A UAE Arabic newspaper reported earlier this week that the RTA is "conducting a study to put toll gates on other new roads in Dubai".
The article also states that toll gates could be placed on Maktoum Bridge, Shindagha Tunnel, Business Bay Bridge and the Floating Bridge.
It is not the first time reports of an expansion of the Salik scheme have surfaced.
In August Saudi daily Arab News reported that the RTA had started work on new toll gates at eight locations in Dubai, including Shindagha Tunnel, Maktoum Bridge, Floating Bridge, Emirates Road, Al-Khail Road, Nad Al-Hamar Road and Business Bay Bridge.
Related, I've heard that Sheik Mo took a look the blueprints for rail system stations, and rejected them. He wants them to be 5 star stations. Perhaps he's serious about the rail system being attractive to all walks of life. That might be what it takes to make it a success. Another example of thinking big being thinking right?
