US Route 189 runs north-south in western Wyoming and northeastern Utah. The northernmost section in Jackson, Wyoming is concurrent with US Routes 26, 89, and 191. The very northern endpoint sits at the corner of Broadway Avenue and Cache Street in downtown Jackson, Wyoming, where US Route 189 is terminated as 26, 89, and 191 all turn north onto Cache Street, continuing onward. After heading south through Kemmerer, Wyoming, home of the original J.C. Penney store, US Route 189 joins Interstate 80 west through Evanston, Wyoming, into Utah. US Route 189's last stretch deviates from Interstate 80 at Park City to end at Interstate 15 in Provo, Utah, at a point very near a crossing with US Route 89.
My photo for US Route 189 is actually the northern end marker along Broadway Street in Jackson, Wyoming. The photo actually was taken with the aperture pointing east, and the sign faces west. At the signalized intersection in the background of the photo, US Routes 26, 89, and 191 all turn left to continue north into Grand Teton and Yellowstone National Parks, leaving US Route 189 behind. Wyoming refuses to use any widened route markers in their state, even for three-digit numbers like US Route 189 (my photos of US Route 212 and US Route 310 serve as other examples). This photo was taken along the return trip from the Pacific Ocean, on the way to see Grand Teton National Park in August 2018. Back to the nationwide main page. Back to the home page.
