Florida used to have 337 miles of rural brick roads, part of the state highway system, plus an additional 389 miles of county and local brick roads.

Sixty-six miles of the Dixie Highway in Florida was brick and complete in 1916.

Today, 11 miles of that brick road still exists between S.R. 204 and rural Espanola, Fla. The northern two miles of the road are in St. Johns County and the nine southern miles in Flagler County.

The road has a packed-shell foundation, a nine-foot wide brick roadbed, four-inch wide concrete curbs and three-foot wide shell shoulders. The Old Brick Road is still in good shape because that early twentieth century highway paving used vitrified brick, a production process whose high kiln temperatures fuse the clay grains and close the surface pores. That curing creates brick with a crushing strength of 8,000 to 10,000 psi.
