The key element of this project is the construction of a grade separation structure that will carry the Canadian Pacific Railway over Illinois 19 (Irving Park Road). The new structure will consist of a two-span, steel through-plate girder bridge with a median pier. The structure will be built east of the existing crossing. In conjunction with the new bridge, six new retaining walls will be built to retain the newly elevated railroad embankment and provide for railroad access road turnarounds.
The intersection improvements include widening on all four legs of the current intersection to improve channelization. The proposed intersection will include two through lanes in each direction, single left-turn lanes for the east and west approaches, dual left-turn lanes for the north and south approaches, and right-turn lanes for all but the
east approach. A total of approximately 1,100 ft. of Illinois 19 (Irving Park Road) will be reconstructed with another 750 ft. widened and resurfaced. For York Road, a total of 1,500 ft. will be reconstructed with another 1,300 ft. widened and resurfaced. The reconstructed pavement will consist of 10 in. jointed concrete pavement.
The project includes traffic signal modernization, landscaping, lighting,
sidewalks and drainage improvements. The drainage improvements will include an extension of the existing culvert under York Road that currently carries the Bensenville Ditch. A new culvert is also required under the new railroad embankment to carry the Bensenville Ditch.
The Department let an advance work contract to build a large portion of the Canadian Pacific Railway embankment south of Illinois 19 (Irving Park Road). This project also includes clearing, tree removal, erosion control, and the design and construction of a temporary soil retention system. The construction of this advance work project will be concurrent with the bridge construction project.
The programmed amount for the entire Illinois Route 19 (Irving Park
Road) project is $64 million. The awarded construction cost for the
advance embankment work contract was $1.2 million and $18.5 million
for the bridge contract.
