 Up until the fall of 2009, Highway 145's northern terminus was at the freeway interchange with US-41 in Richfield.A project involving the construction of five roundabouts in a less than one mile span has truncated the highway's northern terminus to the freeway interchange with US-45, with the stretch of roundabouts between US-41 and US-45 now designated as County Highway FD.Highway 145 travels generally southeast through Germantown as a secondary highway.
