An engineering study (The New Haven Harbor Access Study) has been completed for I-95 between Canal Dock Road and Interchange 45 (Route 10) in the Long Wharf/Sargent Drive area.

The study addressed various I-95 roadway configurations and improved Interchange 46 configurations that are compatible with the I-95/I-91/Route 34 Interchange design included in the I-95 NHHC Corridor Improvement Program. The study also assessed measures to improve pedestrian and vehicle access to the New Haven Harbor waterfront at Long Wharf Park and Bayview Park.

Three alternatives were developed, including the depression of I-95 through that area, elevation of the roadway, and widening I-95 at its current location (“at grade”). Each alternative includes the addition of one travel lane in each direction and full inside and outside shoulders. The “at grade” alternative is being studied further through a separate environmental evaluation, the Long Wharf Environmental Assessment, currently underway.
