Route description

The highway begins as a two-lane highway at an interchange with US 70A/US 79, where it widens to a four-lane highway and US 45W joins the highway. They then pass through some neighborhoods, where they cross over another railroad overpass, before US 70A Bypass/US 79 Bypass come to an end at an intersection with US 70A/US 79, with the Humboldt Bypass, and unsigned SR 366, continuing south along US 45W. The highway now curves to the south and passes through more rural areas, where it has an intersection with SR 152, shortly before coming to an end at an intersection with US 45W Business, with the road continuing south towards Three Way as US 45W.
