Concrete Quiz #1

I'm starting a little trivia fun on the "Concrete Thoughts" blog. Every month or so, I'll post a concrete-themed quiz question. The first person to post the correct answer in the comment or reply area will win an attractive and useful Concrete Contractor coffee mug! (I'll contact you personally after the quiz to get your mailing address.) The first Concrete Quiz question is: What is the name of the oldest concrete street in America and in what city and state can it be found?
