Bridge Deck Replacement

SPS reduces the deck dead load by up to 70%, allowing bridges to carry significantly greater live load without needing girder or pier strengthening. Load restrictions on bridges can be removed and extra lanes added to increase traffic capacity.

Deck replacement can be completed leaving the steel or concrete girders in place or, if speed is critical, by replacing the deck and girders with preassembled longitudinal deck-girder units. The replacement of these old decks takes days rather than weeks and bridges can often remain partially operational throughout the procedure.
