| Description: |
The work consists of grading, drainage, base, paving, structures, and other smaller items of work.Project length: 4.906 miles•Clark-Newton Section –This section begins at MP 68.6 and continues approximately 2.9 miles to the Teacup Recreational Area. Work consists of grading, drainage, base, paving, riprap, and structures. There is one single-span bridge across Clark Creek and seven large concrete box culverts for drainages crossing Hwy 35. The project will raise the grade of the road approximately four feet throughout most of the project length. No work will be done on the bridge crossing the dry Newton Creek channel at MP 68.0. The Clark Creek Sno-Park will be decommissioned and wetland restoration of the area will be part of the project.•White River Section –This section is also located on Highway 35 beginning approximately one-quarter of a mile before Forest Service Road 48 (MP 62.4) and continuing across the White River (MP 62.0) approximately 1 mile (MP 61.2), which is approximately one-half mile beyond the entrance to the Boy Scout Camp. Work consists of grading, drainage, base, paving, riprap, and structures. There is a three-span bridge across White River, a two-span bridge across Green Apple Creek (MP 62.1) and large culverts at North Mineral Creek (MP 61.8) and South Mineral Creek (MP 61.6). The project will raise the grade of the road approximately 15-feet above the current White River bridge. Debris material from previous White River events, above and below the bridge, will be used to construct embankments on both sections. Aggregate for base, paving, and rip-rap will come from the Tamarack Quarry, located near Trillium Lake, approximately 8 miles from the project site.Highway 35 is an important freight route for the State of Oregon and the Northwest. Throughout the project, traffic must be maintained at all times. Cumulative construction-caused delays to public traffic must be limited to no more than 30 minutes. Cumulative delay is the total delay caused by construction related operations along the entire project length. Temporary lane widths must accommodate large highway vehicles. During winter closures all recreational facilities must have full access. In addition, construction equipment and materials must be removed from the roadside, Sno-Parks, and parking lots. |
