maintenance decisions



Coffer Woods Road



Coffer Woods Road• Burke Center Parkway to New England Woods: Bike

Lanes (36’+ of pavement)



Coffer Woods Road• Narrow existing travel lanes and add bike lanes



Coffer Woods Road• New England Woods to Burke Lake Rd: Sharrows or

Paved Shoulders-depends on VDOT maintenance decisions (25’ of pavement)



Coffer Woods Road• New England Woods to Burke Lake Rd: Sharrows and/or

Paved Shoulders-depends on VDOT maintenance decisions (25’ of pavement)



Braeburn Dr• From Guinea Rd to Wakefield Chapel Rd• Bicycle Master Plan calls for sharrows, however the

pavement width is wide enough to allow for bike lanes• Average Daily Traffic: 1,400• Speed Limit: 25 mph• Cross section would keep parking, add bike lanes, and

keep 1 travel lane, in each direction• Narrow travel lanes have traffic calming effect



Braeburn Dr



Patriot Dr• From Heritage Dr to Americana Dr• Bicycle Master Plan calls for Bike Lanes• Average Daily Traffic: 2,700• Proposed roadway design same as Braeburn Dr, which

includes 1 travel lane, 1 bike lane, and 1 parking lane in each direction



Patriot Dr



Patriot Dr


Existing Proposed


Queensberry Ave• From Braddock Rd to Heming Ave• Bicycle Master Plan Calls for Bike Lanes/Climbing Lane• Average Daily Traffic: 3,000-5,000• Speed Limit: 25 mph• Braddock Rd to Ravenel Ln: 1 travel lane, 1 bike lane, 1

parking lane each direction• Ravenel Ln to Heming Ave: Keeps existing lane

configuration, but adds sharrows. Not enough pavement width for bike lanes



Queensberry Ave



Queensberry Ave-Braddock Rd to Ravenel Ln


Existing Proposed


Queensberry Ave-Ravenel Ln to Heming Ave


Existing Proposed


Guinea Rd• From Little River Turnpike to Braddock Rd• Bicycle Master Plan calls for bike lanes• Focused on Section from Braeburn Dr to Little River Tpke

• 4 lane undivided from Little River Turnpike to Braeburn Dr (44’+)• Road Diet Proposed from Braeburn Dr to Ashmeade Dr

• History of crashes, including 10 rear end crashes in three years, 18 total in this section alone

• Not only a project to add bike lanes, also for road safety

• Existing configuration would remain from Braddock Rd to Braeburn Dr and from Ashmeade Dr to Little River Turnpike



Guinea Rd

• 12,000+ Vehicles per day in proposed road diet section

• Speed Limit: 35 mph


Guinea Rd• 2 Lane street from

Braddock Rd to Braeburn Dr

• Proposal would continue one lane in each direction to Ashmeade Dr



Guinea Rd• 4 lane undivided from Braeburn Dr to Little River Turnpike (44’+)



Guinea Rd• 4 lane undivided from Braeburn Dr to Little River Turnpike• Proposal would be to implement a road diet

• Braeburn Dr to Ashmeade Dr-Existing section to south is 1 lane in each direction, proposal would extend one lane section to Ashmeade Dr


Existing Proposed


Guinea Rd• Road Diet proposal



Guinea Rd• Road Diets

• Have now implemented road diets in several places in the county• Soapstone Dr, Lawyers Rd, Kingstowne Village Parkway, Westbranch Dr,

Greensboro Dr, Park Run Dr, Beacon Hill Road,

• Benefits for all users: drivers, pedestrians, and bicyclists• Drivers: Reduction in top end speeding, 15mph>, provides dedicated turn lane at

intersection=reduction in rear end crashes=safer streets• Pedestrians: Shorter distances to cross the street, less speeding=safer streets• Bicyclists: Provides dedicated space to ride, not blocking flow of vehicle traffic,

reduced conflicts and potential for crashes=safer streets



In existing conditions, if a driver moves slightly over the double yellow line thereis a risk for a head-on crash. In the proposed design, center turn lanes provide a buffer from oncoming traffic.

Existing Proposed


Existing Proposed

In existing conditions, if a driver swerves slightly to the right, there is a risk for a collision with the curb. In the proposed design, bikes lanes provide buffer from curb, although the bike lane shouldn’t be regularly used by drivers.


Existing Proposed

In existing conditions, if a driver pulls over with disabled vehicle, there is a riskof being in a rear-end collision. In the proposed design, bike lane can provide safe area during emergency conditions, and help to avoid a rear-end collision.


Existing Proposed

In existing conditions, if a driver is waiting for traffic to clear to make a left turn, there is a risk of a rear-end collision. In the proposed design, left turn lanes provide dedicated space to make turn, out of the way of through traffic.


Existing Proposed

In existing conditions, if two drivers are making left turns, they block each otherssight distance and view of oncoming traffic. In the proposed design, turn lanes provide better sight lines and view of oncoming traffic.


Existing

In existing conditions, the sight lines for drivers exiting side streets can make itdifficult to see oncoming traffic. In the proposed design, the through lane is awayfrom the curb, and a driver has a better view of oncoming vehicles.
