A planned $890,000 realignment of Cleveland’s Inner Belt Bridge over the Cuyahoga River has been postponed because engineers still need to confirm some calculations, according to Jocelyn Clemings, an Ohio Dept. of Transportation spokeswoman. The 4-in. realignment, which officials hope will occur within the next few weeks, will entail raising the west end of the 70-million-ton bridge off its piers, setting it down on lubricated plates and jacking it to the west to free up an expansion joint. The bridge is similar in design to the Interstate 35 bridge that collapsed in 2007 in Minneapolis. Photo: AP / Wideworld
