Repairs will soon begin on a bridge across the Monocacy River in southern Frederick County, although the work won’t be very visible for a few weeks.
The bridge on Md. 28 south of Monocacy National Battlefield, near the border of Frederick and Montgomery counties, will have a traffic signal set up at each end while the work, which is expected to be finished by summer 2019, is being done, State Highway Administration spokesman Charlie Gischlar said Tuesday.
The work will include replacing the riding surface known as the bridge deck, putting in a service road to maintain access to the river and park area, replacing parts of the steel truss bridge, replacing concrete bridge piers, removing debris that has built up under the bridge, and cleaning and painting the bridge’s metal sections.
Much of the initial work will involve preparing for the project, and people likely won’t actually see much being done until August, Gischlar said.
The bridge was built in 1931, and is crossed by about 9,300 vehicles per day, according to SHA.
Gov. Larry Hogan (R) made a point when he took office to address all of the 69 bridges in the state that had been labeled structurally deficient, and as of July all 69 have been replaced, rehabilitated, or had jobs advertised for construction.
“All of them are in some form of active work, or will be,” Gischlar said.
Twelve of the bridges are in Frederick County, and all have been addressed, he said.
“Structurally deficient” doesn’t mean that a bridge is in imminent danger of falling, but that some element, often the riding surface, has deteriorated.
The 12 bridges in Frederick County were the most of any county in the state, and along with the Md. 28 bridge included bridges on Interstate 270, Md. 355, U.S. 15, U.S. 40, Md. 77, Md. 140, Md. 194, Md. 478 and Md. 464.
