 US 10 was replaced by the western extension of US 2 in 1946 . Three years later , in 1949 , the Spokane River Bridge at Long Lake Dam was constructed and spanned from the southern terminus of SSH 3J to Lincoln County . In 1957 , PSH 3 and US 395 were moved to an eastern route bypassing Springdale , while SSH 3J was extended north towards Chewelah and a branch of the highway was added to Loon Lake , both along the former route of PSH 3 . SSH 3J was extended south to PSH 2 and US 2 in Reardan , east of the northern terminus of SSH 2G , in 1963 . During the 1964 highway renumbering , SR 231 was created from SSH 2G and SSH 3J and became concurrent with US 2 ; US 2 replaced PSH 2 and US 395 replaced PSH 3 , while the branch of SSH 3J to Loon Lake became SR 292 . The Spokane River Bridge was added to the National Register of Historic Places on June 2 , 1995 along with the rest of the bridges on the Spokane River northwest of Spokane , and the bridge was repaired in late 2008 .
