Work has begun to prepare the area around Interstate 95 at Exit 17 for a major bridge replacement project and other improvements. One phase will build temporary supports for two work areas on Saugatuck Avenue on each side of I-95. That’s where two new spans will be built. Later, the northbound and southbound spans will be demolished, and with the use of heavy hydraulic jacks, new spans will slide into place over Saugatuck Avenue. The span replacements will be done “utilizing an Accelerated Bridge Construction Method called Lateral Slide, which minimizes the disruption to I-95 commuters,” the DOT has said.
