This project will rehabilitate the Duke Street (Route 236) bridge over I-395. The bridge was built in 1965.

The planned improvements include:

  • New concrete bridge deck and steel beams
  • Replacing the westbound sidewalk with a shared-use path
  • Widening the eastbound sidewalk

At the interchange, Duke Street averages up to 55,000 vehicles a day and I-395 averages up to 181,000.

Estimated Costs
Preliminary Engineering - $1.3 million
Construction - $15.7 million
Total - $17 million

The project is being financed with federal and state funding, including State of Good Repair funds used for maintenance of structures and bridges.


This project will improve safety for drivers, bicyclists and pedestrians and extend the overall life of the bridge.
