Not long ago, farmers who hauled their crops to market built new roads using nearby materials. So it was with a road now called County Trunk Highway (CTH) S in northwestern Racine County, Wis. The north-south highway connects the village of Wind Lake with CTH K to the south, a distance of about 3 miles. The material at hand: sod, with some gravel and granular substances added for strength, before the whole thing was paved over with asphalt. Here's how Racine County repaired and renovated to bring the road up to modern standards.
