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

• 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.

• 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.

• 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

Braeburn Dr
• From Guinea Rd to Wakefield Chapel Rd

pavement width is wide enough to allow for bike lanes
• Cross section would keep parking, add bike lanes, and
keep 1 travel lane, in each direction
• Narrow travel lanes have traffic calming effect

Existing Proposed

Guinea Rd
• Road Diet proposal
30

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 there
is 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 risk
of 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 others
sight 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 it
difficult to see oncoming traffic. In the proposed design, the through lane is away
from the curb, and a driver has a better view of oncoming vehicles.
