NEW BRIDGE OPEN AND RAMPS RESTORED IN TYSONS CORNER
Relief in sight for Route 123


ALEXANDRIA— Due to this weekend’s forecasted inclement weather, all work along I-495 north and Route 123 (Chain Bridge Road) in Tysons Corner has been rescheduled for Nov. 4-6.

Weather permitting, by Monday morning rush, Nov. 7, all four lanes of I-495 north will shift to the right onto a new bridge over Route 123 (Chain Bridge Road), Exit 46, in Tysons Corner. Shifting northbound Beltway traffic allows the reopening of the Route 123 north on-ramp to I-495 north and the removal of the left turn lanes and traffic signal. Since last Oct. 2010, motorists traveling in both directions on the Beltway have shared the new southbound bridge over Route 123. 

Crews will also restore the left lanes on Route 123 in both directions at I-495 bringing the roadway back to full capacity with three through lanes and reconfigure the ramp from I-495 north to Exit 46A, Route 123 south. This ramp will be one lane with the merge lane restored on Route 123 and the traffic signal removed.

To prepare for these changes, crews will begin a two-night operation starting at 9 p.m. Friday, Nov. 4, until 8:30 a.m. Saturday, Nov. 5. During this time the three right lanes on I-495 north from Leesburg Pike (Route 7) to the Dulles Toll Road (Route 267) will be closed to prepare for the traffic shift. Ramps from I-495 north, Leesburg Pike and Route 123 will also be closed withh detours in place.  

On Saturday night, Nov. 5, from 9 p.m. until 9 a.m. Sunday, Nov. 6, crews will close two left lanes on Route 123 to restore the left lanes, remove the traffic signals and reopen the ramp from Route 123 north to I-495 north. Ramps from I-495 north and Route 123 will also be closed with detours in place.

Should inclement weather cancel this work it will be rescheduled. Crews may also work Sunday night, Nov. 6, as a backup. 

As part of the Capital Beltway HOT Lanes Project, in Oct. 2010, crews closed the Route 123 north to I-495 north ramp and installed the traffic signals to start rebuilding the I-495 north overpass. This work was originally scheduled to occur into late 2012 and is being delivered ahead of schedule.
