update, April 2026, 

I just learned of a Dr June McCarroll who also, in 1917, painted a white stripe down the middle of a road in Riverside County California.

the LA Times, Oct 12, 2003: 

In the fall of 1917, she was driving home at dusk after visiting a patient when a truck forced her off a narrow highway into the sand. It wasn’t the first time. The truck driver apparently had difficulty telling just where his half of the unmarked highway ended.

Later, while driving on another, newer highway, she noticed that the road had a definite middle joint where it had been widened from 8 feet to 16. The pronounced center ridge caused cars to stay on their own side. A center line painted down the middle would serve the same purpose

She got down on her hands and knees and painted a 2-mile-long 4-inch-wide white stripe down the center of the road that passed in front of her house on Indio Boulevard.

For seven years, she wrote letters and petitioned the county and state to adopt the white lines.

In 1924, the Legislature authorized the State Highway Commission to paint center lines.

From Doc June’s idea sprang colors, stripes and other markings on streets and highways to enhance motoring safety.

Because Kenneth Sawyer was a govt official, the road commissioner superintendent, his painted stripe was a govt action, Dr McCarroll was a citizen action, and those distinctions are brought up by Weirduniverse.net as significant as to who should get credit for inventing the stripe. 

The California Department of Transportation says June McCarroll had the idea. But the Federal Highway Administration and the Michigan Department of Transportation say two men in Michigan painted centerlines before her.
