McVey Avenue - pipeline construction complete, testing and disinfecting begins!

Last week construction was action packed on McVey Avenue as crews safely maneuvered cranes and large equipment to install the new pipe bridge support footings and place the final portion of the new finished water pipeline! This is a significant milestone for the cities of Lake Oswego and Tigard, marking the end of two years of pipeline construction, where more than 10 miles of large diameter pipe was installed across four communities!

Thank you for your patience as we have constructed this new, reliable backbone to the most seismically resilient water system in all of Oregon!

Over the next week, crews will continue to weld the pipeline and bridge supports together. Now that the pipe is in place, testing and disinfecting will begin. Crews will fill the 15,000 foot segment of pipe between Laurel Street (at Bullock Street) and Iron Mountain Boulevard (at Fairway Drive) to pressure test the pipe. Once this is done, crews will disinfect the new pipeline, before placing it into service. Neighbors in these areas may notice crews operating equipment and accessing vaults along the pipeline route over the next two weeks.

By early April, the newly installed finished water pipeline, from the treatment plant in West Linn, to the Waluga Reservoir in Lake Oswego and Bonita Pump Station in Tigard will be online!

ADA ramps and final paving - as weather permits

Final restoration and paving remains in some areas where the pipe was installed on McVey Avenue, State Street, Green Street, Ladd Street and Durham Street. ADA ramps will also be installed on McVey Avenue, between the east side of the Oswego Creek Bridge and State Street. Paving work on McVey Avenue and State Street will likely take place at night, to minimize disruptions to traffic.

Paving and ADA ramp work is weather dependent. More information will be provided once schedules are known.
