It takes surprisingly little structural steelwork to hold the weight of a car safely overhead.
Today’s invention helps deal with the shortage of urban parking spaces as well as providing weather protection to pedestrians.
A ramp allows cars (blue) to drive up onto a trackway over the pavement and park.
Another raised lane is provided to allow parked cars to pull out overhead and rejoin the street via a second ramp.
Pedestrians thus are sheltered by the cars themselves and the roadway has an extra lane (yellow) that would otherwise consist of (filled) parking spaces.
