Bonneville Power Administration (BPA) proposes to remove the three suspension assemblies on existing structure 19/1 on the Sammamish Maple Valley No.1 transmission line. The removed assemblies would be replaced with floating dead-end assemblies. This would thereby convert structure 19/1 from a suspension structure to a floating dead-end structure.
