New cranes heading to Baltimore to close bridges

Massive new cargo cranes heading to the Port of Baltimore will stop traffic on two bridges along the way.

The Maryland Transportation Authority says Coast Guard and transportation officials were worried that motorists would stop to watch or cause accidents. The four cranes are scheduled to pass under the Bay Bridge near Annapolis and the Key Bridge near Baltimore on Wednesday afternoon.

The Bay Bridge will be closed for about 40 minutes beginning at 1:15 p.m. and the Key Bridge will be closed for about 20 minutes at 3:15 p.m. Authorities say those times could change.

The four cranes are heading to the Seagirt Marine Terminal where they will be able to handle new, larger ships expected to use the Panama Canal once a widening project is finished in 2014.
