The Interstate Reliability Project is a proposed 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 proposed 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.

Tree clearing which started at the Millbury 3 Switching Station has continued all the way down the right-of-way along Stone School Road, past the intersection of Armsby Road. Current activity is in the area of Central Turnpike and Smith Road.
Tree crews will continue along the right-of-way over the next few weeks moving in the following direction:
Over the next few weeks installation of matting, work pads, and road construction in the right-of-way will continue from Millbury 3 Switching Station, all along the transmission corridor heading towards Route 146 and continuing to the Northbridge town line.
In the past few weeks tree clearing crews have moved past the intersection of Pound Hill Road and Old Oxford Road to the previously cleared point off Bearskin Farm Road in North Smithfield. Tree crews have now been relocated to the Providence Pike (Route 5) area and are currently working east to Woonsocket Hill Road.
Foundation drilling activity continues at various locations along the right-of-way. Multiple foundation drilling crews are now working the corridor from Joslin Road, Burrillville, to Black Plain Road, North Smithfield, continuing to make preparations for the new transmission line structures.
Installation of matting, work pads, and road construction in the right-of-way will occur at intervals all along the transmission corridor from Sherman Farm Road in Burrillville to the West Farnum Substation on Greenville Road in North Smithfield.

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.
