When Clark Construction and The MacKenzie Companies asked for a quick turnaround for 250 linear feet of pedestrian tunnel for the Michigan International Speedway, Advance Concrete answered by pouring multiple sections per day.  Each precast concrete ADSPAN® section was delivered in the upright position, allowing quicker unloading, installation, and reducing stress on the crane.  No tipping or turning is required when purchasing your 3-sided culverts from Advance.
