LOT Highway 43 pipeline near halfway complete


Project targeted for completion this summer

If you frequently drive on Highway 43 between West Linn and Lake Oswego, you might be growing weary of the bumpy roads and nighttime congestion caused by the Lake Oswego-Tigard Water Partnership (LOT) pipeline installation.

The good news is that, with the overall project just past its halfway point, the pipeline installation on Highway 43 is also nearly half done at 46 percent as of Jan. 16.

“The contractor has installed roughly 46 percent of the pipe on Highway 43, or 4,800 linear feet of the total 10,500 feet,” LOT spokesperson Katy Fulton said. “About 1,300 linear feet, or 17 percent, has been installed within the West Linn City limits on Highway 43, between Mapleton Drive and Cedar Oak Drive.”

The pipeline installation is just one facet of the $250 million LOT project, which was designed to upgrade and increase system capacity to deliver drinking water from the Clackamas River to Lake Oswego and Tigard, while also serving as an emergency water provider for West Linn.

The finished pipeline on Highway 43 will carry treated water from West Linn to Lake Oswego and Tigard. It is on track to be completed at some point during the summer of this year, according to Fulton.

“This part is on schedule,” she said. “They’re making good progress and have been really happy with how they’re working along.”

Construction of the pipeline takes place between 8 p.m. and 5 a.m. Sunday through Thursday, and generally progresses between 50 and 100 feet each night, according to Fulton.

As Fulton spoke on Jan. 16, construction had just passed the intersection of Cedar Oak Drive and Highway 43.

And those steel plates that make for bumpy driving? They’re meant to serve as placeholders, according to Fulton.

“They excavate the trench, install the pipe and then backfill and put in temporary pavement,” Fulton said. “They have to keep the location of where they put the last piping, so they put steel plates there.”

LOT has worked to keep two-way traffic moving through the construction areas, and has also utilized two different crews working toward each other — one in Lake Oswego, working south and the other working north from West Linn.

“(The contractors) have indicated that around maybe March, they’ll go down to one crew,” Fulton said. “Eventually, they will get to close to one another to manage work and traffic flows. So there could just be one crew working on the pipe, and another working on small things.”
