I was driving along Washington St. (NR, US 40) in Indianapolis recently and came upon some road construction downtown. Some of the road had been cut out in the middle, and it revealed several layers of pavement. One of them was brick, which isn't terribly surprising as newer surfaces are commonly laid down directly over old. But it was nice to see it. I can't entirely tell what layers lurk below, but I do see splintered wood.
Weather and schedule have prevented me from getting onto the road this season, but I want to drive the Michigan Road in Shelby and Marion Counties to make sure the Historic Michigan Road signs are properly placed, and I want to drive the Lafayette Road, an 1830s road connecting Indianapolis and Lafayette. It was four laned in the early 1930s but a couple two-lane concrete bits remain.
