- This week's traffic impacts
- Crews are building the bridge driving surfaces (decks), and expect to complete both bridges early this year.
- The speed limit on SR 105 is reduced from 55 mph to 25 mph through the project area.
This project will replace the existing SR 105, North River and Smith Creek bridges, and straighten a curved section of the highway to make SR 105 easier to navigate. The new 36-foot-wide structures will consist of two 12-foot-wide lanes and six-foot-wide shoulders.
The new bridges will help improve safety and increase mobility on SR 105 along Willapa Bay between Raymond and Tokeland.
During construction, crews will build a temporary one-lane bridge over Smith Creek, just west of the existing road, while they build a new bridge on the existing highway alignment. The North River Bridge will remain in use throughout construction while crews realign the highway and build the new bridge.
Why is WSDOT
constructing new bridges on SR 105?
The existing bridges were constructed in 1959 of timber trestles.
The bridges are aging and too narrow to accommodate the types or number of vehicles that need to cross them today. They also do not meet current federal seismic, flood, or structural standards.
WSDOT is replacing the existing structures with new bridge spans built of concrete girders. The new bridges will enhance safety and increase mobility on this portion of the Pacific Coast Scenic Byway.
The End Result
Wider, safer bridges that accommodates today's traffic and meets current federal seismic, flood and structural standards.
- Safety: Improves safety and drivability by constructing a wider roadway, and installing concrete road barriers and new bridge railings.
- Mobility: Provides a wider structure for motorists and allows traffic to flow smoothly across the bridges without delay.
- Environmental: Removes approximately 295 creosote treated timber piles from the creek and restores an estimated 319 square feet of streambed.
