Joe Heller, our resident engineer on a big project getting underway in the North Valley, joins On the Road With ADOT this week to explain what's coming over the next two and a half years, including a flyover ramp connecting northbound I-17 with Loop 303.
A major component of the work will be building the direct ramps to create the freeway-to-freeway interchange. When completed over the next two-and-a-half years, drivers will skip the traffic signals at the current Loop 303/I-17 diamond interchange.
