UPDATED Traffic Advisory: Crews to pave Highway 43 at Portland-Lake Oswego border Saturday morning, May 20

UPDATE (May 19, 2017) - Paving will take place as scheduled but due to high demand for pavement restoration crews, restriping is now scheduled for early June. The current lane restrictions will continue until then.

(May 17, 2017) – Environmental Services advises the traveling public that crews will pave Highway 43 at SW Terwilliger Boulevard at the entry way to Lake Oswego on Saturday, May 20 from 4 a.m. to 11 a.m. One lane will be open in each direction at all times

Once complete, the lane restrictions that have been in place since April for a sewer repair project will be lifted. Paving is taking place about two weeks ahead of schedule.

The traveling public is advised to travel cautiously and to observe signage. The early morning paving schedule was chosen to minimize travel impacts.

Crews have finished installing two manholes and about 80 feet of pipe under Highway 43 between SW Terwilliger Blvd and SW E Avenue. The work is part of the SW Terwilliger Sewer Project to improve wastewater collection in the area and to protect water quality, public health, and our environment.

SW Terwilliger Blvd WILL REMAIN CLOSED from Highway 43 to SW Castleridge Lane until the project is complete, no later than August.
