Loop 303

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.

On September 8, 2023, ADOT opened new interchanges at 43rd and 51st Avenues to provide access for the future TSMC factory in North Phoenix and as part of the ongoing Lake Pleasant Pkwy to I-17 improvement project. The project will also include an interchange at 67th Avenue and new ramps at Interstate 17 some time in the future.

SR 517

Originally, Loop 303 was proposed as State Route 517. Overall, the current route of the freeway is kind of similar to how it actually turned out; however, the original proposal protrudes out more northwest than the existing path of Loop 303 today. Also, since the extension of Loop 303 south of I-10 down to MC 85 will be starting soon, it will finally complete this original SR 517 proposal.
