Redevelopment of the Georgetown waterfront began in 2008. Though the freeway was last rebuilt in a project ending in 1998, the Government of the District of Columbia has proposed demolishing the Whitehurst Freeway and upgrading K Street to a 4- or 6-lane through street. One engineering difficulty in doing so is to connect K Street to Canal Road, which is about above the waterfront. Another engineering difficulty is to connect K Street to the Key Bridge. To address the latter difficulty, architect Arthur Cotton Moore has proposed replacing the present ramp from the northbound Key Bridge to the eastbound Whitehurst Freeway with a spiral ramp that would loop under the Key Bridge before connecting to eastbound K Street.
