Some of Snohomish County’s bridges will need to be rebuilt or restored in the next few years.
That’s according to a report released by county engineers on Thursday.
The report says that eight were rated ‘poor condition.’ 119 were listed in ‘fair condition’ and the remaining 83 were rated ‘good condition.’
Of the 210 bridges:
- 15 are culverts with spans longer than 20 feet, making them a bridge
- 23 are constructed from steel
- 29 are a combination of wood, steel, and concrete
- 38 are built from timber
- 105 are constructed out of concrete

According to the report, construction projects to replace two of the bridges will begin this year:

There’s also scheduled maintenance work planned for Red Bridge 537 on the Mountain Loop Highway east of Granite Falls.
