Project: Big I Albuquerque
Summary
In the late 1990's, the "Big I" interchange in Albuquerque, New Mexico, which provides connections between Interstate 40 and Interstate 25, had become the 10th most congested interchange in the nation. Traffic volumes nearly ten times greater than capacity, combined with obsolete design features such as quick weaves, short on-ramps and left-hand exits, contributed to significant congestion and frequent crashes. Redesign of the interchange, ultimately reduced congestion delays by more than 90%.
