Tree trimming along the transmission line from Murden Cove Substation to Port Madison Substation will start as soon as mid-December

To maintain safe and reliable power, PSE’s service partner, Asplundh Tree Experts LLC, will trim trees for routine maintenance along the transmission lines that serve Bainbridge Island. Crews will start trimming trees along the Murden Cove Tap transmission line between the Murden Cove and Port Madison substations, starting as soon as mid-December. Crews will work in the road right of way from the Murden Cove Substation on Sportsman Club Road to Madison Drive NE to NE Day Road and the Port Madison Substation on NE Day Road located west of State Highway 305. This work is expected to take approximately two weeks to complete. After completing work in this area, they will continue tree trimming for routine maintenance on other circuits located throughout Bainbridge Island until mid-2024.

For safety, crews may temporarily close a traffic lane near the tree trimming. Flaggers would direct traffic around the work area and could hold traffic for a few minutes. Please expect some minor traffic delays near the work area. Crews typically work between 8 a.m. and 4 p.m. Monday through Friday. If you have questions about this tree trimming work, please contact PSE’s certified arborist and project manager at
