Additional Info
Arizona Loop 202 west at the symmetrical stack interchange with Interstate 10 along the Chandler and Phoenix city line. Photo taken 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 thus not Interstates.
Interstate 16 west at Interstate 95 near Pooler, Georgia. Photo taken 01/03/14.
Rural cloverleaf interchanges were once more prevalent at Interstate to Interstate junctions. Weaving traffic patterns and increasing traffic counts have led to upgrades of many throughout the system. The exchange between I-16 and I-95 is one that remains in its original configuration.
