The I-40/Coors Interchange Reconstruction Design-Build project is one of the most complex, high-profile design-build projects undertaken in New Mexico to date. More than 100,000 vehicles including numerous heavy trucks pass through the interchange in a single day. Coors Boulevard is the only north-south principal arterial on the west side that serves both local traffic and regional transportation needs. The Interchange, built in the 60s, was handling more than twice the number of automobiles it was designed for. As part of the design-build team, Terracon was selected to provide geotechnical engineering design services.
