Construction to replace the bridge on Middletown Road that spans Interstate 83 in Parkton will begin on Sept. 5, according to the State Highway Administration.
The bridge, built in 1957, is structurally safe but is deteriorating, according to the State Highway Administration. The existing two-lane bridge will be replaced with a three-lane bridge. The third lane will carry westbound traffic.
The bridge will remain open to traffic because construction will be done in stages, with a shift in the roadway alignment to the north and the construction of an additional westbound lane along Middletown Road. There will be some traffic impact when the contractor ties the new roadway into the existing alignment.
The nearby Park & Ride lot will lose 20 of its 60 spaces so construction equipment can be parked there. Although the lot will remain open, commuters are encouraged to use Park & Ride lots at Exit 36, Old York Road, and Exit 27, Mt. Carmel Road.
The finished bridge roadway will be 43-feet wide and will look similar to the Freeland Road bridge, which was completed in 2007.The project is estimated to cost $5.4 million and will take almost two years to complete.
