A $14 million road resurfacing project begins on Chicago's Dan Ryan Expressway tonight.
The repaving project was pushed up by a year on the highway, which sees as many as 60,000 trucks per day, when the road surface started falling apart in January.
According to the Chicago Sun-Times, the top layer of asphalt, made with slag (residue from steelmaking), was expected to last for up to 12 years. But after nine years, the road surface became brittle and water seeped under the pavement, causing a pothole epidemic. Officials hope the new roadway of crushed limestone, steel slag and polymer-modified asphalt mix will eliminate such sudden deterioration and extend the life of the highway by eight to 13 years.
Expect lane closings in both directions between 31st and 99th streets for the next few months. Northbound work will be limited to between 7 p.m. and 5 a.m., while southbound work will take place between 8 p.m. and 6 a.m.
