Relocating I-195 in Providence

RIDOT is in the middle of moving the interchange of I-95 and I-195 in Providence south to a location adjacent to the Providence Hurricane Barrier. Once the Iway projects are complete and all its roads, bridges and ramps are open, all ramps in the interchange will enter roadways from the right, in conformance with modern design standards.
