Mysterious Detour While Driving? It Could Be Due to the Curvature of the Earth

Photographer Gerco de Ruijter's new project explores the places where our highway system goes astray, thanks to the challenges of imposing a rectilinear grid onto the spherical surface of the planet.

When the Dutch photographer Gerco de Ruijter arrived earlier this year for an artist’s residency at Wichita’s Ulrich Museum of Art, he noticed something strange while driving to a friend’s house outside of town. At several points, the rural road he was on came to an abrupt halt at a T intersection in the middle of nowhere, requiring a quick zigzag to continue on the same road. The detour could be anywhere from a few dozen yards to nearly half a mile, but, in every case, there was no visible reason why the road should shift at all. This wasn't the urban street grid of Wichita, throwing a few random twists and turns de Ruijter’s way. It was the large-scale grid of the country itself—those huge squares of agricultural land visible from airplanes—seemingly gone haywire.

De Ruijter soon learned that these kinks and deviations were more than local design quirks. They are grid corrections, as he refers to them in a new photographic project: places where North American roads deviate from their otherwise logical grid lines in order to account for the curvature of the Earth. You could drive out there your whole life, de Ruijter realized, and not realize that certain stop signs and intersections exist not because of eccentric real estate deals, but because they are mathematical devices used to help planners wrap a rectilinear planning scheme onto the surface of a spherical planet. In order to avoid large-scale distortion, the Jeffersonian grid—shorthand for the founding father's 18th-century geometric vision of six-square-mile township parcels, intended to guarantee equal and democratic land-distribution nationwide—is occasionally forced to go askew.
