Transportation / Intersections


Alta Lane and Radnor Road Roundabout / Peoria, Illinois

This  project included a Phase I Study of the intersection included investigation and presentation of numerous alternatives with a capacity analysis performed for each alternative and, ultimately, an Intersection Design Study with IDOT approval for the selected roundabout option.  

Services also included coordination with the City of Peoria, Radnor Township, Peoria County Highway Department and IDOT.  There was also significant coordination with utilities and adjacent property owners including developers.  Phase I  Study included coordination, exhibit and presentation preparation and staffing for two public meetings along with  a Project Development Report for the HSIP funded intersection reconstruction.  

Phase II design of the single lane roundabout consisted of geometric design of the entire roundabout roadway including approaches and splitter islands, drainage design with storm sewer and culverts, signing, striping and lighting, drainage design, along with land acquisition and right of way coordination and assistance.

Parkway Drive and Broadway Road Intersection / Pekin, Illinois

We were retained by the City of Pekin to undertake a Phase I Study and Phase II Design of the federally funded reconstruction of the intersection of Parkway Drive and Broadway Road in the City of Pekin, Illinois.

This project consisted of complete reconstruction with intersection widening, new signal design and extensive drainage improvements to the intersection that experiences a combined average daily traffic of 45,000 vehicles.  An Intersection Design Study (IDS) was prepared and coordinated with IDOT as part of the Phase I Study that also required Section 4(f) public land coordination due to the adjacent Parkview Golf Course.  We also coordinated and held the public meeting required as part of the Phase I Process.  The study also included an in-depth crash analysis to ensure proposed improvements were tailored specifically to the intersection to reduce or eliminate crashes.

New signals were designed at the intersection, along with numerous improvements to the storm sewer system that were identified during the location drainage study for the project.
