Please note: The westbound Duke St lanes are shifted to the left along the bridge over I-395 until spring 2023.

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

The improvements include:

  • Replacing the concrete bridge deck and beams
  • Upgrading the westbound sidewalk to a shared-use path
  • Widening the eastbound sidewalk

In August 2022, the Duke Street concrete roadway was repaired just west and east of I-395.

The bridge carries about 47,000 vehicles a day.

Estimated Costs
Preliminary Engineering - $1.4 million
Construction - $15.1 million
Total - $16.5 million

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


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