The left lane, one in each direction on Route 123 (Chain Bridge Road) under the Beltway in Tysons Corner will close beginning Sunday, June 27 at 9:30 p.m. for 18-24 months, weather permitting.
The north and southbound lane closures are necessary to provide construction room to build the new I-495 north bridge piers and HOT Lanes connections into Tysons Corner.
During peak morning and afternoon hours motorists should expect up to 15-minute delays. Route 123 will have two through traffic lanes and one merge lane in each direction. This closure was in place last year while crews built the new I-495 south bridge over Route 123.
