By 1947,[2] it had been rerouted to run concurrently with US 95, as the majority of its former route had been replaced by the western extension of US 2 from Bonners Ferry, Idaho, to Everett, Washington.

At the intersection, US 195 terminated, and US 10A would follow the shore of Lake Pend Oreille, serving the communities of Hope and Clark Fork before entering Montana.

US 10A was formed in 1941 as an alternate route of US 10 going through northwestern Montana, northern Idaho, and central Washington.

[4] It served as an artery to isolated communities in those states, such as Clark Fork, Idaho; Plains, Montana; as well as several small towns in central Washington.

The proposal resurfaced during the committee's meeting on December 20, 1946, and US 2 was approved as a replacement for US 10A from Everett to Sandpoint and US 195 from Spokane to Newport; however, US 195 would remain on road maps in Washington until at least 1951.

Both highways were a part of a series of similarly numbered routes in Minnesota and North Dakota with the end goal being a unified federal designation.
