Permanent trench patching to begin next week on Highway 43
Crews have about 70 feet of large diameter steel pipe left to install on Highway 43 in West Linn! The remaining pieces will be installed early next week, between Arbor Drive and Robinwood Way. Crews are currently doing some minor restoration and cleanup work, and removing some equipment to prepare for trench patching.
Starting next week, a paving crew will begin placing a more permanent trench patch over approximately 750 foot portions of the roadway where the pipe has been installed. They will begin at the south end, near Mapleton Drive, and work north towards Laurel Street in Lake Oswego. This is expected to take about four weeks to complete.
Over the next few months, small crews will continue to work along the pipeline alignment on Highway 43 between Mapleton Drive and Laurel Street. Work will include installing valves, drains, laterals; making pipe connections; performing inspections; restoring or removing concrete panels and other miscellaneous work.
Final paving of the lane where the pipe was installed will occur once the construction is complete on Highway 43 and the new pipe is tested and disinfected, likely this summer.
Nighttime work hours are 8 p.m. – 5 a.m., Sunday through Thursday. During construction, in most areas, one lane will be open at a time, with flaggers guiding traffic in each direction. Please drive with caution while traveling through the construction zones and be sure to follow the directions given by flaggers.
Open for Business!
The Lake Oswego Tigard Water Partnership is committed to supporting local businesses during night construction on Highway 43.

Exploratory digging on Mapleton Drive begins next week
Starting in March, a crew will begin preliminary work along the water pipeline route on Mapleton Drive. They will be digging small holes in the right of way to ensure the pipeline does not conflict with existing utilities in the area. Workers will use a vacuum truck, small drill rig and small excavator—neighbors may notice some noise during this time. The holes will be repaired as work progresses. Equipment will be stored on the site at eastern end of Mapleton Drive, where the pipe was installed under the river.
During the next few weeks, crews will also be trimming trees located in the right-of-way along Mapleton Drive.
Work hours are 7 a.m. to 7 p.m., Monday through Friday, and 9 a.m. to 5 p.m. on Saturdays. While the crews work, there will be a single-lane closure to accommodate equipment, but no total street closure. Please watch for flaggers.
