Plaque Inscription:

This unique plank road, seven miles long, was the only means early motorists had of crossing the treacherous Imperial sand dunes. The 8-by-12-foot sections were moved with a team of horses whenever the shifting sands covered portions of the road. Double sections were placed at intervals to permit vehicles to pass.

Location:  Imperial County.  Algodones Sand Dunes County Rest Area, S side of I-8 (P.M. 77.4), 18 mi W of Winterhaven.   Note: Plaque was removed from rest area and is on S side of Gray's Well Rd, 3.3 mi W of intersection with I-8, 18 mi W of Winterhaven.  At plaque site are examples of the plank road.
