Allow for extra travel time this weekend as parts of MD-295, or the Baltimore-Washington Parkway, will be closed for the next two weekends for a highway improvement project.

The Maryland Department of Transportation said it will shut down southbound lanes on MD-295 on Friday night through Monday morning. The northbound lanes will be closed the following weekend for the same duration. MDOT will close the lanes so its crews can demolish the existing MD-175, or Annapolis Road, bridge. The main-line lanes on the new bridge will be open.

The department said there will be crews and signs helping detour drivers from the closed section of the highway to MD-100, Interstate 95 and MD-32.

To get to Baltimore-Washington International Thurgood Marshall Airport, MDOT recommended that drivers use other routes along I-95, US 1 or I-195. All lane closures will happen as long as the weather allows for crews to work.
