Interstate 17/Interstate 40 Traffic Interchange Project
The I-17/I-40 TI project involved rebuilding the interchange where two high volume interstates meet in Flagstaff, Arizona. The Vastco team delivered a traffic interchange with a half-mile post-tension concrete signature flyover bridge, 5 additional bridges, and 1 tunnel. This high-profile TI was delivered to ADOT 19 months ahead of schedule and included $1.5 million in Value Engineering savings. This project was awarded the prestigious Marvin M. Black Award for Excellence in Partnering in 2003.
