Study History

The initial Phase I study, completed in late 1998, focused solely on a possible bypass around Wickenburg. That study identified and evaluated 34 possible bypass corridors suggested by both ADOT and the public. Each suggestion was evaluated based on socioeconomic and environmental impacts as well as technical feasibility. Most of the suggested bypass locations were eliminated from further consideration  because of  impacts  to residential areas, parks, the Hassayampa River, wildlife habitat, historic sites, or due to challenges associated with very rugged terrain. Two corridors met the general selection criteria for the bypass that is, they would improve traffic operation while avoiding serious socioeconomic and environmental impacts.

The current Phase II study was initiated with information collection, including aerial photography, field reconnaissance, background data from involved agencies, and mapping. Public and agency scoping meetings were held in June 1999 to identify issues, concerns, and opportunities (ICOs) relative to the proposed bypass corridors and the improvements north of Wickenburg. Based on public opinion surveys and the input received at the scoping meetings, the Study Team established engineering and environmental evaluation criteria to be applied to the improvement alternatives. Then, the ICOs, study objectives, and evaluation criteria established through the agency/public scoping meetings were summarized in a Scoping Report.

Steering Committee meetings held throughout the study have provided a forum for input from county and local jurisdictional entities, ensuring that community concerns and local conditions are understood and incorporated into the study.

A public information meeting was held in Wickenburg in August 2000 to inform the public of the array of alternatives initially considered for the bypass corridor, the interim improvements, and the widening of US 93 north of Wickenburg, as well as which of those alternatives would be carried forward for further study. Public information meetings were held in Morristown in December 2000 and in April 2002  to address issues specific to that area, such as the impacts of the interchange of the bypass route and US 60 near the existing SR 74 intersection.

public information meeting was held in Wickenburg on December 5, 2001, to solicit input on the interim improvement alternatives and inform the public about the status of the bypass study.

The initial investigation involved identifying wide corridors in which a bypass could be located. Possible locations for roadway widening and the Wickenburg bypass routes were investigated and evaluated through an engineering and environmental overview. During the evaluation process, alternatives with fatal flaws were eliminated. After in-depth evaluation by the Study Team and public input from the  public information meetings, the viable alternatives for the bypass route were documented in the Initial Feasibility Report. The Final Feasibility Report was completed in July 2004.
