Oregon Highway 35 Betterments, White River and Clark/Newton Sites

Oregon Highway 35 Betterments

Project Overview

The Western Federal Lands Highway Division (WFLHD) of the Federal Highway Administration (FHWA) in cooperation with the Oregon Department of Transportation (ODOT) and the USDA Forest Service (USFS) constructed approximately 3 miles of Oregon State Highway 35 Highway 35 in the Mt. Hood National Forest.

Highway 35 is a major state highway providing regional transportation service as well as access to the Mt. Hood National Forest and other destinations. The existing roadway at the White River and Clark and Newton Creek crossings restricted the debris flows and channel movement, resulting in an unfavorable situation for both the road and natural hydrologic systems. Damage caused by debris flows from the slopes of Mount Hood through the White River and East Fork Hood River areas resulted in frequent and costly repairs over the last 20 to 30 years, placing a severe burden on the limited resources available and negatively affecting the natural environment.

Roadway reconstruction work included construction of temporary traffic lanes / lane widening for temporary traffic, construction of road embankment, installation of new bridges and large drainage structures (culverts), the placement of aggregate and asphalt. Debris materials, both naturally deposited and material moved to downstream locations by ODOT during emergency repairs, at White River were removed and used as fill material for the roadway embankment. This area was then shaped to simulate a more natural floodplain condition. The Clark Creek Sno-Park was removed as a part of this action and the wetland area in and around it was restored.
