In 1917, on a stretch of road between Marquette and Negaunee known simply as Dead Man's Curve, Marquette County road engineer Kenneth Ingalls Sawyer watched drivers cut to the inside of the turn, drifting into oncoming traffic with deadly regularity. His solution was deceptively simple: he painted a line down the middle of the road and added directional arrows. Drivers stayed in their lanes. The crashes slowed. And within decades, the painted center line had been adopted on highways worldwide. The curve that inspired one of the most important safety innovations in transportation history still exists, carrying traffic along what is now County Road 492.

Sawyer's painted center line worked so well that Michigan adopted it statewide, and other states soon followed. By the 1920s, painted lane markings were spreading a...
