A portion of state road 1 built in 1921 has been preserved in Milton Florida. Portions of it are bicycle only and a portion of it is a residential street coming off highway 90. This is one of the better brick roads I have ever traveled. I had no problems at 20mph on the bicycle. It is quite impressive the road is still flat. It is mid summer so the grass is dead. https://commons.wikimedia.org/wiki/File:Milton_FL_SR1_sign01.jpg
