Lancaster-Noxon Number 1 Mile 46-50 Access Road Improvement and Bridge Replacement Project
CX(s) Applied: B1.3
Date: 03/16/2010
Location(s): Bonner County, Idaho
Office(s): Bonneville Power Administration

Bonneville Power Administration (BPA) has a need to construct and repair approximately 4.1 miles of access road and build tower landings along the Lancaster-Noxon Number 1 Transmission Line. As a result of wet conditions at the site, there is currently no vehicle access between structures 46/3-50/1 during much of the year. Proposed project work includes: vegetation removal, grading and shaping of roads, installation of geo-textile material, placing and compacting of road surfacing, bridge replacement, and culvert installation. This project is necessary for future transmission system reliability. All work will be in accordance with National Electrical Safety Code and BPA standards.
