Bunch of HATERS !!!

Groton Bridge

They just don't build them like they used to. Why would you replace a bascule bridge with a vertical lift bridge? Waddell and Harrington used to build some nice lift bridges back in the day, but even those bridges are extremely slow to raise and lower compared to a well-built bascule bridge (like the one demolished and replaced here).

This bridge and the Gold Star Mem. Bridge were featured in a scene from the movie "Down Periscope."
