Commuters will be somewhat inconvenienced over the weekend while the Baltimore Harbor Tunnel, on northbound Interstate-895, is closed for construction.

According to a press release from the Maryland Transportation Authority (MDTA), the northbound bore of the Baltimore Harbor Tunnel will close at 8:30 p.m. on Jan. 30 for repairs. These will consist of performing concrete pouring operations and manhole adjustments. The closure is part of the MDTA’s three-year, $189 million I-895 Bridge Project to replace the 60-year-old bridge and Holabird Avenue exit ramp north of the Harbor Tunnel, and to rehabilitate the Harbor Tunnel. The project began in April 2018 and is expected to be completed in summer 2021, according to the release.

Weather permitting, the northbound bore will reopen at 4:30 a.m. on Feb. 3. In the meantime, commuters are encouraged to Key Bridge on Interstate-695 and the Fort McHenry Tunnel on Interstate-95 as alternate routes.
