Summary
Kaskaskia Engineering Group, LLC (KEG) provided Phase I and II engineering services for Fehr-Graham for the reconstruction of St. Mary’s Road from Neil Street to 4th Street in Champaign, Illinois. The proposed design consisted of the reconstruction of approximately 3,300 feet of Fourth Street.
Project
KEG’s scope included an Intersection Design Study due to the traffic lane reconfiguration of the westbound approach of St. Mary’s Road at the intersection of Neil Street. Improvements also included the addition of an east-west pedestrian movement on the north side of the same intersection. The IDS approval process required heavy coordination with the Illinois Department of Transportation Geometrics Unit because the project required the reduction of traffic lanes to accommodate a pedestrian shared-use path under the railroad viaduct. The lane reductions were necessary due to the limited space between the columns supporting the railroad bridge over St. Mary’s Road.
KEG was also responsible for the design plans and construction documents to upgrade and modify the existing traffic signal system at St. Mary’s Road and Neil Street to accommodate new pedestrian movements at the intersection.
