WASHINGTON - The Maryland State Highway Administration is leading an effort with the National Park Service (NPS) to repair the MD 198 interchange, the number one maintenance priority on the Baltimore-Washington Parkway. Work begins tonight, June 13.

“This is a great example of how Federal and State organizations can collaborate to create safe and smooth conditions for drivers,” Superintendent Matthew Carroll said. “We are grateful for the funding support from the Maryland State Highway Administration to help repair this important and scenic national park road that is also a critical transportation artery for Maryland drivers and commuters.”

The $350,000 repair project will mill and pave the northbound Baltimore-Washington Parkway entrance ramp at MD 198 West, and the acceleration and deceleration lanes on the parkway. Lane marker re-striping is also part of the project.  

In an effort to minimize traffic impacts, repairs will be performed weeknights between 9 p.m. and 5 a.m. from Monday, June 13 through Thursday, June 16. The project is weather dependent, and if the project is not complete by June 16, repairs will resume Monday, June 20. Throughout the project, at least one lane on the northbound Baltimore-Washington Parkway will remain open at all times.

Opened in October 1954, the Baltimore-Washington Parkway is a 29-mile route that runs between the eastern boundary of Baltimore, Md. and the District of Columbia. Originally designed to serve as a dignified entrance to the nation’s capital, a military access route for Federal installations and alternative to US Route 1, the Baltimore-Washington Parkway now serves as one of the most important components of the region's transportation network.
