CX-036279: North Bonneville-Troutdale No. 1 and North Bonneville-Ross No. 1 Access Road Maintenance and Impairment Remediation (Update to previous CX issued on March 30, 2026)

Bonneville Power Administration (BPA) proposes to improve and reconstruct existing access roads, construct new access roads, and correct conductor impairments in line miles 1 to 22 on the 230-kilovolt (kV) North Bonneville-Troutdale No. 1 and the 230-kV North Bonneville-Ross No. 1 transmission lines in Skamania and Clark counties, Washington. The proposed access road work is required to ensure vehicles and construction equipment can safely and reliably access structures in the worst weather for maintenance, repair, and operation of both transmission lines, which share a single right-of-way (ROW). The proposed conductor impairment corrections are required to bring the transmission lines into compliance with industry standards, thereby ensuring system safety and reliability
