This project required the completion of Construction Data Forms for the Strategic Highway Research Program's (SHRP's) Specific Pavement Studies (SPS) Experiment Number 5, The Rehabilitation of Asphalt Concrete Pavements, and Experiment Number 6, The Rehabilitation of Jointed Portland Cement Concrete Pavements. In Arizona, the SPS-5 experiment construction was done in the eastbound travel lane of Interstate Highway 8, between mileposts 159 and 161 in southwestern Arizona. Eleven test sections were constructed for the experiment, with eight as set forth in SHRP guidelines. In addition, two additional sections were constructed, and one designated as the control section, for a grand total of eleven sections.

The proposed action is the construction and operation of a new multilane freeway in the metropolitan Phoenix area extending approximately 22 to 24 miles from Interstate 10 west of Phoenix to Interstate 10 southeast of Phoenix. The facility would be the final extension of State Route 202L, an element of the Maricopa Association of Governments' adopted Regional Freeway and Highway System.
