The opening of Illinois 255 to Humbert Road may not be for at least a few more months, as engineers are still trying to figure out why the dirt under newly-laid pavement is giving way. IDOT Field Engineer Joe Gasaway says the problem cropped up in September, and studies are being done to find a fix. In the meantime, crews are making progress on other parts of the project.
The sinking pavement problem is isolated to about 400 yards of pavement close to the Seminary interchange. Although that part of the project is on hold, Gasaway says there is plenty more work for road crews to do.
Crews have been working in the area for nearly two years, widening Humbert, placing the beams for the overpass, doing ramp work, and other projects to get the extension ready for traffic. They are now working on the Route 67 project, and have recently rerouted some traffic to the new pavement poured parallel to the existing roadway just north of Godfrey.
