Former deputy director for the Arizona Department of Transportation brings more than three decades of transportation experience to his new leadership role at the firm.

TEMPE, ARIZONA— Dallas Hammit is joining the Southwest Mountain District leadership team at WSP USA, a leading engineering and professional services consultancy.

Hammit will support the district across all business lines by providing marketing, sales and technical leadership; by maintaining relationships with top clients in the district; and by leading national business line strategy and enhancing our collaboration and client focus. He will be based in Tempe.

Hammit brings more than 30 years of transportation industry experience to WSP, most recently serving as the Arizona state transportation manager for a southwestern U.S.-based engineering firm. He previously worked for the Arizona Department of Transportation (ADOT), where he served in a number of leadership roles, including seven years as deputy director of transportation and state engineer. Earlier in his career he worked as a district engineer for the Prescott and Yuma districts in Arizona, a senior resident/maintenance engineer for the Yuma district, and as a resident engineer for a Wichita, Kansas-based engineering firm.

“Dallas brings a high level of expertise to the Southwest region, where WSP continues to experience tremendous growth,” said Shaun Grimm, senior vice president and Southwest Mountain District lead. “His 22 years at ADOT has provided him with an in-depth, client’s perspective on the key issues and challenges facing decision makers in the transportation market, which will help us develop a more complete understanding of how WSP can partner to achieve their objectives.”

Hammit is a graduate of the University of Wyoming with a bachelor’s degree in mechanical engineering and Casper College with an associate degree in engineering. He was chair of the American Association of State Highway and Transportation Officials (AASHTO) construction committee, vice chair of the AASHTO Innovation Initiative, and chair of the Western Association of State Highway and Transportation Officials (WASHTO) construction and materials committee.

“His background and experience, as well as his passion for supporting the infrastructure needs of our Southwest Mountain states, including Arizona, Colorado, New Mexico, Utah and Wyoming, make him a valued addition to our team,” Grimm said.
