Project Overview• Widening Fairfax County
Parkway to provide third lane in each direction
• Improvements to intersections within project limits
• Interchange at Popes Head Road• Includes access to future FCPA
Access to Patriot Park and the future extension of Shirley Gate Road
• Upgrades to shared use path • Stormwater management• NEPA document and noise study

Burke Centre Parkway Intersection Options
Prohibit Left Turns from Burke Centre Parkway• Improved safety and increased southbound and northbound Fairfax
County Parkway green time• Southbound traffic will only stop when pedestrian crossing signal
is activated
Virginia Department of Transportation
Burke Centre Parkway Intersection Options
Continuous Green-T (CGT)• Improved safety and increased southbound Fairfax County Parkway
green time • Southbound traffic will only stop when pedestrian crossing signal
is activated
Virginia Department of Transportation
Burke Centre Parkway Intersection OptionsNew Option Based on Feedback
Right-In / Right-Out• Eliminates existing traffic signal• Requires relocation of pedestrian crossing across Fairfax County
Parkway • Diverts southbound left turn traffic to Route 123 Interchange• Prohibits U-turn at Burke Centre Parkway
• Operational modifications to Fairfax County Parkway at Ox Road interchange are being coordinated with Fairfax County
• Traffic analysis ongoing• Potential improvements
include:• Exit/Entrance ramp
improvements• Transition from 3 to 2 lanes on

Popes Head Rd/Shirley Gate RdExtension Interchange AlternativesCompressed Diamond
• Direct access to Shirley Gate Road Extension
• Access to Popes Head Road via new Connector Road
Double Roundabout• Direct access to Shirley Gate Road
Extension with connections to realigned Popes Head Road
• One bridge over Fairfax County Parkway
Split Diamond• Direct access to Popes Head Road
and Shirley Gate Road Extension• Similar to interchange at Fair Lakes

Pedestrian and Bicycle Facilities• The project corridor contains an existing 8-foot multi-use asphalt trail
from Lee Highway to Burke Centre Parkway:• Along east side of FCP from Lee Highway to Braddock Road• Along west side of FCP from Braddock Road to Burke Centre Parkway
• There are two elements to treating stormwater runoff• Water Quality Control
• Occoquan Watershed requires on-site mitigation
• Water Quantity Control• Tools for achieving water
quality / quantity goals

NEPA Environmental Assessment Primary Points of Focus• Noise Study (23 CFR 772)• Air Quality• Section 7 of Endangered
Species Act• Section 106 of National
Historic Preservation Act• Section 404, 401 Clean Water
Act• Section 4(f) of Department of
Transportation Act

Noise Analysis Study Area
15
• As part of the environmental analysis conducted during the NEPA analysis, VDOT will conduct a noise impact assessment which will include:
Identifying noise receptors (such as residences, schools, parks, etc.)Conducting noise monitoring in the field Conducting noise modelingIdentifying impacts Designing and assessing mitigationPreparing and presenting noise study results and preliminary noise wall locations (if necessary) at public meetings.

66 dB Noise Abatement Criteria for Residential homes
Virginia Department of Transportation
Noise BarriersFeasibility
• Does it work acoustically?• VDOT requires that 50% or more of the impacted receptors
experience 5 dB(A) or more of noise reduction to be feasible;
• Can it be constructed?• Factors related to design and
construction include: safety, barrier height, topography, drainage, utilities, and maintenance of the abatement measure, maintenance access to adjacent properties, and general access to adjacent properties
AND
Example of location where sound barrier would not be feasible due
to spacing of driveways
Virginia Department of Transportation
Noise Barriers• Reasonable
• Cost-effectiveness• Maximum 1,600 sq ft of noise
barrier or less per benefited residence
• Design goal• 7 decibels of noise reduction at 1 impacted receptor
• Viewpoints of the benefited receptors• Democratic vote of the benefited receptors• 50% of the benefited respondents must favor construction• Partial mitigation may occur as a result of the vote
