ALEXANDRIA - UPDATED All lanes on Route 123 (Chain Bridge Road) at I-495 in Tysons Corner are open as of Sunday, Oct. 17, more than 14 hours ahead of schedule as part of the ongoing Capital Beltway High Occupancy Toll (HOT) Lanes Project.

Route 123: All lanes closed weekend of Oct. 15

All four lanes of Route 123 under the Beltway in Tysons Corner will close beginning 9:30 p.m. Friday, Oct. 15, through 5 a.m. Monday, Oct. 18 for demolition of the old northbound I-495 bridge. See the newspaper ad (1.2 MB). The following ramps will be closed all weekend:

  • I-495 South to Route 123 North
  • Route 123 south to I-495 South
  • Route 123 north to I-495 North

Route 123 detours for Oct. 15-18

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 on site to direct traffic. VDOT urges motorists familiar with the area to use alternate routes.

Beltway traffic shift underway

Starting at 9 p.m. Wednesday, Oct. 13, crews will begin closing lanes at Exit 46 to prepare for a Beltway traffic shift. On the morning of Oct. 14, all four lanes of northbound I-495 lanes will shift left at Exit 46, in Tysons Corner. Once motorists cross over Route 123 all four lanes will shift back to the right to tie-in with the existing Beltway. This new traffic pattern will be in effect for up to two years.  Motorists need to be prepared for a two-lane ramp leading to a new traffic signal exiting from northbound I-495 to Tysons/Vienna (Exit 46A.) Motorists should use caution and expect delays in this area during peak travel times.

Long-term Route 123 north ramp closure

Starting at 5 a.m. Oct. 13, the ramp from Route 123 north to I-495 north will close for up to two years. Motorists will need to merge to the left on northbound Route 123 and turn left at a new traffic signal just before Capital One. The new turn lanes will allow for a dual left turn to enter onto I-495 north. Traffic merging onto I-495 north from Route 123 south will now yield to traffic taking the new signalized left turn onto I-495 north. Motorists should expect additional delays in this area during peak travel times. See the newspaper ad (1.2 MB).
