[related_gallery align=”none”]The new Frederick Douglass Memorial Bridge with its distinctive triple arches began welcoming drivers this weekend.

But with some construction activity and testing remaining, there’ll be some scheduled nighttime stoppages in the weeks ahead.

The D.C. Department of Transportation plans multiple traffic stoppages in both directions from Sept. 15 to Sept. 29.

The disruptions will occur nearly each weeknight between 9 p.m. and 6 a.m. Traffic will be stopped for as long as 15 minutes before moving again.

DDOT promises to avoid impacting game nights at Nationals Park and Audi Field.

The new six-lane suspension bridge also accommodates bicyclists and pedestrians.

The $441 million dollar bridge is the biggest infrastructure project in the history of the District of Columbia.
