The Massachusetts Turnpike will be reduced from four to three lanes in each direction beginning Friday night as part of the Commonwealth Avenue bridge replacement project.
The lane closures will stretch from the Allston/Brighton interchange to the Beacon Street Overpass in Boston. The closures take effect at 9 p.m. and are expected to continue through Aug. 28.
The move is necessary to allow for the replacement of the Commonwealth Avenue Bridge that runs over the highway. Massachusetts Department of Transportation crews will use the unused lanes to build a crane and place equipment in the median.
Delays are expected, and highway officials said drivers should consider alternative modes of transportation, including public transit. The commuter rail in this area is also expected to be impacted by this construction later in July and August.

MassDOT crews will also be working in the area of the former Allston/Brighton toll plaza beginning during the off-peak, overnight hours on Friday as part of the continued toll demolition and road construction project. These lane reductions are expected to be completed by 7 a.m. on Sunday.
