I-255 Resurface – Restore - Rehabilitate

IL255 logo

 

Starting in February of 2020, the reconstruction of Interstate 255 is one of the first projects of the historic, bipartisan Rebuild Illinois effort, and fixes a badly deteriorated section of interstate in the St. Louis Metro East area.  While this project will require a complete closure of the interstate to all traffic for one construction season, it enables the project to be completed cheaper, faster and safer.

     * Significantly reduces completion time to 10 months, instead of 4 years.
     * Saves $14 million.
     * Increases worker safety by keeping traffic out of the work zone.
     * Reduces accidents by eliminating the need for work zone lane shifts.

The project consists of rehabilitating and resurfacing approximately 7 miles of I-255 from I-55/70 to Illinois 15 in two sections separated by Interstate 64, with significant bridge repairs, safety improvements and drainage upgrades.  This project will restore the roadway and bridges to a smooth and safe condition for motorists and will support future investment in the region.

As one of the first projects of the historic bipartisan “Rebuild Illinois” effort, this project fixes one of the state’s worst stretches of roadway.

WHEN WILL THIS PROJECT START AND HOW MUCH WILL IT COST?
This project was on the Nov. 8, 2019, letting and was awarded to the joint venture of The Kilian Corp. and Keeley & Sons Inc. with an apparent low bid of $67 million. Construction activities are expected to begin in  early 2020. The work will be completed in two sections: the North Section, from I-64 to Collinsville Road, and the South Section, from  the Illinois 15 interchange to I-64. Each section will be closed for approximately five months. Some patchwork will occur along the South Section prior to the northern closure to ensure and extend the ability of that section to handle traffic.  Work will start on the North Section in early spring with the full closure (all lanes) of I-255 between I-64 and I-55/70. Full closure of the South Section, between I-64 and Illinois 15, will start after the North Section is complete. IDOT will provide signed detour routes utilizing I-55/70 to and from I-64.  Local traffic is expected to use alternate state routes to bypass the closure.

WHY AN INTERSTATE CLOSURE?
IDOT has determined that an interstate closure is the best construction method to use for this project because it ensures the safety of both the workers and the motoring public. An interstate closure eliminates potential conflicts a motorist might have because of lane shifts, crossovers and emergency closures. Most importantly, an interstate closure maximizes safety for the men and women who will work on this project. This construction method also provides significant cost and time savings. By closing this stretch of I-255, IDOT is able to save approximately $14 million.  These cost savings allow us to use these funds elsewhere within the region on other critical infrastructure projects. It also allows the work/project to be accelerated and compressed into one construction season, and it also reduces the overall construction time for a project of this size from four years to 10 months.

Benefits from complete lane closure include:

  • Completion of the project in 10 months instead of 4 years.
  • Save taxpayers $14 million, plus the ongoing costs of repairing lanes that would stay open with staged construction.
  • Eliminate lane shifts for new configurations, thus reducing accidents and driver confusion.
  • Ensure the safety of workers during construction by keeping traffic out of the work zone.

February, 2020:

On February 1st, the portion of I-255 from I-55/70 to I-64 was closed for a complete rehabilitation of the interstate.  Work began immediately after the closure. For the first week of the project, there were over 4800 hours logged in and an average of 73 on-site workers per workday.  Over the next few weeks, we anticipate that teams of construction workers will be out there rehabilitating the bridge structures and roadways to create a safe and smooth interstate for the Metro-East area commuters.
