The Maryland Department of Transportation is advising drivers to avoid I-895 due to construction unless they need to reach one of its exits. The state recommends drivers use Interstate 95 or the I-695 beltway as an alternative to I-895 where possible. The project is scheduled to be completed in 2021.

The northbound lanes will close from the tunnel to O’Donnell Street, and the two southbound lanes will convert to two-way traffic through spring 2020. Once the northbound span has been rebuilt, it will carry two-way traffic through spring 2021 while the southbound span is replaced.

The project also includes $28 million in repairs and upgrades to the Harbor Tunnel, which will be completed during 60-day, continuous closures of each of its bores: the northbound one in spring 2019, and the southbound in spring 2020. Two-way traffic will operate in the opposite bore during each closure.
