The Pennsylvania Department of Transportation announced Tuesday that the bridge that carries Pa. 233 over Rocky Mountain Creek south of Caledonia State Park in Greene Township, Franklin County, will be closed for a superstructure replacement project.
PennDOT said the Pa. 233 bridge over Rocky Mountain Creek will be closed to through traffic for up to 81 days. Until then, a short detour will be in place using an unnamed side road and U.S. 30. A temporary traffic signal will be in place on U.S. 30 at the intersection with the unnamed road.
This portion of Pa. 233, locally known as Rocky Mountain Road, averages more than 1,300 vehicles daily.
PennDOT awarded the $569,000 contract on Dec. 20 to Redrock Construction Inc. of Lewistown, Pa. Work includes replacing the existing 102-year-old three-span concrete arch structure with a new two-span cast-in-place reinforced concrete slab; pavement work; new guiderails; signs and pavement markings.
The existing bridge was built in 1917 and has a posted 15-ton weight limit. Once it is replaced and the road is restored to traffic, the weight limit will be removed from the new bridge.
Milling and paving work might be conducted after the bridge is opened under short-term single-lane alternating traffic patterns. Work is scheduled to be completed in October 2020.
The project will be in accordance with Centers for Disease Control and Prevention and Pennsylvania Department of Health guidance, as well as a project-specific COVID-19 safety plan, which will include protocols for social distancing, use of face coverings, personal and job-site cleaning protocols, management of entries to the job site, and relevant training.
