Dulles Metrorail Project: Rts. 123 & 7 Construction Map Fall 2009 - Mid 2010

This is like a mixed feeling. On one hand, it's exciting to watch the recent development around the area. And on the other hand, this project creates headaches for businesses and those working out of Tysons, McLean areas, especially surrounding Route 123 and Route 7. So, expect major changes along the 1-mile construction zone on Route 7 and Route 123. 

 

Some of the traffic changes coming in the next couple of weeks, via Dulles Metro:

• The service roads along the edges of the east and west bound lanes of Route 7 will be closed so that the edges of Route 7 itself can be pushed out to the edges of the service roads and beyond to make room for construction of the rail line and stations in the median of the road bed.
• Near the two stations to be built along Route 7-Tysons Central 7 (near SAIC and Marshalls) and Tysons West (between Spring Hill and Tyco Roads), the eastbound lanes will balloon out into the parking areas of some businesses.
• Also, along the eastbound lanes, crews will be building retention walls to support the new road bed as crews must build up many existing service roads to the levels of Route 7.
• Mid-block left turns will be eliminated. Drivers will be encouraged to make U-turns at the existing signalized intersections: Westwood/Tyco, Spring Hill and Gosnell/Westpark.
• A major lane shift has already taken place on Route 7, beginning at the Route 123 overpass.
• The traffic signal at Route 7 from the Route 123 exit to Winchester and Reston has been removed.
• The ramp from Route 7 to southbound Route 123 has been relocated.
