Carroll Ave. Bascule Bridge in Operation

In 1988 the C&NW was still an independent railroad with headquarters in Chicago. We're looking south here across the C&NW bascule bridge used to reach Navy Pier towards the headquarters building on Canal St. in the distance. Note the C&NW logos.
Yes, the picture is overexposed due to light leaking into the camera, but it's still a rare shot of a C&NW tower operator working the levers to lower the bridge over the North Branch of the Chicago River just south of Kinzie St. in 1988.
