Bonneville Power Association—Boyer – Tillamook Access Road

Location: Tillamook, OR

The scope of work consisted of improving 14 miles of access road for BPA crews to maintain transmission lines and poles. The project crossed through numerous and varied public and private lands which required complex coordination, interface, and communication with multiple stakeholders. These included private properties, farms, Forest Service land, and private timber management lands. Catworks performed this work efficiently while remaining respectful and professional.

Five modular bridges were installed to cross streams and to replace culverts and failing improvised crossings, often built of old logs and other various scrap material. Additionally, an 18 foot by 70 foot multi-plate culvert was installed, employing streambed gravel for fish passage.

Work was performed through areas comprising very steep slopes. In some areas, grades of up to 45 percent required the use of specialty equipment such as track mounted material haulers to safely place rock. Local firms were employed wherever possible and provided all material and trucking for the project. CWC values local small businesses and communities and seeks to provide as much benefit therein as practicable.
