SR-74 Carefree Hwy - New traffic interchange TRAC # H706001
RTP Phase 1 Project Description The project removed and then reconstructed a new traffic interchange at Interstate 17 and State Route 74 (Carefree Highway). The new traffic interchange is a full-diamond interchange with the addition of two loop ramps. Also included were auxiliary lanes on I-17, lighting upgrades, improved drainage and rubberized asphalt.
Project Benefits The loop ramps allow for seamless merging for the heavily traveled directions of northbound I-17 to westbound SR 74 and westbound SR 74 to southbound I-17. Because it was paved with rubberized asphalt, traffic noise was reduced and drivers have a smoother ride.
