The Marquette Interchange is the confluence of I-94, I-43 and I-794 located in downtown Milwaukee, Wisconsin, U.S.A. The new Marquette Interchange is currently being reconstructed as five-levels with all right-side system ramps. The entire Marquette Interchange project is better defined as Milwaukee’s downtown freeway reconstruction, as the project limits and scope include 5.5 miles of interstate, 23 ramps, 2 million square feet of bridge deck and 5 miles of retaining walls. FHWA initiated a road safety audit (RSA) and in December 2003, representatives from FHWA, Wisconsin DOT and Hamilton and Associates conducted a week-long safety audit of the interchange project. Following is a summary of the audit findings and the designer’s responses. Recommendations and suggestions on safety audit best practices are offered for future consideration.
