Arizona State Routes
Formed in 1927, Arizona's State Highway Commission was assigned the duty of adopting and designating state routes and US Highways. Arizona adopted 1,954 miles in the first year spread across 17 different routes, but there were many gaps in the highway system. Within a decade, the gaps had been filled, signs had been posted and maps made.
In the 1950's, Arizona's first freeway - the Black Canyon Freeway - was built and signed as part of SR 69. This was later certified as an Interstate and was given the number I-17, which replaced SR 69 not only along the Black Canyon Freeway, but as far north as the Cordes Junction. Arizona was able to get a jump start on the building of freeways, and had a sprawling network of Interstates, US Highways, and State Routes by the 1990's. Improvements and new building continue on, including the to-be-completed Red Mountain Freeway (SR 202L) and the planned SR 30 freeway.
