The dirt is still sinking under an unopened portion of Illinois 255, and engineers still haven't identified an exact cause. Last September cracks began forming in the pavement near Seminary Road, preventing the stretch to Humbert Road from opening around last Thanksgiving, as originally planned. An IDOT engineer now says he is hopeful the road will be open by the end of the year.
The sinking pavement problem is isolated to about 400 yards of pavement close to the Seminary interchange. IDOT Engineer Joe Gasaway says this is a problem that has stumped them for months.
Traffic on 255 will continue to exit at Seminary until the final leg of the project is done, which is expected to be late in the year. Gasaway says the public has been patient with the delays, perhaps because they have never had access to this road. He says it might be a different story if they had to close a road that people had already gotten used to driving.
