Step 1 : Introduction to the question "The first mile of paved concrete street in the world was Woodward Avenue, located in which city?"
The first mile of concrete pavement was placed in Detroit, Michigan on Woodward Avenue. The pavement stretched from Six Mile Road to Seven Mile Road and was built in 1909. The cost at the time was $14,000. Roads up to that point – if they were paved at all – had been built with brick, cobblestone, or a material called macadam, which was not much more than stones sprayed with a tar to form some kind of wear resistant surface. Woodward Avenue would later be one of the first street’s to have a painted centerline and electronic traffic signal.
