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 activity during the past week has been active from the Rhode Island state line moving north towards Quaker Street in Millville. Over the next few weeks the tree crews are scheduled to finish the remaining work in Millville and Uxbridge along the right-of-way. This will substantially complete the tree work in Massachusetts, except for certain areas where environmental restrictions and access limit the work.
The installation of matting and work pads, and road construction in the right-of-way have been underway from the Millbury #3 Switching Station heading towards the Rhode Island state line. The removal of the vacant lattice structures has been going smoothly, with more than 65 of the 114 towers (57%) now completed.
The drilling stage of construction has started in the area of the Millbury #3 Substation. Foundation work will continue along this route south towards Boston Road in Sutton.
Tree clearing crews working on the Massachusetts portion of the Interstate Reliability Project have now moved across the Rhode Island state line at Central Street moving towards Pratt Pond in North Smithfield. Tree clearing work will now be active in both North Smithfield and Burrillville.
The new structures are being set into place. Some 38 structures (27%) have been erected for the new 341 line. This new line will run almost 18 miles from the West Farnum Substation in North Smithfield, through Burrillville to the Connecticut border.

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.
