Interstate 410 was a proposed option in the 1960s for a freeway through Downtown Phoenix. This would eventually become I-10. A small section of I-410 was built from I-10/I-17 near Sky Harbor to Buckeye Rd. It was even signed on I-10 exit signage as seen from this image on AARoads. However, there was no signage for I-410 along the actual route. Previously, the north-south segment of the route was designated as I-510.
