History
Route 179 was established in 1935 between its current southern terminus at what was then U.S. Route 51 and Illinois Route 45 at Dana. In 1936, the route replaced Route 45 over its entire length between Dana and Route 17. In 1940, Route 179 reached its current length by replacing Route 17 between the junction of the two highways and Route 18. The highway stayed on this route until it was decommissioned between 1993 and 1995. Route 179's former alignment is now part of LaSalle County Route 44.
