Update: As Allie points out in the comments, the press release says five weeks and the sign says two. I’m betting on five.
From the press release (bolding mine)
Route 691 (Jarmans Gap Road) will be closed to traffic at the Route 240 (Crozet Avenue) intersection for five weeks beginning Sept. 15. The closure is necessary so Dominion Virginia Power can relocate its overhead power lines into underground facilities.
Traffic traveling east on Route 691 will be detoured onto Old Trail Drive, then onto Route 250 east and back onto Route 240 south of the Route 691 intersection. Traffic headed onto Route 691 from Route 240 will continue south to Route 250, then west to Old Trail Drive and back to Route 691.
Dominion Virginia Power’s work on its electric service is part of the utility relocation work now under way along Route 691. That utility work is necessary prior to the beginning of construction of the Virginia Department of Transportation’s Jarmans Gap Road improvement project, which is scheduled to begin in the spring of 2011.
The project is designed to improve safety for motorists as well as the bicyclists and pedestrians using that road. The improvements will include wider travel lanes, the addition of bike lanes, and construction of curb and gutter and sidewalk. Once completed Route 691 will have 12-foot wide travel lanes, a four-foot wide bicycle lane on each side of the road, curb and gutter on both sides of the roadway and sidewalk on the northern side of Route 691.
