Structural concerns with retaining wall prompt further investigation; city encourages people to use different route.

COURTESY MAP: CITY OF LAKE OSWEGO'S TWITTER - The North Shore Road Bridge is closed while structural issues in the nearby retaining wall are investigated. City of Lake Oswego engineering staff found structural issues in the nearby retaining wall of the North Shore Road Bridge, which prompted the bridge's closure Wednesday, July 14.

The bridge, which runs over Lakewood Bay, will be closed until further notice and people are encouraged to use an alternative route. North Shore Road will remain open between Cabana Lane and Lake Shore Road for local access only.

According to Katy Kerklaan, the city's information specialist, the Lake Oswego Corporation alerted the city to the condition of the retaining wall last week. This prompted a preliminary analysis of the area. Kerklaan said the bridge itself is safe, but the retaining wall which supports the approaching roadway to the bridge was "sluffing off/separating from the wall."

The city found cracks and movement in the retaining wall during a recent inspection of the bridge.

Kerklaan said the Oregon Department of Transportation usually conducts bridge inspections every other year and looks mostly at the structure of the bridge, not the roadway. COURTESY PHOTO: CITY OF LAKE OSWEGO - The retaining wall near the bridge has cracks.

"We are investigating the conditions of the retaining wall and conducting a structural analysis over the coming months," the city's engineering website read. "Long-term closure may be needed."

Boating access is still allowed under the bridge, though that may change.

"The City has notified Republic Services and USPS about the closure," the website read. "If you have additional work at your home (landscaping, construction, etc.), please let them know to use an alternate route."

Kerklaan said city staff will continue to keep people updated.

"We know it's an impact with the closure and an inconvenience, but we want to keep the public safe," Kerklaan said. "Hopefully people can maintain patience while we look into this issue."
