Detours
Traffic leaving the Tysons Corner shopping areas to McLean will be detoured from Route 123 north to I-495 south to Route 7 and back to I-495 north to continue on Route 123 north. Traffic heading to Tysons from McLean will be directed to use I-495 north to Georgetown Pike (Route 193) to I-495 south back to Route 123 south. Motorists should expect delays around the Route 123/I-495 interchange and on Georgetown Pike and Route 7. Police will be onsite to direct traffic.

Once the old beltway bridge is demolished, crews will begin construction on the new beltway bridges and continue work on a new HOT lanes connection into Tysons Corner at the Westpark Drive bridge. Crews will also continue construction of Dulles Metrorail guideway piers over the Capital Beltway. Should inclement weather cancel the closure, it will be rescheduled for October 22-25.
