Rehabilitation of East Rock Road Bridge

Rehabilitating a 100-year-old Bridge

New Haven, Connecticut

The bridge’s 112-year-old arches were originally constructed around 1900 and the bridge holds significant historic importance to the community.

Our design adhered to the Connecticut Commission on Culture and Tourism’s recommended design guidelines, including an ornamental bridge rail system and period style lighting.

The 84-foot-long single-span steel deck arch bridge carries two lanes of vehicular traffic over a 20-foot roadway and has two five-foot-wide pedestrian sidewalks.

We designed the rehabilitation of the East Rock Road bridge over Mill River in New Haven, Connecticut. Our design adhered to the Connecticut Commission on Culture and Tourism's recommended design guidelines, making sure the reuse of the historic bridge will continue. The project consisted of deck replacement, superstructure steel repairs, and minor modifications and repairs to the substructures to improve the condition of the bridge. The existing bridge was removed and transported to a shop in Boston where it was completely dismantled, blast cleaned, strengthened, and painted. The strengthened bridge elements were then transported back to the site and re-erected at its current location.

We successfully obtained both an exception from the Federal Highway Administration and an approval from the Connecticut Commission on Culture and Tourism to maintain the existing 20-foot roadway width since our design facilitated historic preservation and reuse of existing bridge elements.
