Illinois Tollway | Elgin O’Hare Western Access Project
Designated as a “Project of National and Regional Significance,” the $3.4 billion Elgin O’Hare Western Access Project is delivering two new Tollway’s – the Illinois Route 390 Tollway and the I-490 Tollway – to address the area’s diverse travel needs by improving travel efficiency, providing western access to O’Hare International Airport, creating opportunities for economic development, and enhancing multi-modal connections and reducing congestion. The Patrick led Joint Venture Team provided Phase II contract plans for the Illinois Route 390 Tollway Project from Lively Boulevard to Supreme Drive, including the Busse Road (IL Route 83) interchange. Patrick’s Team of experts provided seamless coordination with the adjacent section teams to develop/design the complex staging required to shift all Thorndale Avenue traffic to newly constructed frontage roads, to vacate the area so that the new elevated tollway could be built and open to traffic the following year. In addition to the design of a new six-lane mainline toll facility with adjacent eastbound and westbound frontage roads, ramps, and the widening and reconstruction of Illinois Route 83, the project included design of eight (8) new overhead mainline bridge structures, including dual structures over Lively Boulevard, IL 83, the Chicago Terminal Railroad, and Supreme Drive.
