How to ease traffic on Hunter Mill Road, a two-lane country road in the increasingly urban Reston-Vienna area, will be the subject of a community meeting this week.
The Fairfax County Department of Transportation (FCDOT) meeting (Thursday, Sept. 15 at 7 p.m., at Aldrin Elementary School, 11375 Center Harbor Rd. in Reston), is actually the fifth on this topic since 2014.
FCDOT officials will talk about the project status and next steps.
At the most recent meeting in late June, transportation officials showed results of a new traffic impact study that showed installing roundabouts could result in fewer traffic backups.
Project manager Kristin Calkins said then that the project is still years away as the county continues to look at models and obtain citizen feedback. There also is no money set aside for the roundabouts as county transportation projects are planned and funded through 2020.
In any case, FCDOT is looking at what roundabouts would do at Sunrise Valley Drive and Hunter Mill Road, on Dulles Toll Road eastbound and westbound exit ramps at Hunter Mill, and at Sunset Hills Road and Crowell Drive, which would also be realigned to connect and further smooth traffic on Hunter Mill.
Some of those intersections/road areas are currently at an unacceptable level of service, said Calkins. Roundabouts would bring them up to an acceptable level when the county looks at the increased volume expected to be on the roads in 2030.
In addition to the roundabouts, the county would like to upgrade the area on Hunter Mill from Sunrise Valley Drive to Route 7 that is served by a one-lane bridge.
“It’s been found to be structurally deficient and functionally obsolete,” said Calkins. “Hunter Mill Road carries 7,900 vehicles a day. That warrants a two-lane bridge.”
Calkins said an acceptable amount of traffic for a road with a one-lane bridge is 400 cars per day.
