The replacement of a small bridge on U.S. 11 in Antrim Township will cause big traffic issues next year.
The bridge over a tributary to the Conococheague Creek is located near World Kitchen south of the Borough of Greencastle, between Commerce Avenue and Washington Street.
That stretch of U.S. 11 — traveled by about 12,800 vehicles a day — will be shut down for one to two months during the replacement, according to a Pennsylvania Department of Transportation spokesman.
Engineering plans, on display at the Antrim Township municipal building through March 29, show a 8.4-mile detour route using Interstate 81 between Exit 3 and Exit 10 at Marion.
"The existing bridge is a concrete slab structure that was placed in 1936. The structure has deteriorated to the point of needing to be replaced," according to PennDOT.
The bid opening will probably take place in March 2020, with construction starting in May.
"Crews will excavate and remove the existing slab structure, install the proposed pre-cast concrete box culvert, and reconstruct the roadway and pavement," according to PennDOT. "The construction cost should be under $1 million."
