was completed in 1993. East of Chinook Pass, the roadway begins to parallel the American River northeast to follow the Little Naches River, which becomes the Naches River. After a junction with the other end of the proposed SR 168, named Little Naches Road, the highway exits the Wenatchee National Forest and enters Naches. The byway ends at US 12 in Naches near the Naches Selah Canal. History The first portion of SR 410 that was defined under law to be built by the state of Washington was a state wagon road that extended from a county road in King County to a county road near Naches. The road ran up alongside the White River until it reached the summit of the Cascades and continued traveling down parallel to the American River before ending at the county road connecting to Naches. This road was approved and built in 1897, making it one of the oldest state roads in Washington state. In 1905, the road became known as State Road 1 and was incorporated into the first state highway system. By 1907, the road was named the White River – Natches Road and was shortened to end at Cedar Springs. The rest of the road was transferred to State Road 5, called the Cowlitz–Natches Road, which ran from Napavine to Naches. In 1913, the state highway system was adjusted again, and several new roads were added to the system, including parts of what would become US 410. The Olympic Highway traveled around the Olympic Peninsula and a section from Aberdeen to Olympia was later used as part of US 410. The Pacific Highway would later have a brief concurrency with US 410 from Olympia to Tacoma, and US 410 would later connect to the National Park Highway in Tacoma and follow it to Buckley, where State Road 5, now a secondary highway maintained by the counties, began. From the end of State Road 5 in Naches, the Inland Empire Highway is concurrent with the future US 410 to Dayton, where a branch of the highway travels to Clarkston. State Road 5 became the McClellan Pass Highway in 1919 and was aligned further south to Chinook Pass. The McClellan Pass Highway was renamed the Naches Pass Highway in 1921 to reflect the realignment in 1919. Despite the name, the road did not cross Naches Pass, as no highway ever has. In 1923,
