Tysons ramp reopening, after completion of Silver Line tunnel

The Dulles Metrorail project on Friday plans to reopen a long-closed ramp at a key intersection in Tysons Corner, a move that should improve traffic flow in this congested area.

By 5 a.m. Friday, drivers should once again be able to use the ramp that leads from southbound Route 123 to westbound Route 7. The change in the traffic pattern is possible because the rail tunnel for the Silver Line is completed.

Good-bye, and good riddance, to the temporary ramp. Out of all the changes that drivers have had to deal with during this massive project, the changes at the Route 123/Route 7 interchange were among the most difficult.

When the old ramp is restored and the temporary ramp closes, Frontage Road will be back the way it was before the project started. Drivers who want to reach Frontage Road will need to use the entrances from International Drive or Pinnacle Drive.
