SR Loop 202 at I-10 - Phoenix, AZ
Arizona Loop 202 west at the systems interchange with Interstate 10 along the Chandler and Phoenix city line. 04/28/12

Arizona is one of two lower-48 states without a three-digit Interstate route. The Phoenix area loops (101, 202 and 303) would make logical three-digit loops for I-10 or I-17, but were built with state funds and therefore not eligible as Interstate Highways.

I-16 west at I-95 - Pooler, GA
Interstate 16 west at I-95 near Pooler, Georgia. 01/03/14

Rural cloverleaf interchanges were once more prevalent at Interstate junctions. Weaving traffic patterns and increasing traffic counts resulted in upgrades of many throughout the system. Construction replacing the cloverleaf at I-16/95 started in March 2020.
