Status, construction and traffic management: I-495/I-90 interchange improvements

Improving safety and addressing traffic conditions at the interchange of I-495 and I-90

Status

Project construction continues on the I-495/I-90 Improvements project. The following activities are underway:

Fruit Street Bridge:

  • Phase 1 of the construction of the Fruit Street Bridge is scheduled to be complete in the Spring of 2024. From there, the team will begin traffic relocation work following the completion of utility work being undertaken by third parties. Following the implementation of traffic relocation, Phase 2 of the Fruit Street Bridge construction process will continue.

I-495 Construction:

  • The construction of the new median bridge on I-495 is schedule to be completed in Summer 2024. Looking ahead, I-495 southbound traffic will be relocated to a temporary median crossover during Summer 2024 to enable the project team to commence construction activities on I-495, including shoulder work on I-495 southbound.

Ramp WN:

  • The project team has completed the installation of a temporary trestle structure at ramp WN while foundation work at the ramp is ongoing. Looking ahead, substructure work is scheduled to begin during Spring 2024 and requisite steel erection work is scheduled to begin in Autumn 2024.

I-90 Construction:

  • The project team is scheduled to begin bridge construction at Whitehall Brook along the eastbound shoulder imminently. Additionally, the team is continuing to work on the I-90 bridge over MBTA/CSX/Amtrak rail tracks and is continuing to widen the eastbound shoulder. Work on the westbound off ramp (ramp WS) is expected to continue, while requisite steel erection work is schedule to begin in Autumn 2024.

Old Toll Plaza:

  • The project team is continuing to work on ramp ES at the old toll plaza while the team is scheduled to complete the installation of the culvert and retaining wall in Spring 2024. The team will continue the installation of the barrier and road box throughout Summer 2024 and a new ramp (I-90 eastbound to I-495 southbound) is scheduled to open in Summer 2024.

Ramp SE:

  • The project team will commence the construction of a retaining wall during Spring 2024 and the installation of the barrier and road box will continue throughout Summer 2024.

Construction activities are weather dependent and subject to change without notice.

Traffic and Staging Considerations

The project will involve complete replacement of the interchange. To avoid traffic impacts, the project will:

  • Maintain 3 lanes on mainlines, except for short-term closures during approved off-peak hours
  • Maintain all ramp connections between I-90 and I-495, including along temporary alignments
  • Maintain proper signage and markings
  • Provide temporary roadway lighting along ramps for safe nighttime travel
  • Provision of safe construction access/egress
  • Maintain resident and local business access/egress
