SR 272 begins as Canyon Street in Colfax at an intersection with Main Street, signed as US 195. The highway passes Colfax Cemetery before leaving Colfax and traveling northeast along the Palouse River into farmland. SR 272 turns southeast into Palouse, crossing the Palouse River and becoming Church Street before an intersection with Division Street, signed as SR 27. The highway turns south and east onto Echanove Avenue concurrent with SR 27, crossing a Washington State Department of Transportation (WSDOT) rail lube before turning south onto Division Street and splitting off.[3] SR 272 continues east as Main Street and leaves Palouse, traveling northeast over the WSDOT rail line towards the Idaho state line, where the highway becomes SH-6.[4] SH-6 continues east for 5.711 miles (9.191 km) along the Palouse River towards Potlatch, Idaho.[5]
Every year the WSDOT conducts a series of surveys on its highways in the state to measure traffic volume. This is expressed in terms of annual average daily traffic (AADT), which is a measure of traffic volume for any average day of the year. In 2011, WSDOT calculated that between 350 and 2,100 vehicles per day used the highway, mostly in Colfax and Palouse.[6]
