Here are a pair of photos of the long gone Belle Isle Bridge Approach in Detroit. The original bridge was built in 1889, and destroyed in a fire in 1915. In 1923, the current bridge was built to link the mainland to the island. When it opened there was a nifty underground approach when headed south on East Grand Boulevard, that let you bypass the intersection with East Jefferson Ave.
I’m not sure when it happened but, somewhere along the line it was filled in.
