Sewer construction on southbound SE Grand Ave/Hwy 99E begins Friday

A sewer repair project that begins at approximately 6:00 p.m. on Friday, May 30, will require lane restrictions and a ramp closure on SE Grand Avenue/Highway 99E between SE Ivon and SE Woodward streets all hours and all days for two to four weeks. This location is just north of the Ross Island Bridge, before SE Grand Avenue becomes SE McLoughlin Boulevard.

Construction will occur 24 hours a day, seven days a week, while Environmental Services repairs a segment of failing sewer pipe under southbound SE Grand Avenue/Highway 99E. 

The right southbound lane on SE Grand Avenue/Highway 99E will be closed in the construction zone. The SE Ivon Street ramp is expected to remain open for vehicles exiting the highway, but the on-ramp will be closed. Detour signs will direct traffic along SE Division Street to Martin Luther King Boulevard south, which turns into SE Grand Avenue/Highway 99E. 

The traveling public is advised to avoid the area if possible. Motorists should expect significant delays (up to 30 to 40 minutes) due to the lane closure, travel cautiously, and observe all lane closures and directions by flaggers. Motorists wishing to go southbound on Highway 99E are advised to use alternate routes such as Highway 43, I-84 and I-205.
