Work should begin early next month on a project to replace and repair a bridge on Md. 355 just below the Frederick County border in Hyattstown.
Some initial work has already been done for the project on the bridge over Little Bennett Creek, but people should notice activity there after the new year, said Charlie Gischlar, a spokesman for the State Highway Administration.
The $8.3 million project is expected to be finished in the fall of 2020.
The bridge, built in 1925, is one of the 69 structurally deficient bridges in the state that have been a focus of Gov. Larry Hogan’s since he took office.
Although it has been deemed structurally deficient, the bridge is still safe for drivers to use.
“It’s safe, but it’s outlived its useful life,” Gischlar said.
The project is being done by Concrete General, of Gaithersburg.
Workers will build a temporary bridge to allow drivers to use the road while the work is being done.
That section of Md. 355 is used by about 8,200 vehicles each day, according to SHA.
The work will also include restoring about 900 feet of Little Bennett Creek to prevent erosion of the stream bank.
When it’s finished, the new bridge will be about 3 feet higher than the current one.
The higher bridge will help allow more water to move under the bridge, helping limit erosion along the banks, Gischlar said.
While repairs have been made to the bridge in the past, it eventually became more economically feasible to replace it, he said.
The building of the temporary bridge will likely lead to single lanes being closed at various times during off-peak travel hours.
The project is one of three being done on Md. 355 in Frederick and northern Montgomery counties. The others include a new bridge over the CSX tracks near Monocacy National Battlefield, and at Md. 355 over Bennett Creek, near Urbana.
