This project will replace the superstructures of the six I-90 bridges (east and westbound) over Flanders Road, Parkerville Road, and Woodland Road. The two bridges over Cordaville Road will be replaced entirely.
Resurfacing of I-90 and replacement of the median barrier and guardrails will take place along the entire length of the 3.3-mile project corridor.
For this project, MassDOT has utilized design-build project delivery where one entity is responsible for both the design and construction. This alternative contracting method not only helps reduce the time needed to carry out the project, but also promotes collaboration between the engineers, contractor, and MassDOT staff.
MassDOT is replacing these bridges before the start of the adjacent I-90/I-495 Interchange Reconstruction Project to avoid overlapping traffic impacts. Delaying these replacements until after the I-90/I-495 project would result in continued deterioration causing more extensive and costly repairs. The project team will also coordinate closely with other MassDOT projects, including the I-90 Allston Brighton Interchange, I-90 Exit Renumbering, and Fruit Street bridge replacement.
Using Accelerated Bridge Construction (ABC) methods and weekend traffic crossovers will allow for safer and more efficient construction. Conventional bridge replacements would take approximately 3 years and increase traffic congestion.
During the summer of 2021, MassDOT will replace these structures over eight separate weekends. Utilizing ABC methods and replacing one bridge at a time will limit impacts to local traffic. During these weekends:
Beginning Friday night, one direction of I-90 will close.
That direction of traffic will be shifted to the opposite side of the highway using median crossovers.
On the open side of the highway, I-90 will consist of two lanes in each direction (east & westbound) separated by temporary barrier.
Traffic will be shifted back and I-90 will open to three lanes in each direction by the following Monday morning.
To ensure public safety during weekend bridge work, we will close the local roadway below the bridge to traffic. A signed detour route will be in place and advance notification will be provided. Please sign up to receive email updates.
MassDOT’s goal is to reduce delays for drivers to the fullest extent possible. MassDOT will work with the design-build contractor to determine acceptable times for lane reductions. No work will take place on holiday weekends and the July 4th holiday period.
