The Hopkinton Trails Committee and the Hopkinton Trails Club have created a monthly trail volunteer day on the first Saturday of each month from 9 a.m.-noon. The next workday is Saturday, Aug. 2. This is the second of three planned bridge projects in the Berry Acres property. It will reopen access to a trail that’s been unused for several years. Participants can park at the West Main Marketplace (by The Spoonery, off Independence Place, opposite Freedom Way). For more information, visit hopkintontrailsclub.com.
