Named New Hampshire DOT commissioner in December 2022, Cass originally joined the agency in 1986. He held a number of supervisory and management positions during his tenure with New Hampshire DOT, including final design supervisor, preliminary design section head, chief project manager, assistant director of project development, and director of project development.
He was also one of the project managers for the largest project ever undertaken by the New Hampshire DOT – the 20-mile, $800 million reconstruction and widening of I-93 from Salem to Manchester.
Cass oversaw other key state transportation projects as well, including major Portsmouth bridge projects involving the Sarah Mildred Long Bridge and the Memorial Bridge.
Those efforts improved safety, strengthened regional connections, and supported the long-term reliability of the state’s transportation system, noted Governor Kelly Ayotte (R) in a statement.
“I’m grateful to Commissioner Cass for his many years of dedicated service to New Hampshire,” the governor added. “Thanks to his leadership and the hardworking team at NHDOT, we have some of the best roads in the country. We will miss him, but we wish him all the best in his retirement.”
“I take great pride in being part of NHDOT and in working alongside some of the most dedicated public servants you will find anywhere,” Cass said. “Our progress on critical infrastructure, safety, and system operations is a direct result of their hard work, integrity, and commitment to the people of New Hampshire.”
