On May 29, 2008, Loop 20 was to be rerouted south of SH 359 to US 83, with the old route (the original portion) to become Texas State Highway Spur 260.The section from SH 359 to Mangana-Hein Road (7 miles (11 km)) opened in 2011, and as a result, the old route was officially signed as Spur 260.The Texas Department of Transportation's Laredo District is preparing for future growth with plans to upgrade Loop 20 into a freeway by building overpasses at major intersections and constructing frontage roads.As of 2008, TxDOT planned to complete interchanges and overpasses at all of Loop 20's major intersections within the next ten years.An additional interchange at Clark Boulevard, Texas State Highway Spur 400, has been announced by the City of Laredo.
