The second round of studies includes I-8 from California border to I-10, I-40 from I-17 to New Mexico, SR 95 from I-8 to I-40. The third round of studies included I-10 East (SR 202 to New Mexico border), I-10/SR 85 (California State line to Junction I-8), SR 87/SR 260/ SR 377 (Junction SR 202L to Junction I-40), US 60/ US 70/ US 191 (US 60/US 70 (SR 79 to US 191) and US 191 entire length) and US 93/ US 60 (Nevada State line to SR 303L. Fourth round of Corridor Profile Studies are underway. Statewide map shows all the corridors that are being studied. The studies under this program will provide a strategic vision for assessing the overall health of the state's primary highways, assisting the agency with transitioning to a performance-based project programming system through targeted investments.
