Dover Bridge Series 7

Fourteen months of highly orchestrated construction has resulted in a transformation that is hard to imagine without witnessing it firsthand. The Dover Bridge series continues with the seventh installment.
The substructure of twelve piers and two abutments are nearly complete with only the Caroline County side abutment left to be constructed. The embankments are now in their third 150-day quarantine period while incrementally layers of select borrow is added after each period. After another layer, the forth quarantine period will take place, then the final layer followed by an eight-month long quarantine period.
The superstructure consisting of:
• Twenty-five haunched steel girders over the river portion of the bridge weighing nearly three million pounds.
• Thirty-five prestressed concrete girders spanning the approach from the Caroline County side weighing three and a half million pounds.
• Thirty special sized steel girders weighing an additional one and a half million pounds.
totals nearly eight million pounds, or four thousand tons!
A compressed video documenting the placement of the last segment of girders from the Talbot County end abutment to the existing superstructure demonstrated the choreographed precision movements needed to position the girder in place with just 1/32 of an inch of tolerance. They make it look easy.
Enjoy.
