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.

The wire work from the Millbury #3 Substation to Route 146 in Sutton has been completed. Wire pulling will continue from Route 146 towards Mendon Road, pass through a small area of Northbridge at Main Street and proceed south along the transmission corridor to Lackey Dam Road.
The drilling and foundation work from Sherman Farm Road west to the Connecticut state line has been completed. The last 14 structures, located from the Munyan Trail to the Connecticut state line, will be erected before the end of April.
Crews are installing access roads and work pads along the 366 Line right-of-way. Over the next few weeks, foundation drill crews will be working along the transmission corridor near East Harkness Road, Victory Highway, Branch River Industrial Park, Pound Hill Road, Woonsocket Hill Road and Greenville Road.

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.
