HistoryEdit

 
Wadsworth Boulevard (Colorado Highway 121) at Bowles Ave. in Littleton, Colorado.

The name Wadsworth comes from Benjamin Franklin Wadsworth, one of the founders and first postmaster of Arvada. In northwest Arvada, Wadsworth Boulevard passes over Hackberry Hill at the site where a landmark hackberry tree, for which the hill was named, stood before it was cut down to make room for the highway in 1937.
