Route description

SR 8 leads over 20.67 miles (33.27 km) from US 12 in Elma to a junction with US 101, about 9.5 km northwest of Olympia. The route only crosses another highway between Elma and Olympia, SR 108 in McCleary. The Washington Department of Traffic (WSDOT) found that at the intersection with US 101, more than 17,000 drivers use the SR 8 every day.

The freeway-like section of the SR 8 eastwards towards US 101

From its western starting point at the intersection with US 12 in Elma, SR 8 leads northeast past Downtown Elma and runs parallel to the Chehalis River . After the highway crosses the river twice, the SR 108 road crosses, which heads north to Kamilche , which is west of McCleary. Past Downtown McCleary, SR 8 passes an incomplete clover at the junction with Mox Chehalis Road, from which the freeway-like section leads east, forming the northern border of the Capitol State Forest and then past Summit Lake . From Summit Lake, the road bends northeast and joins US 101, which faces south.

history

Mark of the PSH 9 EG .

Before the system of primary and secondary highways was introduced in 1923, SR 8 was part of the branch line of State Road 9 , from Elma to Grand Mound. In 1937 the section became part of a branch line of the Primary State Highway 9 (PSH 9 EG). PSH 9 EG became SR 8 when the highways were renumbered in Washington in 1964 ; That year the Washington State Department of Transportation (WSDOT) replaced the previous system of primary and secondary highways with the system of state routes that is still used today.

Map from 1964 with the SR 8m leading from Elma to Grand Mound.

On June 20, 1967, US 12 was extended westward from Lewiston , Idaho to Aberdeen , Washington. This replaced the course of the US Highway 410 . Because US 12 used the year-round passable White Pass and SR 8 from Elma to Grand Mound, while US 410 used the Chinook Pass , which was closed in winter , bypassed US 12 both US 410 and today's SR 8. The signage was changed at the end of 1967 , and the bypassed segment of US 410 became the new SR 8.
