100 Years of Concrete Roads!

In 1909, the first mile of concrete road in the world was laid on Woodward Avenue in Detroit, Michigan between Six Mile (McNichols) and Seven Mile. It was 18 feet wide (now it gets as wide as 5 lanes in each direction at that location!) and cost a little over $13,000 (around $1 million in today's dollars).

The road was studied by road builders from all over the country to see how the concrete withstood traffic and the elements. It inspired many modern highways to be built!

And it all started in the Motor City itself!
