Interstate 170 at Delmar Boulevard will be closed this weekend, beginning at 7 p.m. Friday.

Crews have to set girders and install portions of the driving surface of a new Delmar bridge.

 Andrew Gates, a spokesman for the Missouri Department of Transportation, says traffic will be detoured from the interstate up the ramps at Delmar and then back down onto the interstate.
