Ciorba Group was selected by the Illinois Department of Transportation, District Two for final design of a major arterial road in Moline Illinois. John Deere Road (IL 5) was originally constructed as a four-lane, divided highway with a frontage road system in the early 1970s.  Today, John Deere Road is the major east-west access to the Moline/Rock Island area north of the Rock River.  It provides the critical link between US 67 to the west and the I-80/I-88 interchange to the east.  With no alternative east-west arterial route for this area, almost all traffic within the area uses John Deere Road.  The land use along the roadway is largely retail businesses with single/multi-family homes immediately north and south of the commercial area.  The closely spaced intersections coupled with the large diversity of vehicle types caused a high level of intersection congestion and delay.

Ciorba Group prepared the final plans, specifications, and cost estimates for widening and reconstructing 2.5 miles of John Deere Road from the I-74 interchange to 70th Street.  The widening improved safety and capacity by adding a third lane in each direction to the mainline pavement.  Dual left turn lanes and a right turn lane were added to four of the six mainline intersections within the project limits.  The frontage road system was not reconstructed; however, geometric improvements were made throughout.  Approximately 0.6 miles of the roadway was raised to mitigate flooding impacts caused by the nearby Rock River.

The project included the reconstruction of fourteen city streets on new and existing alignments that intersect with the IL 5 mainline and frontage roads for a total of 3.2 miles city street improvements. New or modernized traffic signals were installed at ten intersections along IL 5 and the frontage road system.  The existing signalized intersection at John Deere Road and 38th Street was eliminated and replaced with a right in-right out intersection, a new crossover bridge, and a new roadway (41 St Drive connector) connecting to 38th Street.  These modifications greatly improved the capacity of the 38^th Street intersection. To minimize wetland impacts, 2,000 feet of Mechanically Stabilized Earth (MSE) walls were built along the new roadway and bridge instead of earth embankment. The new two span bridge has abutments on spread footings atop the MSE walls.

Other improvements included replacement of all eight across road box culverts and four pipe culverts, extensive drainage improvements including flooding countermeasures, the addition of multi-use paths, and the construction 3,500 feet of retaining walls at five different locations. One of the retaining walls has 2,250 feet of noise wall mounted onto it. Extensive coordination with the City of Moline was required throughout the design.
