The Arizona Department of Transportation, in coordination with the Maricopa Association of Governments and the cities of Phoenix and Peoria, is planning for improvements to Loop 303 between Lake Pleasant Parkway and Interstate 17 that will include an additional general purpose lane in each direction, bridges to accommodate a future interchange at 67th Avenue, and a new Loop 303/I-17 system-to-system interchange. The project seeks to address growing traffic demands on Loop 303.
