The I-10 Broadway Curve Improvement Project just finished phase two and is entering its third.

During the last phase, crews removed and replaced the 48th Street and Broadway Road bridges. They also constructed new walls and began building Collector-Distributor (CD) roads, which are meant to separate through-traffic from entering and exiting vehicles.

ADOT estimates the third phase to last through late summer 2024.

From now until then, crews will widen roads and bridges, and rebuild ramps on 32nd Street. Other work includes drainage and bridgework and finishing the CD roads.
