Highway 43 nighttime construction - concrete panel removal, major pipe work complete
Last week, crews installed the final piece of 48-inch steel pipe on Highway 43 (pictured above!
Beginning Sunday night, crews will remove several concrete panels along Highway 43 between Laurel Street and Burnham Road. Work hours are Sunday –Thursday, 8 p.m. to 5 a.m. Crews have saw-cut portions of the road in preparation for removal, however, the pavel removal work will lead to an increase in noise during work hours. From the end of March through mid-April, crews will also replace concrete panels near the intersection of Mapleton Drive and Highway 43. During this time, steel plates will be present in the roadway while the concrete cures.
Highway 43 crews continue to install a permanent trench patch over the lanes where the pipe was installed. They began in West Linn, working towards Lake Oswego, and paving is currently just north of Glenmorrie Drive. 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, likely this summer.
Over the next few weeks, small crews will continue to work along the pipeline alignment installing valves, drains, laterals; making pipe connections; performing inspections; and other miscellaneous work.
Please drive with caution while traveling through these construction zones and be sure to follow the directions given by flaggers during work hours.
Exploratory digging in downtown Lake Oswego complete – pipe bridge work begins in May
Crews have completed their exploratory digging to locate existing utilities along the pipeline route between McVey Avenue and State Street, including the Oswego Village Shopping Center. In May, crews expect to begin construction of the pipe bridge over Oswego Creek, near McVey Avenue, excavating rock and pouring the bridge’s footings. This work will be done during the day between 9:30 a.m. and 7 p.m.
Traffic circle at Upper Drive and Iron Mountain Boulevard – permanent striping
Crews expect to finish striping the traffic circle at Upper Drive and Iron Mountain Boulevard as well as the stop bars for the stop signs on Twin Fir, Upper Drive and Iron Mountain Boulevard this week. They’ll also put down temporary traffic markings on Chandler Road.
A Avenue night construction – pipe installation finishes this week
Pipe installation on A Avenue is underway and crews expect to be finished by the end of this week. Work hours are 8 p.m. to 5 a.m. Single lane closures are in place during this time.
9th Street construction - pipe installation begins next week
After the work is complete on A Avenue, crews will switch back to daytime construction and progress along 9th Street towards B Avenue. Work hours on 9th Street will be 7 a.m. to 6 p.m., Monday through Friday. Equipment will be staged along the shoulders of the road and right-of-way near the work areas.
During work hours, 9th Street between A and B Avenues will be closed to through traffic. Please watch for signage directing you safely around the closure.
