Hot and humid Dubai is planning the impossible - to stop its residents sweating.

As part of plans to get the Emirate's millionaires walking more, the Roads and Transport Authority (RTA) plans to build a network of air-conditioned road crossings.

The tube-like crossings will link buildings, roads and subways throughout the urban area - meaning a walk under the hot Middle Eastern sun will no longer require a change of clothes.

RTA chief executive of strategy Abdul Mohsen Ibrahim Younes said the scheme aimed to reduced the reliance on cars and help people avoid traffic jams.

It is not clear when the pilot project will commence or quite how the RTA aims to convince the super-rich to give up their cooled Bentleys and BMWs.
