Heroes Tunnel Improvements

closed

The Heroes Tunnel is located along the Wilbur Cross Parkway (Route 15) in the Town of Woodbridge and the City of New Haven, near the Town of Hamden border.  The Heroes Tunnel is a 1,200-foot long tunnel, which passes through West Rock Ridge in New Haven and Woodbridge.  The existing tunnel was constructed between spring 1948 and fall 1949 and consists of two 28-foot wide by 19-foot high barrels with horseshoe cross-sections.  The northbound and southbound barrels of the tunnel consist of two 11-foot wide travel lanes with 6-inch shoulders and a 26-inch wide raised maintenance walk on each side. The centerlines of the barrels are approximatly 63 feet apart. It is the only tunnel to pass beneath a natural land feature in the State of Connecticut and is eligible for listing on both the National and State Registers of Historic Places. The Heroes Tunnel Project limits encompass the 1,200-foot tunnel and extend approximately 2,000 feet from the tunnel portals, in both the northbound and southbound directions. The proposed project would address structural deficiencies, operational obsolescence, and capacity demand at Heroes Tunnel.
