The I-91 Viaduct Rehabilitation Project is replacing the existing deck of the I-91 viaduct, an elevated structure in Springfield, Massachusetts. The project is progressing 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.
In December 2015, MassDOT began major construction and closed the inner lanes and several ramps on the I-91 viaduct. This phase of construction, Stage 1B, will continue through winter 2016. The contractor began placing sections of the I-91 northbound deck in May 2016 and completed the work in July 2016. After the contractor replaces the northbound barrier, it will start placing sections of the I-91 southbound deck. The contractor anticipates fully restoring traffic on I-91 and I-291 in spring 2018.
MassDOT and the contractor are continually monitoring and collecting traffic data along various roadways within the project's impact area. The team is making adjustments to traffic signals, intersections, lane markings, and other infrastructure on I-91 and local roads, as needed.
MassDOT provides regular updates on traffic changes. For more information, review the project overview, browse project documents, and learn more about the construction plans.
