Welcome to the webpage for Project 0061-0156, Route 15 Interchange 51 Improvements in Hamden and North Haven.
A public informational meeting for the project will be held on Tuesday, September 15, 2026, at the at 6:00 p.m. at the Hamden Government Center, 3rd Floor Conference Room, located at 2750 Dixwell Avenue in Hamden. The meeting facility is ADA accessible.
An open forum for individual discussions with CTDOT officials will begin at 6:00 p.m. and the formal presentation will begin at 6:30 p.m. This meeting aims to inform the community about the proposed project, gather feedback, and answer any questions.
The purpose of this project is to improve safety at the Route 15 interchange 51 ramps and improve mobility for all roadway users along Whitney Avenue. This project is needed because of the high number of front-to-rear crashes at this interchange due to the stop-controlled on-ramps. On Whitney Avenue, inadequate pedestrian facilities create potentially hazardous conditions.
Proposed improvements on Route 15 include the removal of stop controls and the addition of acceleration and deceleration lanes, as well as the addition of signals and pedestrian crossings at the ramp intersections and the addition of sidewalks on Whitney Avenue.
Right-of-way impacts associated with the proposed improvements will include a partial sliver acquisition to accommodate a turn lane and sidewalk reconstruction. Temporary easements and rights to grade are also anticipated for sidewalk construction, retaining wall modifications, and guiderail installation.
Construction is anticipated to begin spring 2028 subject to availability of funding, acquisition of rights of way, and approval of permits. The estimated construction cost for this project is approximately $32 million. This project is anticipated to be undertaken with 80% federal funds and 20% state funds.
