Comm Ave Replacement

What's New

MassDOT will implement the 2018 construction shutdown from Thursday, July 26, 2018, to Saturday, August 11, 2018, to replace the westbound side of the Commonwealth Avenue Bridge. The following roads and facilities will be impacted: Commonwealth Avenue between Brighton Avenue/Packard’s Corner and Kenmore Square, the Boston University (BU) Bridge, I-90 (Mass Pike), the MBTA Green B Line, Bus Routes 47 and CT2, Commuter Rail Worcester Line, and Amtrak's Lake Shore Limited route.

MassDOT is partnering with the City of Boston to provide an additional temporary Blue Bikes station at Silber Way on Commonwealth Ave during the construction period.
