Clackamas River safety advisory: Old Trolley Bridge showing signs of failure

The Clackamas County Sheriff's Office is strongly advising boaters to avoid passing under the Old Trolley Bridge downstream from High Rocks on the Clackamas River.

The Old Trolley Bridge is located about 1 mile upriver from the Clackamas River's confluence with the Willamette River.

Early this morning (Thursday, March 6, 2014), construction crews working near the Old Trolley Bridge on the Clackamas River observed the bridge piling actually tilting towards Oregon City and downriver. Within the space of a few hours, the top of the bridge piling had moved approximately 4 feet.

Clackamas County engineers were called in to assess the bridge -- and advised that the shift is significant and alarming.

There is a valid concern about the overall stability of the bridge.

The Sheriff's Office Marine Patrol is strongly recommending that boaters avoid passing under this bridge.

There are boat launches above the area at Riverside Park and below the area at Meldrum Bar Park for boaters to use instead.

The bridge is currently owned by Union Pacific. They are aware of the issue, and have engineers evaluating the situation.

Media outlets should contact Brock Nelson, Public Information Officer for Union Pacific.

This bridge is an abandoned remnant of a trolley line operated by the now-defunct Portland Traction Company. In the early 20th century, it connected Oregon City with Portland.
