Rhode Island Route 403

Rhode Island Route 403

Route 403, also known as the Quonset Freeway, is a numbered state highway located in Washington County and Kent County, Rhode Island, United States. The route is a nominally east–west limited-access freeway for its entire length. A spur of Rhode Island Route 4, Route 403 serves Davisville and the Quonset Business Park, providing freeway access to Interstate 95 and the northern Providence metropolitan area from the industrial zone. The western terminus of the freeway is at a trumpet interchange with Route 4 in East Greenwich. The route has three unnumbered interchanges along its 4.5-mile (7.2 km) length, including a junction with U.S. Route 1 in North Kingstown, before terminating at an at-grade intersection with Roger Williams Way and Commerce Park Road in Quonset. Route 403 is the highest numbered route in Rhode Island.

Prior to 2006, Route 403 was a narrow, two-lane road through Davisville. The western terminus of the route was at an interchange with Route 4 and Rhode Island Route 402 in East Greenwich, and the eastern terminus was at U.S. Route 1 in North Kingstown. In order to accommodate increasingly heavy commercial and commuter traffic to and from the Quonset Business Park, the Rhode Island Department of Transportation constructed the Quonset Freeway as an upgraded Route 403. The relocation of the route began in 2000 and was constructed in two phases; Phase 1, a freeway from Quonset to Davisville, opened in June 2006. Phase 2 of the relocation project, which connected the freeway with Route 4, was completed one year ahead of schedule in December 2008.
