Construction of the section of Loop 101 known as the Agua Fria Freeway first began in 1985, after Maricopa County voters approved Proposition 300, which established a 20 year half-cent sales tax to construct Valley freeways.
Today, Loop 101 (Agua Fria Freeway) is a six lane highway extending north from Interstate 10 (I-10) and west to Interstate 17 (I-17). Loop 101 is an integral part of the Valley freeway system and serves as the link between these two Interstate highways that are important routes for transportation and commerce.
