Rainstorm Express Car Wash, O’Fallon, IL

Summary

Kaskaskia Engineering Group, LLC (KEG) provided survey, civil design, traffic engineering, and land development services for the new Rainstorm Express Car Wash located in the northwest quadrant of the intersection of Frank Scott Parkway (Thouvenot Lane) and Hartman Lane in O’Fallon, St. Clair County, Illinois. The proposed improvements also involved the widening of Hartman Lane north of its intersection with Thouvenot. The existing asphalt shoulder and concrete curb and gutter were removed in order to widen the roadway pavement to allow for two southbound through lanes. Concrete curb and gutter and asphalt shoulder were reinstalled along the new edge of pavement in areas where they appeared in the existing condition.

In support of the TIS, the KEG team completed traffic counting for peak traffic volume times, performed auxiliary turn lane analyses, and prepared an intersection capacity analyses for the intersection of Hartman and Thouvenot.
