Loop 303, Lake Pleasant Parkway to I-17 Improvements
Loop 303, Lake Pleasant Parkway to I-17 Improvements
Contents
Overview
The Arizona Department of Transportation, in association with the Maricopa Association of Governments, and in coordination with the Federal Highway Administration and the cities of Phoenix and Peoria, has initiated a study to consider an additional general-purpose lane on Loop 303 between Lake Pleasant Parkway and Interstate 17, as well as possible future traffic interchanges on Loop 303 at 67th, 51st and 43rd avenues. The study will also determine the approximate timing of the implementation of the I-17/Loop 303 system interchange ramps. The project seeks to address growing traffic demands on Loop 303.
Project Elements
This project will provide an update to the 2006 Final Design Concept Report Estrella Freeway (Loop 303), Happy Valley Road to I-17. Currently the segment of Loop 303 from Lake Pleasant Parkway to I-17 provides two lanes in each direction of travel. The project will consider the addition of a third general-purpose lane in each direction of travel, as well as develop and evaluate service interchange alternatives at 67th, 51st and 43rd avenues, and the implementation timing of the direct connecting ramps at the I-17/Loop 303 system interchange.
Schedule
- The project is currently in the study phase for the general-purpose lane widening. Construction of the 51st Avenue and 43rd Avenue traffic interchanges began in September 2022 and is anticipated to finish in late 2023.
- Timing of the construction of the remaining elements of the project is to be determined.
- Schedules are subject to change.

Project Overview
In September 2022, the Arizona Department of Transportation, in coordination with the Maricopa Association of Governments, the Federal Highway Administration and the city of Phoenix, began construction on new Loop 303 traffic interchanges at 51st and 43rd avenues. The new interchanges will address expected traffic growth prompted by current and planned development in the area. The project is expected to be completed in the fall of 2023.
In addition to the new traffic interchanges, the project also will include:
- Constructing new bridges on Loop 303 over 51st and 43rd avenues
- Extending 51st and 43rd avenues through ADOT right-of-way to the south of Loop 303
- Extending the southbound frontage road from 43rd to 51st avenues
- Drainage improvements at 51st and 43rd avenues
- Signals at ramp and crossroad intersections
- New signs, pavement markings and lighting
The 51st Avenue interchange will be shifted slightly to the west to accommodate the realignment of 51st Avenue.
What to expect
Construction will mostly occur outside the existing roadway. However, drivers can expect some weekend and night closures on Loop 303 during construction.
Note: While the city of Phoenix’s long-range transportation plan identifies the planned extension of 43rd, 51st and 67th Avenue/Pyramid Peak Parkway south of Loop 303 based on future development, the city has no immediate plans to extend any of these roadways.
