image005The Massachusetts Department of Transportation has announced that its accelerated replacement of the Route 3 northbound bridge in Braintree was completed at approximately 11:30 p.m. on Sunday, September 24, several hours ahead of schedule as work was expected to be completed by 5 a.m., Monday, September 25.

Accelerated operations began at 10 p.m., on Friday, September 22, and have meant ramp closures, lane reductions, and detours throughout the area as crews worked 24/7 to demolish the existing bridge, put in place prefabricated steel beams, concrete deck panels, and mill and pave the roadway. MassDOT will next replace the Route 3 southbound bridge in Braintree and implement similar lane closures and traffic detours during the weekend of October 13-16.

“We are pleased that our accelerated work to replace the bridge on Route 3 north in Braintree has been completed several hours ahead of schedule, and our detours and lane closures have been removed so that traffic can flow in the normal configuration,” said Acting Highway Administrator Jonathan Gulliver. “We were able to replace this bridge quicker than expected due in part to the cooperation of the traveling public and the around-the-clock work of our crews and contractors, and we look forward to replacing the bridge on Route 3 south during an upcoming weekend in October.”

For this $6.3 million project, crews are using accelerated methods on two weekends to replace two bridges that carry Route 3 over an I-93 ramp just south of the Braintree split. The full hours for the upcoming traffic impacts in October are as follows:

  • Replacing the bridge on Route 3 southbound: 10 p.m., Friday October 13, through 5 a.m., Monday, October 16.

The lane closures and detours for the weekend in October are as follows:

  • A lane reduction on Route 3 north and southbound in the area of Exit 19.
  • A detour for traffic that is seeking use Exit 19 off of I-93 and access the Burgin Parkway. All lanes on I-93 north and southbound will remain open during these times and the detour route will utilize Exit 18 and local roadways.
  • A detour for local traffic on Washington Street that is seeking to use the on-ramp to access I-93. All lanes on I-93 north and southbound will remain open during these times and the detour route will utilize local roadways.

In order to accommodate construction operations, crews are implementing “crossovers” so that all traffic is diverted away from these bridges and shifted onto the adjacent side of the roadway and a nearby ramp. Traffic using nearby ramps is also being detoured, and law enforcement details and variable messaging boards are being put in place in order to guide drivers during these times.

The full scope of work for this significant construction project has been explained to the public, elected officials and the media on many occasions.  Preparation and work-related activities have been ongoing since the spring.  The Route 3 bridge replacement activities involve crews putting in place simple span welded steel plate girders, composite concrete decks as well as modified beam sets in order to complete these accelerated operations in just two 55-hour periods over two weekends. All work associated with the project is expected to be completed by fall 2018 as activities to be completed in 2018 include removing the crossovers, utility operations, drainage work, landscaping, and minor finishing work.

 

Drivers should be mindful of potential traffic impacts and should devote their full attention to driving through these active construction zones as MassDOT works to replace the bridges on this regionally significant roadway.
