This project includes the complete rebuilding of the superstructures, substructures and approaches for the Centerville Road Bridge and the Toll Gate Bridges which carry I-95 over those respective roads. Although not structurally deficient, both of these bridges are in fair condition which is one step from structural deficiency.
The bridges carry 178,000 vehicles daily. They were built in 1951. In a unique construction sequence, RIDOT first built a temporary road in the I-95 median between the two bridges. At the time of the bridge replacement, both north and southbound traffic will shift on to this road for a period of eight days.
During the eight day construction period, workers will employ the Self Propelled Modular Transport (SPMT) method of bridge replacement which puts the bridge into place in a smaller window of time. This was the method used on the East Shore Expressway.
