Where did US 79 end in Austin?

Where did US 79 end in Austin after I-35 was built?  I have a scan of a map that shows 79 as far south as 19th Street.  There are no major US route intersections between 19th and the next route marker, which is US 81/290.  Did it end at Bus TX 71?  Or did it just end at an undisclosed location?

Justin has a 1970 Austin map scanned at http://www.flickr.com/photos/fatguyinalittlecoat/6188339909/in/set-72157621784473496/
US 79 was cosigned with US 81/290 along IH-35 to 7th Street on this map, which is where Dale cite's its end point until at least 1979.
