Interstate 91 Viaduct Rehabilitation Project

About This Project

The I-91 Viaduct Rehabilitation Project will replace the existing deck of the I-91 viaduct, an elevated structure in Springfield, Massachusetts. The project will progress on an accelerated schedule to minimize traffic impacts and reduce construction duration. Once completed, the I-91 Viaduct Rehabilitation Project will increase safety and accessibility on this busy interstate, reduce annual maintenance costs, and ensure long-term service. MassDOT signed a $148 million contract with the Joint Venture of White-Schiavone (JV) in May 2015. The project will receive 80% of its funding from the Federal Highway Administration and 20% from the Commonwealth.

Work has begun to prepare the viaduct for the traffic shifts required for construction, along with repairs and improvements to surface streets which will see an increase in local traffic. The next major phase of construction begins in winter 2015/2016 and requires lane and ramp closures on the I-91 viaduct, with associated detour routes. Traffic is scheduled to be fully restored on the viaduct in late fall 2017, with the final contract completion planned for February 2019.

The contractor will implement a Real Time Traffic Management (RTTM) system to monitor and collect traffic data along various roadways within the project’s impact area.  Real-time travel information will be provided to the project team and the traveling public based on the data collected.

MassDOT will provide regular updates on traffic changes. For more information, review the project overview, browse project documents, and learn more about the construction plans.

Traffic Management

This first phase includes utility work, intersection improvements and bridge deck repairs with nightly lane restrictions.

On Sunday through Thursday nights through fall 2015, one or two lanes on I-91 north and/or southbound will be closed to allow the Contractor to mill out the existing pavement and repair the concrete deck. All lanes will reopen by 5:00 AM the next morning. For additional details, review the Traffic Management page.

What's New

MassDOT’s contractor will begin demolishing the I-91 Viaduct’s concrete bridge deck the week of February 8. To learn about demolition activities, visit the Construction page. Multiple lane and road closures are planned on I-91 and local roads in Springfield. For more details, visit the Traffic page.

MassDOT warns travelers of significant delays expected on I-91 South on Sunday afternoons this winter due to seasonal travel from northern destinations.
