Two parts of Pamplona, Spain were separated by a 30 meter (100 foot) change in grade; cyclists and pedestrians used to have to slog up a precarious ramp and stairway. Architects ah asociados designed this "urban elevator" to tie them together. According to Designboom,
The scheme was developed from an initial study – commissioned by the local council – that considered pedestrian mobility within the region. The research looked at various areas of historical accessibility and urban integration problems, and how they could be solved though mechanical and engineering solutions.
