image002-8The Massachusetts Department of Transportation has announced that the Commonwealth Avenue Bridge Project “dry run” of traffic equipment logistics on I-90 (the Massachusetts Turnpike) in Boston that reduced traffic to two lanes in each direction and required varying on and off-ramp closures was successfully completed this morning at approximately 3:30 a.m. All lane restrictions and ramp closures associated with the dry run have been restored and there are now four lanes of traffic flowing in each direction on I-90 east and westbound in Boston.

“We are pleased to have completed this dry run ahead of schedule and successfully tested the traffic setup equipment on I-90 that will be used for the Commonwealth Avenue Bridge Replacement Project work this summer,” said Highway Administrator Jonathan Gulliver. “Our project team deployed the necessary logistics on Friday evening, monitored the configuration and traffic pattern during the overnight and Saturday morning hours, and we were able to complete our work ahead of schedule due to the support of motorists and the planning and coordination of our engineers, work crews, and law enforcement.”

The upcoming intensive construction operations when MassDOT demolishes and replaces the westbound side of the Commonwealth Avenue Bridge this summer are scheduled to take place over 15 ½ days from Thursday, July 26, through Saturday, August 11. These types of construction operations and the corresponding travel impacts were used during a 20 day period in summer 2017 when MassDOT successfully demolished and replaced the eastbound side of the bridge as well as MBTA Green Line infrastructure.

Between July 26 and August 11, there will be significant service impacts to all modes of transportation in the Boston University/Saint Paul Street neighborhood of Boston along Commonwealth Avenue, including MBTA bus, commuter rail and Amtrak customers, vehicles along Commonwealth Avenue and the Boston University Bridge, and traffic on I-90 (the Massachusetts Turnpike).

Detours and transit shuttles will be necessary for some station stops on the MBTA’s Green Line B Branch, MBTA Bus Routes CT2 and 47, the MBTA Worcester Commuter Rail Line, and Amtrak’s Lake Shore Limited route. The impacts on all modes of transportation are a necessary part of having the MassDOT contractor work continuous shifts 24 hours a day and utilize Accelerated Bridge Construction techniques in order to reduce overall construction duration, minimize the impact on the traveling public and local community, and improve safety.
