(May 14, 2026) – The Maryland Department of Transportation State Highway Administration is starting a project to improve the driving surface of the northbound US 29 ramps to the eastbound and westbound directions of Broken Land Parkway in Columbia. The work will begin this Sunday, May 17 and be completed by June, weather permitting.   

Crews will work weeknights from 8 p.m. to 5 a.m. the following morning. The northbound  US 29 ramp to both directions of Broken Land Parkway will close starting at 10 p.m. on work nights.
