Project Objectives
• Address existing congestion
• Plan for future traffic
• Address queuing along Hunter Mill Road and Sunset Hills Road
• Improve access to the Dulles Toll Road by minimizing congestion
• Maintain Hunter Mill Road’s character by applying context sensitive solutions
4
Project Background
• Board of Supervisors requested study
• “No Build” includes proffered improvements from the Oakcrest School rezoning
• Two meetings held thus far:
o December 8, 2014: Kick-Off
o February 24, 2015: Existing & No-Build conditions and community input on alternatives

Summary of Community Comments
• Do not want traffic from Wiehle Avenue diverted to Hunter Mill Road
• Concerns that the signal at Crowell Road may increase delays in the off-peak
• Roundabouts should be seriously examined as an alternative for the corridor
• Keep Hunter Mill Road’s character the same
• Concern that improvements may attract more traffic

Response to Community Questions
• Will these improvements attract vehicles to Hunter Mill Road?
o Trips will divert from Hunter Mill Road and use Crowell. The improvement will not add new trips to the road network, but divert local trips.
• Can more lanes be accommodated under the existing Toll Road Structures?o More lanes cannot feasibly be accommodated under the DTR.
The piers for the Dulles Access Road are load bearing and would need to be replaced. Replacement of just the two bridges would be near $40 million, not including the cost of improving Hunter Mill Road.
10
Response to Community Questions
• Will a signal at Crowell Road and Hunter Mill Road increase delays in the off peak?o An actuated signal can be used in the off peak to minimize
the delays of vehicles on Crowell Road.
• Why not consider moving the ramps of the Dulles Toll Road?o Prior to modifying the ramp termini of the Dulles Toll Road
all viable and workable alternatives need to be tested to see if they work. Changing the Toll Road intersections is a last step measure to improve the corridor as it would require a federal review and a much more time consuming process.
11
Community Input on Alternatives
• Test an all Roundabout Solution• Test extending the right turn lane on southbound
Hunter Mill Road before the intersection of Sunrise Valley Drive
• See if additional lanes can be added underneath the Dulles Toll Road
• Test a realigned Sunset Hills Road• To a mid point between the current location and Crowell
Road• To Crowell Road
Future Conditions - Geometry
• Hunter Mill RoadMinor Arterial (Type B)
o 1 Lane in each direction (north of Sunset Hills Road)
o 2 Lanes Northbound, 1 Lane Southbound (south of Dulles Toll Road)
o 35 miles per hour speed limit
• Sunrise Valley Driveo Minor Arterial (Type B)
o 1 Lane in each direction (East of Hunter Mill Road)
o 2 Lanes in each direction (West of Hunter Mill Road)
o 35 miles per hour speed limit

• Sunset Hills Roado Minor Arterial (Type B)
o 2 Lanes in each direction
o 35 miles per hour speed limit
• Crowell Roado Minor Arterial (Type B)
o 1 Lane in each direction

Findings/Conclusions• Signalized Alternatives performs best at Hunter
Mill Road and Sunrise Valley Drive
• All alternatives approximately same at DTR eastbound ramps
• Alternative 1A (roundabout with DTR Ramp and Sunset Hills Road) performs the worst at DTR westbound ramps
31
Findings/Conclusions (Cont’d)• The signalized alternatives perform best at DTR
westbound ramps
• Sunset Hills Road operates best when realigned to the north
• Corridor likely not “One Size Fits All” – Mix and match of alternatives might be solution
