If you’re commuting through northern Montgomery County this evening, you may want to consider an alternate route, like MD-355.

The State Highway Administration warns of delays in the Clarksburg area, while construction closes both directions of i-270 periodically around midnight.

A private contractor is expanding a bridge on MD-121 to appease traffic when the Clarksburg Premium Outlets open in October.

They’re working northbound tonight, so expect more lane closures in that direction.

“After midnight there will be temporary 15-minute long stoppages, so the crane can go ahead and swing the 20-ton beam into place and for crews to go ahead and secure it,” said Charlie Gischlar, SHA Spokesperson.

Construction is expected to finish by the end of the week, but rain could delay its schedule.
