In March 2014, the reconstructed Prince Road traffic interchange opened to traffic after being closed at the start of the project in fall 2011.
The new overpass, which was built 30 feet above ground level on the east side of I-10 and which slopes down to reach current ground level, is a key part of a $76.4 million I-10 widening project between Ruthrauff and Prince roads. The project upgrades a two-plus mile section of I-10 by increasing capacity, reducing congestion and improving traffic flow on this highly traveled corridor in Tucson.
The previous at-grade interchange experienced significant congestion and backups when trains passed through this area, sometimes causing a line of vehicles to form on the I-10 exit ramps during peak hours.
While the new Prince Road interchange is now open, there is additional work on the I-10 / Ruthrauff Road to Prince Road widening project that needs to be completed, including at the Prince Road interchange. The eastbound I-10 entrance ramp at Prince Road will remain closed for another month so that crews can complete landscaping, electrical and barrier installation. The eastbound I-10 exit ramp is currently open and will remain open.
In addition, currently traffic is traveling on the three inside lanes of I-10 and will remain in this configuration through May when ADOT will repave the entire project when temperatures are ideal for this work. Once final paving is completed, I-10 will be expanded to four lanes in each direction.
