- Iron Mountain Boulevard, Twin Fir Road and Upper Drive- permanent striping
- Chandler Road/10th Street - pipe installation has begun

Exploratory digging – Oswego Village Shopping Center
Crews have completed their exploratory digging to locate existing utilities along the pipeline route between McVey Avenue and State Street. During the week of March 16, they will finish this process by digging small holes in the Oswego Village Shopping Center parking lot to locate the remaining utilities that could potentially conflict with the pipeline. Workers will use a vacuum truck, small drill rig and small excavator. The holes will be repaired as work progresses. To avoid impacting shoppers, work will occur between 8 p.m. – 5 a.m. Flaggers will be place to direct traffic around the work area.
Iron Mountain Boulevard, Twin Fir Road and Upper Drive - permanent striping
Most of the permanent road striping has been painted on Iron Mountain Boulevard, Twin Fir Road and Upper Drive. Over the next few weeks, crews will finish striping the traffic circle at Upper Drive and Iron Mountain Boulevard as well as the stop bars for the stop signs, depending on the weather.
Chandler Road/10th Street - pipe installation has begun
Pipe installation has begun and crews are currently laying pipe from Chandler Road to 10th Street (pictured above). Work hours are Monday-Friday, 7 a.m. – 6 p.m. After this portion is complete, crews will progress along A Avenue; between 10th and 9th Street and cross over to 9th Street. Work on A Avenue is expected to begin the week of March 23. Once work is complete on A Avenue, crews will progress along 9th Street, toward B Avenue.
To minimize traffic impacts on A Avenue, between 10th and 9th Streets, work will be conducted at night from 8 p.m. to 5 a.m., Sunday – Thursday. Single lane closures will in place during the nighttime construction, but two-way traffic should be maintained. Equipment will be staged along the shoulders of the road and right-of-way near the work areas.
Please note, Chandler Road and 10th Street between Iron Mountain Boulevard and A Avenue is closed to through traffic during work hours until March 27. Detours are in place directing traffic onto Iron Mountain Boulevard, Country Club Road and A Avenue. Please watch for signage to safely direct you around the closure. During construction, access will be maintained for local traffic only within the closed area.
Highway 43 nighttime construction - permanent trench patch has begun, major pipe installation almost complete
The Highway 43 crew is currently hard at work installing a permanent trench patch over the lane where the pipe was installed. They started working in West Linn and are progressing north towards Lake Oswego. This patch should make the road smoother until the final paving can be done. 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.
The Highway 43 crew continues to work on the pipeline between Arbor Drive and Robinwood Way (pictured above). Only about 70 feet remain and the last stick of pipe will be installed next week! Over the next few months, small crews will continue to work along the pipeline alignment installing valves, drains, laterals; making pipe connections; performing inspections; restoring or removing concrete panels and other miscellaneous work.
Work hours are Sunday –Thursday, 8 p.m. to 5 a.m. Please drive with caution while traveling through these construction zones and be sure to follow the directions given by flaggers during work hours. Steel plates and temporary pavement patches are present, which can leave the road rough and uneven—driving at slower speeds is recommended. These delays are temporary, and we appreciate your patience during this time.
Thank you for your patience during construction on Highway 43.
