The nearly 3-million lb. center lift span was floated in on barges across the Piscataqua River between 10 a.m. and noon and positioned for the float in. On Oct. 18, between 6 a.m. and 9 a.m. the rising tide lifted the span to clear the bearings. Between 9 a.m. and noon the lift span was put into position over the bearings. At 1:45 p.m. the outgoing tide lowered the lift span onto the bearings. Once resting on the bearings, the barge was pushed to the state pier. Adequate clearance to remove the barge from under the lift span occurred at approximately 3:45 p.m. Once complete and placed in-service, the new lift span will weigh approximately 4 million lbs. or 2,000 tons. The new bridge alignment will improve marine navigation by increasing the navigational clearance

Two hundred foot tall precast concrete towers will support the 300-ft. long streamlined structural steel box girder lift span. There are eight operating ropes (steel cables) that pull the counterweights up and down to lift and lower the bridge. If laid end to end these

bridges that Maryland Gov. Larry Hogan committed to addressing. The $7.3 million project started in July and is expected to be complete by the fall of 2019. MDOT SHA’s contractor is Six-M Company Inc. of Delta, Pa. According to Charlie Gischlar, public information officer of MDOT SHA, the 62-year-old-bridge is safe, but is rated “structurally deficient” and has outlived its service life. “MDOT SHA is installing a temporary bridge for motorists and pedestrians to use during construction and reduce impacts to the environment and nearby residents,” Gischlar see BRIDGE page 104
