Travel directions

Immediately north of downtown, SR-146 branches off Interstate 95, which runs to Boston. The highway is then called the Louisquisset Pike and has 2×2 lanes. It passes through the northern neighborhoods of Providence and then through wooded areas. One then crosses Interstate 295, the city’s bypass, after which the highway is briefly interrupted by a 2×2 main road with at -grade intersections. The highway resumes at Woonsocket and continues to the Massachusetts border .

Exact opening dates of the SR-146 are unknown. Most of it had opened in the 1960s or 1970s, although there were a number of intersections in the less densely populated north of Providence for quite some time, at least until the late 1980s. Today, there is only one traffic light in North Smithfield.

Exit numbering according to distance was introduced in May 2019 . Before that, State Route 146 had no exit numbers.

On June 3, 2022, a $196 million project to reconstruct State Route 146 just off I-295 into a full-fledged freeway began. At the intersection with Sayles Hill Road, the only traffic lights on the route have been replaced by a connection, frontage roads have also been constructed and the connection with State Route 146A at Woonsocket has been made safer by replacing a U-turn with a diverging diamond interchange. Also, the entire road between I-295 and the Massachusetts border has been resurfaced.

Traffic intensities

The highway is busiest off I-95 with 63,000 vehicles per day, which descends slowly north.
