The Maryland State Highway Administration and Anne Arundel County have announced a $113.8 million project to widen miles of Interstate 97 between Maryland Route 32 in the Millersville area to U.S. Routes 50\301 in Annapolis.
I-97 is a critical artery in Anne Arundel County for residents, students, commuters and those visiting Annapolis. The highway includes six travel lanes before tapering to four, which can back up significantly during the summer as Maryland families head to the beaches and to Baltimore-Washington International Thurgood Airport.
Major construction is expected to begin in 2028. This project has been named a priority by Anne Arundel County, which is contributing $10.6 million toward project planning and construction.
Between 94,000 and 113,400 vehicles travel along this busy interstate each day. Projections indicate that by 2044, the daily average will peak at more than 135,000 vehicles, the state highway administration said.
Widening the corridor will improve safety, ease congestion and strengthen the flow of people and commerce across our state, county officials said.
The project is also intended to relieve traffic on I-97, as well as reduce diversion onto adjacent arterials such as Maryland Routes 2 and 3, the state highway administration said.
The project includes:
- Adding a travel lane in each direction on I-97 from U.S. Routes 50\301 to Maryland Routes 32\3.
- Improving the I-97 northbound bridge over Defense Highway, as well as the I-97 bridges over Crownsville Road.
- Installing new stormwater management facilities.
