Bangkok Governor Aswin Kwanmuang disclosed Monday that the online auctions were now ongoing and successful bidders would be named by March.
Aswin said the e-auctions were for the first phase only, which would cover a 14-kilometre stretch from King Rama VII Bridge to the Somdet Phra Pinklao Bridge.
He said the BMA has asked the Interior Ministry to seek a construction budget from the Cabinet. The project is going ahead despite strong protests from environmentalists.
