State Route 124 (SR 124) is a state highway in Walla Walla County, Washington, United States. It spans from Burbank in the west to Waitsburg in the east, intersecting U.S. Route 12 (US 12) at both ends. The highway generally follows the Snake and Touchet rivers and intersects SR 125 near Prescott. SR 124 was previously part of two state highways: Secondary State Highway 3D (SSH 3D) from Burbank to Prescott, and SSH 3E from Prescott to Waitsburg. During the 1964 state highway renumbering, sections of both highways were formed to SR 124, which was officially named Ice Harbor Road and designated as a state scenic byway by the state legislature. Route description SR 124 begins at a dogbone interchange with US 12 in Burbank on the eastern shore of the Snake River near its confluence with the Columbia River in Pasco (part of the Tri-Cities). The highway travels east from the interchange onto Ice Harbor Drive after passing Hood Park on the shore of the Snake River and a local branch library. The two-lane road is rural with a speed limit of as it passes north of the McNary National Wildlife Refuge. SR 124 dips northeast and crosses over a set of railroad tracks carrying the Ayer Subdivision of the Union Pacific Railroad north towards the Ice Harbor Lock and Dam. The highway then turns northeast and ascends a ridge that overlooks the Snake River, which continues north while SR 124 travels east through the Eureka Flat. SR 124 descends into the Touchet River Valley below the rolling hills of the Palouse and follows the river east through Lamar and Harsha alongside an abandoned railroad grade. The highway crosses over Lyons Ferry Road with an overpass and intersects the north end of SR 125 on the outskirts of Prescott, approximately north of Walla Walla. SR 124 continues east through Prescott and turns southeast to follow the Columbia Walla Walla Railroad, a shortline railroad connecting Walla Walla to Dayton. At Bolles, the highway turns south to cross over the Touchet River and makes a gradual turn to the east as it approaches Waitsburg. SR 124 travels through the town on West 2nd Street and briefly turns south on Main Street before continuing east for one block on Preston Avenue to the highway's terminus at US 12. US 12 then continues east on Preston Avenue and beyond Waitsburg to Dayton and
