Abstract

America's first mini-roundabout opened to traffic May 30, 2001, at the corner of Creyts Road and East Road, in the Village of Dimondale, Michigan: a suburb of Lansing. This report describes Dimondale's project development effort, public involvement and acceptance, crash and delay performance, construction and maintenance issues, costs, and cost/benefit analysis. This paper is not intended as design guidance, but to share the lessons of this initial experience. The authors hope that other practitioners considering roundabouts in low-speed locations with constrained right-of-way - and constrained budget - will find this information helpful.
