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.

Structures for the 366 Line have been completed in Millbury, Sutton and Northbridge. The installation of structures is now underway from Hazel Street to Taft Hill Road in Uxbridge. Over the next few weeks, work will continue to High Street and Richardson Street and from Quaker Highway to the point where the 366 Line crosses the Blackstone River.
Crews are installing access roads and work pads along the 366 Line right-of-way from the Route 146 on-ramp off Greenville Road to the West Farnum Substation. Foundation drilling is underway near East Harkness Road, Great Road, Victory Highway, Branch River Industrial Park, Pound Hill Road and Woonsocket Hill Road, and will continue to the area off Greenville Road to the West Farnum Substation.

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.
