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.
