Please note: The northbound I-395 general purpose lanes are shifted to the right at Duke Street (Route 236) until summer 2022.

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

The planned improvements include:

  • Replacing the concrete bridge deck and beams
  • Upgrading the westbound sidewalk to 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 based on 2019 data.

Estimated Costs
Preliminary Engineering - $1.3 million
Construction - $15.4 million
Total - $16.7 million

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


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