City officials in Mesa, Arizona, have mistakenly installed two bus shelters where no buses run. The installation cost $19,000 at a time when the city is cutting its public transit budget to save money. The shelters were installed as part of a $4.6m improvement project finished about a year ago.

Although there is a bus service on part of the road, the vehicles turn before reaching the shelters. And even though the shelters have signs posted saying no buses pass by, people still wait.

"It slipped through all of us and didn't get caught until after the fact," said Ethos Kramer, a Mesa city spokesperson.
