Construction on the Diamond No.1 bridge is scheduled to begin the first week of July and construction of the Wildcat No. 2 bridge is slated to start the last week of July.
Both bridges will be rebuilt one half at a time, with one lane of traffic remaining open alternating in each direction controlled by temporary signals, PennDOT said.
Located just north and south of the intersection between S.R. 861 and Flick Road, the crossings were built in 1958 and both average 923 vehicles a day. The work for both bridges is expected to be completed by mid-November, according to PennDOT.
The bridge replacements are part of the Rapid Bridge Replacement Project, a Public-Private Partnership between PennDOT and Plenary Walsh Keystone Partners.
