Boston Globe 7/17/13: Unlocking a secret network: Sections of old MWRA aqueducts are being transformed into 40 miles of public trails. Plans are moving forward to open public trails atop old aqueducts that snake through open space in 14 communities from Clinton to Boston. The section in Wellesley starting near the Waban Arches is expected to be officially opened by the town within weeks. A section is open in Framingham, and agreements are close in several other communities along the 40-mile system, according to MWRA officials. Since state officials first unveiled the plans just over a year ago, “no trespassing” signs that were posted along the out-of-service MWRA-owned aqueducts are coming down and slowly being replaced with new trail markers that authorize public, nonmotorized recreational use.
