This used to be called West Rock Tunnel. I know this as I have been there many times in the past. As I was passing through a few days ago I saw the name had changed to «Hero’s Tunnel», in honor of the heros from the Sept 11, 2001 days. They are not singling out one type of hero, rather all who were heros that day and all the days that followed. This is a short tunnel, and it two different tubes one for each direction. Its just outside of New Haven, CT on Rt 15. Its been open since 1949 and was one of the first to pass under a land feature in New England. As you go North/South along Rt 15, this is a nice tunnel, and its short, for those who don’t like tunnels, you can«see the light» at the end from the very start. 1275
