The goal of developers is to create a 50-mile network of trails along the historic Blackstone River's banks from Worcester, MA, to Providence, RI. Completed off-road sections in Massachusetts include a 3.5-mile segment from South Worcester to Millbury, and a 3.6-mile trail in Blackstone River and Canal Heritage State Park in Uxbridge. - Trail Map for the Park.
Currently, the longest off-road segment connects Woonsocket and Pawtucket in Rhode Island. Learn about the Blackstone River Greenway and Bikeway, with maps. Uses include biking, skating, fishing, horseback riding, walking and cross country skiing. The trail is wheelchair accessible.
