Route 4, also known as the Colonel Rodman Highway, is a 10.37-mile-long (16.69 km) numbered state highway located in Washington County and southern Kent County, Rhode Island, United States. The route is a major north–south freeway in the southern Providence metropolitan area, directly linking Providence with eastern Washington County, the beaches of Narragansett and South Kingstown, and the city of Newport. Route 4 begins as a two-lane divided highway at an intersection with U.S. Route 1 (US 1) in the town of North Kingstown, becoming a limited-access freeway after 1.89 miles (3.04 km). The route has four numbered interchanges before terminating in the city of Warwick, where the northbound lanes merge into Interstate 95 (I-95).

The origins of Route 4 date back to 1952, when construction began on a short, unnumbered arterial from US 1 to the modern location of exit 3 at Routes 2 and 102 in Wickford. In 1965, the Rhode Island Department of Public Works began work on a 5.4-mile (8.7 km) freeway from modern exit 5 north to the merge with I-95. The freeway, designated as Route 4, was completed in 1972. At that time, the Route 4 designation was also applied to the Wickford arterial. In 1988, the missing link in Route 4 between exits 3 and 5 was completed and opened. The Rhode Island Department of Transportation had long-term plans to upgrade the southernmost portion of Route 4 to freeway status by constructing overpasses at Oak Hill Road and West Allenton Road and a grade separation with US 1. Although the project was originally scheduled to be completed by 2007, the $55 million project has been postponed indefinitely.
