Loop 303
State Route 303 is the third of the 3 highways that "loop" around the Phoenix area. The Loop 303 is the only loop that is currently signed as north/south for its entire length. Loop 303 is the newest loop, and because of that, it's also the shortest. There are two upcoming construction projects on Loop 303. In Fall 2022, construction is expected to start on an additional lane between Lake Pleasant Pkwy and I-17 and new interchanges for 67th, 51st, 43rd Avenues, and I-17. In 2024, construction is expected to start on a new extension of Loop 303 from Van Buren St, south of I-10 to Elwood St.
Cool Features
The Loop 303 is fully designated as the Bob Stump Memorial Parkway.
All of the loop highways were originally signed with uniquely colored route shields; the 303's being an inverted standard shield. However, due to the Loop 202's brown shield being very vulnerable to fading, and that it was seemingly hard for contractors to get the colored signage correct in general, the colored shields were phased out. It is unlikely that there are many old Loop 303 shields still out in the wild since it was upgraded to a proper freeway.
