Welcome to the US Route 34 Bridge Construction Website!

This project is located in the City of Aurora, 1.5 miles west of Illinois Route 59, where Ogden Avenue crosses the EJ&E/CN Railroad, at-grade. EJ&E railroad was acquired by the CN Railroad according to the 12/2008 ruling by the US Department of Transportation’s Surface Transportation Board (STB). CN Railroad acquired EJ&E to improve rail operations in the Chicagoland area. The acquisition will result in an increase in the number of trains throughout the corridor. The STB stipulated the need for construction of a grade separation structure at this location to mitigate impacts caused by the increased rail traffic.

The project is needed to reduce traffic delays and to support efficient response by emergency service providers. It will address traffic delays and safety concerns due to trains crossing Ogden Avenue at-grade. The project is tentatively scheduled for letting in late fall of 2013 subject to plan readiness, land acquisition and funding availability through our Annual Legislative Appropriations.

A highway overpass structure is proposed to span over the existing and proposed additional second track. The overpass bridge length will be configured to add a third track for Metra’s STAR Line. The proposed bridge structure will be approx. 253 feet long and 97 feet wide.

Project Start: Spring, 2014
Project End: Fall, 2016
Project Cost: $27,000,000
Project Municipality: Aurora
Project County: DuPage

Did you know work zone fatalities are down 29.6 percent compared to 2003? Aggressive law enforcement and awareness campaigns and significant improvements to work zone safety traffic control reduced Illinois work zone fatalities from 44 in 2003, including 5 workers, to provisionally 30 with 3 workers killed in 2010.
So, Give ‘em a brake…slow down for their sake and yours!
