Interstate 182 (I-182) is an east–west auxiliary Interstate Highway in the U.S. state of Washington. The state highway is an Interstate route, traveling around the city of Kennewick, the largest of the three Tri-Cities in Eastern Washington. I-182 passes through the cities of Richland and Pasco, located in Benton and Franklin counties, respectively. The four-lane freeway, which is concurrent with U.S. Route 12 (US 12) for its entire 15-mile-long (24 km) length, begins at an interchange with I-82 in the Horse Heaven Hills and runs through Richland, becoming concurrent with State Route 240 (SR 240). I-182 and US 12 cross over the Columbia River into Pasco on the Interstate 182 Bridge and become concurrent with US 395 before the former designation ends abruptly.
