Most of the moai at the ahus weigh 10 to 20 tons, but as many as 40 others weigh 40 to 90 tons. Along certain road segments, long rock alignments appear to be curbstones. These are most common where the roadway slopes upward. These roadways have not been firmly dated, but Love estimates the statue-moving activity ended about A.D. 1500. Most likely, they changed methods of moving these statues as they carved larger and larger ones through time, and the road form depends on the maximum weight of the next statue to be moved on the road.
Love hopes to return to Easter Island for a more detailed examination of the moai roads.
