Aging Charles River rail bridge closes for repairs

Serves as freight link across Charles

The graffiti-covered railroad span that threads diagonally under the Boston University Bridge will be closed to most train traffic for two weeks, after an inspection found some of its crossbeams need to be replaced.

Many people are unaware that the 90-year-old railroad bridge across the Charles River is in use at all, but it is a critical piece of transportation infrastructure. It is part of the little known Grand Junction Railroad, which starts in Brighton and wends its way through Cambridge, Somerville, Everett, and Chelsea, connecting train lines that go to North Station with the ones that lead to South Station.
