Thousands of tires a day pound the pavement of I-80/94 (the Frank Borman Expressway) in northwest Indiana. So perhaps there is no better resting place for 100,000 recycled tires than under the expressway's widened lanes. Shredded and mixed with sand, these old rubber wheel covers were placed under new concrete lanes as the perfect answer to a ground-stability challenge. Scheduled for completion in 2011, there is a $97 million project under way in northwest Indiana widening I-80/94 from six to 10 lanes with continuous ramp lanes. The project extends to either side of the heavily traveled I-65 interchange.
