RI-4 and US-1 through South County

Routes 4 and 1 (RI-4 / US-1) provide a high-speed route between I-95 in West Warwick and the Westerly Bypass (RI-78). This routing is a separated, 4-lane highway for the entire route, with some portions using grade-separated interchanges and other portions using at-grade intersections. The question of whether portions of this routing should be tagged with highway=motorway or highway=trunk was discussed with the community[1][2]. The consensus is that multiple consecutive grade-separated interchanges are required in order to qualify as a highway=motorway. Based on these discussions, these roads are to be tagged as follows:

  • RI-4 is tagged highway=motorway between I-95 and its intersection with Oak Hill Road in North Kingstown.
  • US-1 is tagged highway=motorway for an approximately 2-mile section east and south of the village of Wakefield where the highway passes through a series of consecutive grade-separated interchanges.
  • The remainder of RI-4 and US-1 are tagged highway=trunk, including the section of US-1 that passes through a cloverleaf intersection with RI-138.
  • The entire route from the I-95/RI-4 intersection in West Warwick to the Westerly Bypass is tagged with expressway=yes.
