Reminder to travelers: the second landslide of the Pontiac Avenue bridge will take place this weekend

RHODE ISLAND, Nov. 16 – The Rhode Island Department of Transportation (RIDOT) reminds motorists that the second bridge slide of the weekend for the Pontiac Avenue Bridge in Cranston is scheduled to begin Friday evening, Nov. 18. All roads are expected to reopen at 6 a.m. Monday, November 21.

The bridge slide necessitates a closure of Pontiac Avenue at the Route 37 overpass. Parts of Route 37 East will be affected, but travelers will access the Pontiac Avenue ramps to easily navigate Route 37. RIDOT expects travel delays and strongly encourages travelers to consider alternate routes to access the bustling Reservoir Avenue shopping district, including the Garden City and Chapel View malls.

RIDOT constructed the new bridge decks along Pontiac Avenue adjacent to Route 37. Like last weekend, RIDOT will demolish half of the bridge and slide the new bridge deck into place using transporters multi-wheeled self-propelled modulars.

The Department recommends that drivers consider alternate routes such as Route 10 to Route 2, I-295 to Route 2, and I-295 to Route 37 to reach their destinations. Reported deviations include:

Route 37 East: Use Exit 1E (Pontiac Avenue) as a detour and return to the highway using the nearby Route 37 East ramp. Police will be present to ensure the flow of traffic in the detour.

Pontiac Avenue Southbound: Use Sockanosset Cross Road westbound to Route 2 South to the on-ramp to Route 37 East.

Pontiac Avenue Northbound: Use the ramp to Route 37 East and use Exit 2B for I-95 North, returning to Route 37 West (Exit 31B) and taking the exit ramp at Exit 1E to Pontiac Ave.

Bridge slips are a form of accelerated bridge construction that saves an additional 24 months over conventional construction methods. This rapid approach minimizes overall disruption to traffic and surrounding commercial areas, limiting noise and vehicular emissions associated with much longer duration construction projects.

This $75.9 million multi-bridge project repairs deficient bridges along the Highway 37 corridor with the preservation, major rehabilitation and/or reconstruction of 15 bridge structures in Cranston and Warwick. Six of these bridges are structurally deficient. Four bridges will be replaced and two other bridges will be rehabilitated. The project also includes safety improvements at the Pontiac Avenue interchange from Route 37 West.

Route 37 is a critical east-west highway in central Rhode Island, connecting the towns of Cranston and Warwick, major commercial, office, and residential areas, Interstate highways, and Rhode Island TF Green International Airport. With daily traffic of 42,000 vehicles, Route 37 is one of the busiest corridors in the state.

The project is funded in part by a $20 million federal TIGER grant secured by the Rhode Island Congressional Delegation. It will be completed in the spring of 2023.

All construction projects are subject to schedule and scope changes based on needs, circumstances, discoveries and weather conditions.

The Route 37 project is made possible by RhodeWorks and the Bipartisan Infrastructure and Improvement Act. RIDOT is committed to restoring Rhode Island’s infrastructure to good condition while respecting the environment and striving to improve it. Learn more about
