Project Details

Clay Street had a varied 2 lane existing cross section with sections of curb and gutter. The purpose of this project was rehabilitation of Clay Street from Whittaker Street to Red Arrow Highway including a section with total reconstruction and the remainder of the roadway with milling and resurfacing. This 1.2 miles roadway segment included addition of bike lanes, addition of shoulders and improvements to the drainage system along with the roadway reconstruction, resurfacing and some landscaping. The existing roadway was in poor condition due to poor subgrade material existing underneath the roadway structure and poor drainage.

Abonmarche proposed solutions to the City of New Buffalo that would vastly improve the subgrade support for the roadway and keep the roadway from falling apart for many years to come. Abonmarche designed the roadway based on AASHTO and MDOT design criteria for full depth roadway reconstruction which included significant drainage improvements including placement of geogrid and geotextile separator for separation of clay material from the subbase, developed construction plans, obtained bid proposals from contractors, and performed construction administration for the project. Overall, the project was able to solidify the roadway structure, add safe bicycle lanes and shoulders, and improve the overall drainage of the roadway. Abonmarche also coordinated with the property owners, including the City’s High School, which was within the project limits, to ensure that access was maintained.
