Objective: Reconstruct the most heavily traveled interchange in Minnesota while maintaining optimal traffic flow and minimal congestion over the course of two years.

Scope: 4.5 million lbs. of new structural steel for bridges, 4.2 million lbs. of rebar, 45,000 cubic yards of structural concrete and 37,000 cubic yards of pavement concrete.

Result: The 494/169 Design-Build was completed on time and on budget.
