Columbus Mid-West Campus Tunnel Project

Ohio State University Facilities Operations and Development (FOD) and ENGIE will be removing or partially removing several tunnel sections from the mid-west campus in summer 2024. The area near the Chadwick Arboretum surrounded by Plumb Hall, Kottman Hall, Howlett Hall, the Parker Food Science and Technology Building, and the Animal Sciences Building will mainly be affected by work. Steam outages, natural gas outages, lot closures, and road closures will be required throughout the summer to remove or relocate utilities that affect facilities as well as work to remove the tunnel infrastructure. 

Below is a list of work that will directly affect operations, events, and parking:  

Plumb Hall Parking Lot Partial Closure – Starting April 30, the south half of the Plumb Hall parking lot will be closed to all traffic. Dumpsters will be relocated to the northeast side of Plumb Hall for the summer. 

Plumb Hall Parking Lot Full Closure – Starting May 6, the day after graduation, the entire Plumb Hall parking lot will be closed, except for several ADA spots and the northwest ADA entrance, through the remainder of the summer. 

Agricultural Engineering Building Steam Outage - Starting May 6 through the afternoon of May 8, a steam outage is required and will affect the Agricultural Engineering Building as well as the French Field House, St. John Arena, and the ice rink.

Additional communications will be sent throughout the summer to address other impacts to operations, events, and parking as dates are scheduled for work that affects the CFAES community. For more information, visit
