American River Metal Debris Study Details Cleanup Costs

Just what to do with hundreds of tons of metal left in the American River after a 1964 bridge washout is still an open question.

But a new report commissioned by the Sierra Nevada Conservancy now has a cleanup plan and an estimated price tag on the work.

The debris from the Highway 49 bridge washout 50 years ago rests downstream from the current Highway 49 bridge – with twisted steel just under the surface of low summer river flows and huge chunks of broken concrete sitting above the shoreline.

Report author David Burns, who is part of a renewed effort to remove dangerous debris from the river, said that while the question of who will pay for the work goes unanswered, the estimated cost to remove all the steel now in the Highway 49 debris field would be about $775,000.
