CLEVELAND, Ohio -- Steel trusses cutaway from the old 1959 Innerbelt Bridge made a big splash in the Cuyahoga River as construction crews began demolition of the span over the waterway.

The river will be closed through 6 a.m. Friday morning to remove the span. There could be additional short-term closures in the coming weeks if they do not finish this week.

Engineers from Trumbull-Great Lakes-Ruhlin designed a plan for the removal of each truss so the span remains stable during demolition.

The steel trusses that fall into the Cuyahoga are fished out by cranes and placed on a barge. Some pieces of the span will be lowered to the ground.

This is the second of four spans being manually removed. Once they are down, the remaining five spans of the bridge will be brought down by controlled explosions in July.

Construction of the second span of the George V. Voinovich Bridge will begin once the demolition of the old one is complete.
