Rhode Island Route 99 - Route Description

Route Description

Route 99 begins at a partial interchange with Route 146 in Lincoln; the route is only accessible from Route 146 north, and the mainline of Route 99 south defaults onto Route 146 south with no direct access to Route 146 north. The exit for Route 99 off Route 146 north is accessed via a collector road that also serves Interstate 295 from Route 146; I-295 has an alignment slightly south of Route 99 but has no direct interchange with it.

Route 99 north diverges from Route 146 north and heads in an almost due north direction. The freeway has its only interchange with Sayles Hill Road, an unnumbered road that is used to access the village of Manville and Route 126 (Old River Road). Sayles Hill Road is also used to access Route 146 north, which has no direct freeway connection with Route 99 south.

After the Sayles Hill Road interchange, Route 99 begins to head in a northeastern direction, passing to the west of the densely populated village of Manville and the St. James Cemetery. Route 99 passes over Route 126 (Old River Road), Railroad Street, and the Providence and Worcester Railroad on a single-span bridge before crossing over the Blackstone River into the town of Cumberland. The freeway passes over 2nd Avenue before entering the city of Woonsocket shortly before its northern terminus at a traffic signal with Route 122 (Mendon Road). The road continues northward as Highland Corporate Drive, an unnumbered route that enters the Highland Industrial Park.
