Old Plank Road

The historic Old Plank Road was built in 1915

Located in Imperial County, the Old Plank Road is a plank road that was built in 1915 over the Algodones Dunes, a large sand dune field in the southeastern portion of the U.S. state of California.

Plank Road was built in the early 20th century to help cars get across eight miles of sand of Imperial Sand Dunes. It was a one-lane road of wooden planks bound together and laid across the sand to make a primitive roadway. The plank road took two months to build and was considered a success even though it needed constant maintenance to keep it clear of sand.
About 3000 vehicles a week traveled across the road that resembled railroad tracks for cars. Turnouts built every mile were added so cars could pass each other on the one-lane road. The road was constructed from planks seven feet long and resembled a railroad track but for autos only. Soon after the plank road was completed the California State Highway Commission took authority for the road and upgraded the route to an 8-foot wide wood roadbed. Turnouts were added about a mile apart in order to let the traffic flow in both directions. In early 1915 workers completed a crude road across the sands east of Grey’s Wells, with two parallel tracks, each 24 inches wide made from 3-inch-by-8-inch wooden planks. As the sand covered the road, a horse team was brought in and the sections were lifted and dusted off and laid back down and traffic resumed. Portions of the plank road were moved by teams of mules when shifting sand made such corrections necessary.

The plank road opened for the first time a direct route for drivers traveling between San Diego and Arizona. The plank road -- the original Route 80 -- lasted for a dozen years until it was replaced by an asphalt road and today's four-lane highway. The first road across the Algodones Sand Dunes was built with funding by Ed Fletcher of San Diego. Today, only fragments of the Plank Road remain. This plank road allowed a direct route through an ever change landscape.The region of towering dunes resembles the Sahara desert has been featured in films ranging from Rudolph Valentino's “The Sheik” to 1983's “Return of the Jedi.”
