$52M North Aurora Road Project to Replace Century-Old Railroad Bridge
NAPERVILLE, Ill. – Motorists in Naperville and Aurora should prepare for lane changes and delays starting Monday, September 29, as the final phase of the North Aurora Road Improvement Project begins. The ambitious effort will replace a 110-year-old Canadian National/Wisconsin Central Railroad bridge with a modern structure designed to improve both traffic flow and pedestrian safety.
Details of the $52 Million Project
According to the City of Naperville, the project will construct a new bridge spanning five traffic lanes, with added sidewalks, a multi-use trail, roadway lighting, and higher vehicle clearance. Work will also include a pump station to improve infrastructure durability.
Early efforts will focus on land clearing, drainage improvements, and a temporary bridge to keep rail traffic moving during construction. Officials anticipate completion by the end of 2027, barring unexpected delays.
Traffic Impacts and Commuter Guidance
While one lane of traffic in each direction is expected to remain open, intermittent closures will occur throughout the project. Drivers are urged to:
- Watch for workers and equipment in construction zones
- Follow posted detour signs
- Consider alternate routes to avoid congestion
A major detour is expected in spring 2026 to allow for gas line relocation and bridge removal, with details to be released closer to the date.
Funding and Partnerships
The $52 million project is being funded through a mix of local and external sources. Approximately $40 million comes from the Chicago Metropolitan Agency for Planning, IDOT, and other state and federal agencies, while the cities of Naperville, Aurora, and Naperville Township are covering the remainder.
Officials emphasized that the project represents a rare level of cooperation between municipalities and agencies, aimed at solving one of the region’s most pressing transportation challenges.
Looking Ahead
The bridge replacement marks one of the most significant infrastructure upgrades for the Naperville-Aurora corridor in decades. Once completed, the project will improve daily commutes, enhance safety for pedestrians and cyclists, and provide smoother travel across the busy roadway.
For now, residents are encouraged to stay informed on construction updates and traffic changes through the City of Naperville’s official channels.
Residents can expect several months of work ahead, but once completed, the project promises smoother travel and safer crossings. For more updates on Illinois road projects, traffic alerts, and local improvements, follow ChicagoMusicGuide.com.
