The Blackstone River Valley

The Blackstone River Valley is a region of nearly 400,000 acres located within twenty-four communities in central Massachusetts and northern Rhode Island. Route 146 is the main highway running north and south between Providence and Worcester. It intersects with I-95 and I-295 in Rhode Island and I-90 (Massachusetts Turnpike) in Massachusetts.

Directional signage along these major highways points the way to our six Visitor Centers. Visitor Centers are located in Providence, Pawtucket, Lincoln and Woonsocket, RI as well as Uxbridge and Worcester, MA.

Please also look for signage directing you to tune to AM 1140 for further directions and visitor information while traveling along major highways in the Blackstone River Valley.
