Project Overview
Tunneling Activity
Tunneling operations are now complete with the tunnel boring machine (TBM) being disassembled and removed from the tunnel in Pawtucket. The next phases of the project include the construction of various surface access points (drop shafts) and connections to the tunnel (adits). This work is already underway in some locations and is will be completed over the next couple of years.
Important Information about Controlled Blasting Activities
Controlled Blasting Activities have started taking place at 660 Roosevelt Avenue and 50 Pleasant Street in Pawtucket. We anticipate not more than three (3) blasts per week per site (likely alternating days between sites). Blasting at both sites will be below surface and CB3A anticipates minor disruption to the adjacent neighbors, similar to the sound of a large truck passing by or a rumble of thunder.
A series of HORN signals will be used to warn personnel at the site and nearby residents prior to each blast. Each blast will be preceded by a security check of the affected area and then a series of warning pulses.
To sign up for blasting notifications (sent approximately 24 hours prior to planned blasting activity), please send an email to notifications@cb3a.com requesting to be added to the list.

In an effort to continue its compliance with the federal Clean Water Act, and with the intention of returning some of Rhode Island’s most vulnerable waterways back to their natural conditions, the Narragansett Bay Commission recently launched Phase III of its RestoredWaters RI project. The first two phases, completed in 2008 and 2014, respectively, have significantly improved the health of upper Narragansett Bay along with a number of its tributaries. When the centerpiece of Phase III – the Pawtucket Tunnel – is complete, storm-related sewage discharges from the area will have decreased by 93 percent.
With an anticipated completion date of 2027, the Tunnel will travel through Pawtucket, Central Falls and East Providence at a depth of approximately 125 feet below the ground. At 2.2 miles long and 30 feet in diameter, it will have a storage capacity of more than 58 million gallons of stormwater. In addition to the Tunnel, Phase III includes the installation of four drop shafts, a launch shaft and a receiving shaft.
