Indiana State Road 912

State Road 912 (SR 912), known along its entire length as Cline Avenue, is a freeway north of the combined Interstate 80/I-94/U.S.

On April 15, 1982, part of a ramp under construction collapsed during concrete pouring operations near the Indiana Harbor and Ship Canal, killing fourteen highway workers and injuring eighteen more.

After crossing the bridge, the portion ahead serves several of the steel mills (many now owned by Cleveland-Cliffs) and the casino in East Chicago.

[6] On April 15, 1982, 14 workers were killed and 18 injured when falsework beneath a ramp failed during a concrete pour.

Workers on Unit 4 were crushed to death when the section flipped and landed upside-down while descending due to tension in the cables.

[6] Investigators from the National Bureau of Standards for the Occupational Safety and Health Administration (OSHA) discovered several errors that caused the collapse of the bridge section.

The failure of the concrete pad, built too thinly, led to another finding; one-inch (2.5 cm) bolts that were supposed to connect key stringers to cross-beams instead were replaced with frictional clips, but investigators did not find any documentation that supported this substitution.

[6] Lawsuits against companies involved in building the ramp were settled out of court, as no single party could be found to explain the discrepancies.

[6][9] During the middle of 2006, numerous drivers reported possible attacks by a sniper on the eastern portion of Cline Avenue.

[5] On April 15, 2010, INDOT announced its plan to demolish the bridge and reroute traffic via Riley and Dickey roads.

The cost of the bridge is expected to be $150–250 million to complete depending on whether steel beams from the original structure can be reused.

[24] The bridge owners took legal action against the Great American Insurance Group for $105 million in August 2020.

After that, toll collections began at a discount; regular price was implemented starting in the beginning of March.
