Construction workers in Cleveland face a Herculean task -- moving the 70-million-ton Inner Belt Bridge 4 inches to the west, officials say.

The west end of the span, which carries Interstate 90 over the Cuyahoga River, will be raised off its piers, set on greased plates and then jacked the inches necessary to get it realigned properly, The Plain Dealer reported Wednesday. Once in place, the bridge will be re-bolted to the piers.

The project is to start Friday night and take several days to complete. Most of the work is to be done at night so traffic interruptions should be minimized, officials say.
