The MnDOT District 8 Headquarters serves a large area covering ten percent of the state’s land across southwestern Minnesota. The existing Headquarters facility is located on a site adjacent to the highway system on the east side of Willmar. The existing facility is now undergoing a major renovation and expansion to prepare for the future and better serve the District population. The site offers space for expansion in many directions. An expansion to the north side of the building was chosen to minimize the impact to the existing site circulation and truck door access. This location also provides a large shared wall with the existing building. The expansion of 28,000+ square feet includes a 22,200-square-foot heated truck storage area; 1,200-squarefoot wash bay; and 5,000 square feet for the radio shop, building maintenance, and office area. Much of the existing heated truck garage area will be renovated, with some storage areas converted to office space. In addition, ADA updates will be made to the existing office area. Relocated departments will make room in the existing facility for conversion to house the fleet and sign shop, vehicles, and sign storage. A new training room to accommodate 100 people will provide space for MNDOT staff to hold internal educational, organizational, and emergency mobilization meetings.
