Previous So. Fork Bridge
The old SR 6 South Fork Chehalis River Bridge was only 22 feet wide, too narrow for the size and volume of traffic today.

New So. Fork Bridge
At 40 feet wide, the new bridge provides plenty of room and increases safety for freight and passenger vehicles alike.

Overview
The South Fork Chehalis River Bridge was originally built in 1925. The old bridge structure over the South Fork of the Chehalis River was only 22 feet wide – too narrow for large vehicles to safely cross the bridge at the same time. When large vehicles needed to cross the bridge from opposite directions, they stopped and waited for an opening. Due to stopped vehicles, rear-end collisions were common at this location, resulting in a designation as a High Accident Location.

This project replaced the narrow South Fork Chehalis River Bridge on SR 6 in Lewis County with a new, 40-foot-wide structure. The new structure consists of two 12 foot lanes with 8 foot shoulders. The replacement bridge allows large vehicles approaching in opposite directions to safely cross at the same time. The new bridge is 40 feet wide; 14 feet wider than the previous structure. Replacing the bridge decreased the likelihood of rear-end collisions.

How You Benefit
Cross GlyphImproves Safety
Replacing the existing bridge reduced the likelihood of rear-end accidents from vehicles slowing down or stopping on the roadway waiting to cross the bridge.
Car GlyphRelieves Congestion
This project provides a wider structure for motorists. This allows traffic to flow smoothly across the bridge without delay.
