The Mountain Loop Highway is a scenic highway in Snohomish County, Washington, United States. The highway runs for 55 miles (89 km) between the towns of Granite Falls and Darrington, traversing a section of the Cascade Mountains along the South Fork Stillaguamish River and Sauk River. It is designated as a National Forest Scenic Byway and follows a section of Federal Forest Highway 20 (FFH 20), which is jointly maintained by the county government and the United States Forest Service (USFS).

Route description

[edit]

The Mountain Loop Highway begins in downtown Granite Falls at the intersection of Stanley and Alder streets. The highway travels north on Alder Street and leaves the city, intersecting the terminus of State Route 92 (SR 92), the main driving route to other areas of Snohomish County, near the city's large gravel mine. It crosses the South Fork Stillaguamish River above the eponymous Granite Falls and makes a gradual turn to the east, passing several housing subdivisions and another large mine. The Mountain Loop Highway continues southeast along the river, passing several farms and ranches in the Robe Valley. At Verlot, the highway enters the Mount Baker-Snoqualmie National Forest and becomes concurrent to FFH 20.

The Mountain Loop National Forest Scenic Byway and FFH 20 designations start at the boundary of the Mount Baker-Snoqualmie National Forest in Robe.

Renton S-curves

[edit]

The Renton S-curves[1][2] are a series of curves on Interstate 405 in Renton, Washington that are notorious as a traffic bottleneck.

Definition

[edit]
  • I-405 in downtown Renton, between SR 167 and SR 900?
  • AADT

Causes

[edit]
  • Northbound traffic from SR 167 forced to merge quickly (until 2010)
  • Only 4 lanes until 1995 project
  • Between hill and downtown
  • Closely-spaced interchanges (1/4 mi apart)
  • Obscured sight distances on northernmost part[3]

History

[edit]
Straightening project (1990–1995)
  • 1986: WSDOT proposes straightening of S-curves[4]
    • 425 accidents between 1981 and 1984
    • Construction from 1988 to 1991
  • 1990: Project begins with water main relocation[5]
  • 1995: Widened and straightened segment opens[3]
