So the new walkway linking the Metro Station at Dubai Mall/Burj Khalifa is now open so that you can comfortably walk from the station to the Mall without having to go outside. Previously it was necessary to either walk the approximately 1km to the mall from the station or else get a feeder bus to take you there. Now you can go straight there and this is likely to increase footfall in the Mall itself. The walkway has been under construction since last year and is 885m long.
