The left lanes in both Eastbound and Westbound directions on I-90 from west of the Prudential tunnel to the Commonwealth Avenue Bridge are closed to traffic in order to create work zones for substructure rehabilitation work and to reconstruct the I-90 median. Closure of the right lanes in both directions to complete the substructure work for the Commonwealth Avenue Bridge project will follow the reopening of the left lanes. To ensure safe merging distance on I-90 Eastbound leading up to the lane closure, one lane of the on-ramp is closed from Interchange 20.
Three lanes of traffic will be maintained in each direction on I-90 Eastbound and Westbound during peak hours. Short-term nighttime and weekend closures of an additional lane on I-90 Eastbound and Westbound will take place nightly.
Work to be performed throughout this project will include rehabilitation of the east and west abutments, as well as major rehabilitation of the east and west piers and reconstruction of the I-90 median.
Work to date in August includes installation of temporary barrier and digging test pits associated with the construction of the new foundation for the Commonwealth Avenue bridge. Additional work includes removal of guardrail and median along with pavement saw-cutting adjacent to the temporary barrier, excavation of the existing asphalt down to the top of the footing of the existing piers as shown above, and preparation for installation of the temporary earth support needed for the shoring towers that will be used to support the bridge deck.
Work in the next few weeks will include installation of earth support on the eastbound side of I-90. The current work prepares the subsurface for the shoring towers and a jacking system to keep the bridge deck in place to allow foundation work to be done without affecting the street above. Expect to see the shoring and jacking system set up in the closed travel lane.
The project-required lane closures causing congestion in the I-90 Allston/Brighton tolls area and at the Interchange 20 on-ramp to I-90 eastbound are the result of traffic management plans that take into account area constraints with the physical, available right-of-way and close proximity to the commuter rail lines. The closures allow the project to be completed safely and on schedule. MassDOT will continue to monitor traffic impacts and make adjustments as necessary that continue to ensure safe travel in the work area.
The project will be ongoing throughout the next twelve months leading to the replacement of the Commonwealth Avenue Bridge deck over I-90 which is scheduled to begin in late 2015.
