The Interstate Reliability Project is a 345-kilovolt (kV) transmission project in an existing transmission right-of-way. It is one of four New England East-West Solution (NEEWS) 345-kV transmission projects serving portions of New England. The Interstate Reliability Project is needed to meet the demand for electricity and support the reliable delivery of electricity to customers under many different conditions.
The Project begins in Millbury, Massachusetts and continues along the existing transmission line rights-of-way (ROW) into North Smithfield, Rhode Island. It continues west to Burrillville, Rhode Island and into Connecticut where it will connect to a new line being constructed by Connecticut public utility, Northeast Utilities.

Crews are delivering materials for wire installation to sites along the 366 Line transmission corridor from Uxbridge south to the Rhode Island state line.
More than half of the wire work for the Massachusetts portion of the 366 Line has been completed. Wire work is underway from River Road near the Blackstone River in Uxbridge, to Quaker Street and Providence Street in Millville to the Rhode Island state line.
Construction of the new Sherman Farm Road Switching Station is 80% complete. Installation of wire, perimeter fencing and lighting are underway. Equipment, including the existing control house, will be dismantled and removed after the new switching station becomes operational.
* The installation of new 328 Line structures from the West Farmum Substation in North Smithfield to Sherman Farm Road is 50% complete.*

The Interstate Reliability Project encompasses approximately 15.4 miles of ROW in Massachusetts through the towns of Millbury (.7 mile), Sutton (6.2 miles), Northbridge (.3 mile), Uxbridge (7.6 miles), and Millville (.6 mile); and 22.5 miles in Rhode Island through the towns of North Smithfield (9.3 miles) and Burrillville (13.2 miles).
National Grid reminds off-road drivers that utility rights-of-way are private property where unauthorized dumping and trespass by motorized vehicles is unlawful. These rights-of-way are a critical part of the company's electric and gas network. Limiting activities within the corridors protects the public, avoids damage to company facilities and supports the reliability of electric and gas service. For more information, click here.
