Some cities with very cold winters have skyways. Skyways are enclosed, heated bridges that connect tall office buildings. The skyways cross above cold streets and sidewalks, so people can walk from building to building without going outside. Skyways are an extra expense for building owners and builders and can require special engineering. For people too busy and important to bother with a coat, skyways may be seen as worth the cost.
