Work scheduled to begin on West Linn end of the project Sunday

Photo Credit: SUBMITTED PHOTO - To increase safety and minimize the impacts on traffic and local businesses, most construction along Hwy. 43 between West Linn and Lake Oswego will continue to occur between 8 p.m. and 5 a.m., Sunday through Thursday. Construction is expected to begin Sunday night on the West Linn end of the Lake Oswego-Tigard Water Partnership’s project to install two miles of new water pipeline along Hwy. 43.

Two pipeline crews are working simultaneously on the project. The crew in West Linn will start at Mapleton Drive on Sunday and work north; a second crew began its work at Laurel Street in Lake Oswego last month and is progressing south.

Most of the construction will continue to take place between 8 p.m. and 5 a.m., Sunday through Thursday. In some areas along Hwy. 43, some activities — such as saw-cutting, exploratory digging and temporary paving — will occur between 9 a.m. and 3 p.m., Monday to Friday.

Katy Fulton, the partnership’s citizen information specialist, said two-way traffic still will be maintained wherever possible, except for narrow stretches of Hwy. 43 where single-lane traffic will be necessary. Flaggers will continue to be in place to direct traffic in these areas, Fulton said.

During night work hours, excavators, loaders and dump trucks will travel through the area to deliver and remove pipe, gravel, steel plates, dirt, rock and other materials. Equipment may be stored in the right-of-way during non-work hours.

At times, steel plates will cover trenches in the highway during the day. As construction progresses, crews will patch the pipe trench with asphalt until the road is restored. Once pipe installation from Lake Oswego to West Linn is complete, the roadway lanes where construction has occurred will be restored, including asphalt milling, paving and striping.

While construction is underway, local businesses will remain open and access to those businesses will be maintained. Construction is expected to be complete in late summer 2015.
