The Cline Avenue Bridge carries Cline Avenue over the Indiana Harbor Canal in East Chicago, Indiana. The current bridge opened in 2020, replacing a 1983 crossing that was closed in 2009 because of severe deterioration and later demolished, though some remnants remain. The site is also remembered for the 1982 construction collapse that killed 14 workers, one of the worst bridge disasters in Indiana history.

I've posted more photos and a history of the 1983 and 2020 bridges here.

Tunnel No. 6 was located along the Pennsylvania Railroad's Panhandle Line in eastern Ohio. I've posted more photos of this tunnel and other aspects of the railroad here.
