Spreuerhofstrasse, a 12.2 inch-wide passageway between two houses in the German city of Reutlingen, is in danger of losing the Guinness Book of World Records distinction as the narrowest road on the planet.

The street, built in 1726, is contracting thanks to a leaning wall from one of the houses, The Guardian reports. Despite its draw as a tourist attraction, the street could lose its honorable status by 2013.

The loss would be a major disappointment for locals.

Tanja Ulmer, head of the Reutlingen s tourism office, told the newspaper that if no one can pass through, the street would no longer be considered a street.

"It s is Reutlingen s smallest attraction, but a very important one," she said.
