Southwest
Arterial
RDG's challenge with the Dubuque Southwest Arterial was to develop cohesive bridge enhancements at key locations along a new six mile arterial on the southwest edge of Dubuque, connecting US Highway 20 to US Highway 151/61. Our designs for the bridge enhancements were inspired by the area's native limestone along with Dubuque's mining and industrial past.
Where the Southwest Arterial (Future US Highway 52) crosses US Highway 151/61 and US Highway 20, the bridges feature gateway arches announcing your arrival in Dubuque. An aspect of this project was the request to establish and coordinate a high level of roadway sustainable design thinking. In response, RDG developed the Southwest Arterial Sustainable Design Scorecard Handbook for use throughout the design and development of the corridor. The handbook incorporates the best, most applicable criteria and thinking from several industry standard sustainable systems.
