GM2 is serving as the owner’s representative for this Design-Build project encompassing the I-691EB to I-91NB Interchange improvements. Project 0079-0245 addresses operational and safety concerns associated with capacity, congestion and weaving at the I-691 eastbound to I-91 northbound interchange. The project entails approximately 2.1-miles of highway, including pavement rehabilitation, roadway safety improvements, repair/rehabilitation of 4 bridges, rehabilitation and widening of one, and replacement of one. Illumination will be upgraded, drainage improved, and signage replaced. As the owner’s representative, GM2 is developing 30% design documents, specifications, and design-build proposal documents, as well as all preliminary permitting. 

This project has been selected, at GM2’s recommendation, for implementation under current budgetary constraints, but it is actually one part of a larger, $300M project for major interchange improvements at this location.
