The Rebuilding I-93 Salem to Manchester project involves the reconstruction of a 19.8-mile segment of I-93 in southern New Hampshire from the Massachusetts state line in Salem to the I-293 interchange in Manchester. Improvements include widening the highway, which currently features two general purpose lanes in each direction, to provide four travel lanes in each direction. The project also includes design modifications and infrastructure improvements including the replacement of red-lined bridges at five interchanges and the provision of three new park-and-ride lots, expanded commuter bus service to Boston, and enhanced Intelligent Transportation Systems (ITS).

Duration / Status

FHWA issued a Record of Decision (ROD) for the project in June 2005, but work on the project was delayed by a suit brought against the state and FHWA by the Conservation Law Foundation in February 2006. A supplemental EIS was prepared and ultimately received a Supplemental ROD in May 2010. During this period work that did not necessitate the widening of the highway was completed, including the repair/replacement of seven "red-listed" bridges and the construction of park-and-ride lots. As of March 2012 at total of 16 construction contracts with a total value of approximately $235 million had been awarded, 12 of which were complete. The entire project is expected to be complete by 2020.

Initial $80.0 million GARVEE bond transaction issued November 4, 2010. Second $98.25 million GARVEE issuance May 16, 2012.
