State plans 2-year, $10m project to rebuild Cambridge Street bridge over I-90 in Allston

The state is planning a two-year, $10-million project to completely rebuild a bridge that carries Cambridge Street over the Massachusetts Turnpike and commuter rail tracks in Allston

For an estimated 18 months of the construction period, Cambridge Street will have just one eastbound traffic lane and two westbound travel lanes open between the project limits

For a six-month phase of construction, Linden Street between Cambridge Street and Pratt Street will become a one-way southbound, reversing its current configuration as a one-way street northbound. During that period, northbound traffic on Linden Street will be rerouted to Harvard Avenue.

The project will also include foundation repairs and patching of the Franklin Street pedestrian bridge that runs from Cambridge Street, over the turnpike, and connects to Lincoln Street. The pedestrian bridge will be closed for about six weeks while areas of the deck are repaired. Pedestrians will be directed to the stairs and ramps and the east end of Cambridge Street
