Route 331 Dover Bridge Replacement over the Choptank River
McLean Contracting Company has been awarded a $47,978,312.29 contract from MdSHA to replace an existing two-lane swing span bridge (Dover Bridge) with a 2,021-foot long, 44-foot wide, 50-foot high fixed span bridge along MD 331 over the Choptank River between Talbot and Caroline Counties, Maryland. The proposed project will replace the existing Dover Bridge with a fixed span bridge directly downstream of the existing bridge, allowing the historic Dover Bridge to remain in place and operational during construction.
The new bridge will feature concrete granite lined river foundations supported by 48-inch steel pipe piles. The substructure will have hammerhead caps and columns with architectural concrete that features marshland and wildlife accents. The superstructure consists of haunched structural steel girders over the river and adjacent spans. The approach spans over the marshland are founded on 36-inch steel pipe piles with concrete caps and prestressed concrete girders. When completed the existing swingspan will be renovated and left in place after construction of the new bridge for historical purposes.
