Driving Directions
Google Maps recognizes "LIGO Hanford Observatory" as a search term.
Taking State Rte 240: Travel west on State Rte 240 from Richland, then turn right (north) onto Rte 10 (Horn Road) at the roundabout. LHO is about 6 miles north on the left hand side.
Taking Stevens Drive: Follow Stevens Dr. past the generating station. Just before reaching the Wye Barricade gate to the Dep't of Energy Hanford site, turn left to follow the sign for "Rte 10/To 240" onto the short spur road. Turn left again at the stop sign. LIGO is about one mile down the road on the right. If you end up at the Wye Barricade, the guard at the gate will point you in the right direction.
