 Illinois Route 59 Expansion

 What's New (Updated July 30, 2014)

Paving Begins and Other Updates (Week of July 28)
Almost all of the utility conflicts in the project have been either removed or relocated, and many retaining walls have been erected. Permanent paving has begun in the north section of the corridor from Diehl Road to North Aurora Road, and paving is expected to begin next week in some areas of the south section from North Aurora Road to Aurora Avenue/New York Street. As part of the paving process, the contractor will be sawing joints into the new pavement. This short activity can be noisy and, due to timing requirements, may continue into the night hours.

Side street work is also continuing. Work on Diehl Road is expected to enter the next phase of construction this week, which will mean east and west traffic on Diehl Road will be able to utilize only one left turn lane and one thru-lane when approaching Route 59. The same configuration will also occur on North Aurora Road in the coming weeks where east and west traffic on North Aurora Road will be able to utilize only one left turn lane and one thru-lane. Both configurations are anticipated to remain in place for the rest of 2014.

Work is also advancing on the I-88 interchange, which has had some impacts on tollway traffic and the associated tollway ramps. The ramps are scheduled to remain open for the foreseeable future. They will be closed for a short duration later in the project, and the City will provide more details once it has received the information from IDOT.

All work is weather dependent and subject to change.

I-88 Tollway Reconfiguration (Week of July 14)
IDOT expects to move into the next phase of construction on the I-88 interchange beginning Wednesday, July 16. All ramps and access to the I-88 Tollway will remain open during this portion of the construction project; however changes in lane configurations on the tollway will occur which may cause congestion and delays. Motorists should use caution and plan ahead if traveling in the area.

All work is weather dependent and subject to change.  

Next Construction Stage Begins (Week of April 21)
Construction activity increased in late April as contractors began the next phase of the multi-year project.

This phase of work along the three-mile stretch of road requires reducing traffic to one lane in both directions underneath the Burlington Northern Santa Fe Railway from North Aurora Road to Glacier Park Avenue/Meridian Parkway until this fall. Lane reductions are being implemented at intersections along the corridor, resulting in significant delays to east-west travel along impacted local streets, including Aurora Avenue/New York Street, Jefferson Avenue/Liberty Street, North Aurora Road and Diehl Road.

Those traveling along Route 59 or through any of the adjacent intersections slated for improvement can expect long delays, and motorists should allow more time for traveling in the area or adjust their routes if possible to avoid high-congestion areas.

To ensure the safety of motorists and construction workers, the Naperville Police Department will also be increasing enforcement in the area to ensure motorists are not talking on hand-held cell phones in the construction zone. Violations of this law will result in a minimum first-time fine of $75. Police will also be issuing tickets for construction zone speeding, which carries a minimum first-time fine of $375, and for blocking the intersections, an action which can result in a $120 ticket. Police will also be strictly enforcing the speed limit along the corridor and in adjacent neighborhoods.

 


The expansion project includes reconstruction and widening of Route 59 from Ferry Road to Aurora Avenue/New York Street as well as improvements to the major intersections within that 3-mile corridor, including Diehl Road, North Aurora Road and Aurora Avenue/New York Street. In addition, an innovative diverging diamond configuration will be implemented at the Route 59 interchange with Interstate 88 that will enhance traffic flow on and off I-88. Construction is expected to be complete in the fall of 2015.

Project Overview

Accommodating more than 50,000 vehicles per day, the Illinois Route 59 corridor through Naperville and Aurora has transformed into the economic backbone of the western suburbs due to its popularity as a key commercial destination.  As a result, motorists experience heavy traffic congestion 14 hours each day of the week, including weekends, with delays approaching 30 minutes at the worst periods. In addition, the area has experienced nearly 400 traffic accidents each year.

While the benefits of growth have been great, improvements to the roadway are needed to ensure safety and efficiency for the property and business owners and the tens of thousands of individuals that use Route 59 every day. Based upon analysis of current roadway conditions and public input obtained during the past 9 years, the following key improvements will be made south from Interstate 88 to Aurora Avenue:

  • Additional Through Lanes
    The roadway will be widened to accommodate three through lanes in each direction for the full length of the project.
  • Intersection Improvements
    Additional turn lanes and through lanes at key intersections will be added and existing turn lanes will be extended to accommodate longer traffic queues.
  • Realigned Roadway
    A section between Paxton Drive and Diehl Road will be realigned so that widening of the roadway will occur primarily on the east side of Route 59 to minimize the impact to residential properties to the west.
  • Improved Coordination of Traffic Signals
    Traffic signals will be reevaluated and retimed in conjunction with the new roadway improvements to improve the traffic flow and reduce delays.
  • Access Restrictions
    Access from many of the smaller side streets and driveways will be restricted or eliminated to reduce congestion and improve safety.
  • Improved Bicycle and Pedestrian Facilities
    Sidewalks will be installed along Route 59 wherever practical and a potential bicycle path along one side of the roadway is also being considered.
  • Improvements to the Interstate 88 Interchange
    An innovative diverging diamond configuration will be implemented on the Route 59 bridge over Interstate 88 that will enhance traffic flow on and off I-88. There are many safety benefits (PDF) to this unique interchange. Click here to watch the video of a DDI that currently exists in Missouri.

Naperville's Role in the Project
 

While the Illinois Route 59 Expansion Project is a state-led initiative, the City of Naperville has been very involved in the project since its conception and is taking proactive approaches to keep residents, motorists and others informed about how the project will affect them. The City is working closely with IDOT and surrounding townships and cities affected by the project to ensure the City of Naperville is informed and the project is successful.

The City has an active Work Group assigned to monitor progress of the project, communicate with IDOT officials, and relay vital project information to the community. Because the project will span over a number of years, the City is already identifying opportunities to emphasize safety in adjacent neighborhoods along the corridor that can expect to see an increase in traffic as motorists search for alternative routes to Route 59. The City team has recently reviewed traffic control in various neighborhoods adjacent to Route 59 and identified opportunities to enhance the existing street signage and pavement markings to remind motorists to follow posted speed limits and obey traffic control.  The new temporary ’25 MPH’ pavement markings that were recently installed at various entrances to Brookdale and Kingspointe subdivisions are just one of the enhancements the City is implementing in preparation of the start of construction on Illinois Route 59.
