The County Materials Complex is a public-private partnership to construct a major event facility, a 24-hour fitness/wellness center, fieldhouse and a Mayo Clinic Health System sports medicine clinical location. First envisioned in 2014, construction on the complex is beginning in the spring of 2022 and will replace UW-Eau Claire’s Zorn Arena to become the largest indoor event venue in northwestern Wisconsin.
