on the Lake Oswego Interceptor Sewer (LOIS)

The LOIS system will replace the interceptor sewer line, the backbone of the City's wastewater system, located in Oswego Lake. Replacement of the interceptor is critical to ensuring the environmental protection of Oswego Lake and maintaining sewer service for residents. The existing interceptor is undersized, resulting in overflows during heavy rains, and is vulnerable during an earthquake.

LOIS contractors will be closing one lane of northbound traffic on State Street tomorrow to work on a manhole. Drivers are asked to seek alternate routes, if possible, to avoid delays.

Contractors are scheduled to close the lane again early next week to continue work for a day. Signs have been posted near Marylhurst University to allow drivers to find alternate routes.
