Soon after the bypass and business routes merge, US 6 enters Johnston. Several miles later it intersects with Interstate 295. From I-295 to Olneyville, the old road — Hartford Avenue — is now U.S. Route 6A, as US 6 uses the Dennis J. Roberts Expressway. To get there, it turns south on the I-295 collector/distributor roads to the west end of that freeway.
