Did You Know that America’s First Highway Was 540 Miles Across Texas?
Did you know the oldest highway in the U.S. was blazed in 1691 and stretched across The Lone Star State out of San Antonio, TX?
Called The Old San Antonio Road it's beginnings date back to the 1690s with much of it based on traditional Native American trails and it was more a network of trails than as single road.

Today much of The Old San Antonio Road is on private ranches. In 1918 inscribed granite markers were installed along the highway. But as of 2006 only nine of the 123 markers still stood and many had been moved from their original locations "as the route of the road was straightened by new highway construction."
According to TXDot: "Old San Antonio Road, or El Camino Real (The King's Highway) is the oldest highway in the United States. It was blazed in 1691 between the Spanish missions of Texas and Louisiana. In Texas, it was 1,000 wide and extended 539 miles from the Sabine River to the Rio Grande. At a width of 1,000 varas, it was wider than three football fields end to end."
In 2004 President Bush signed a bill that designated The El Camino Real de Los Tejas, of which the Old San Antonio Road is part, a National Historic Trail.
