On Tuesday, June 18, 2019, Washington State Department of Transportation’s contractor, Farline Bridge, Inc., began work to replace the existing, aging State Route 506 - Lacamas Creek Bridge near Vader, in Lewis County, with a new concrete bridge that will serve the community for years to come. 

Needs & benefits

Originally built in 1951, the Lacamas Creek Bridge served as an important connection along SR 506, between Vader and I-5. However, the original bridge was no longer meeting modern bridge standards for functionality and safety and had to be replaced. This project restored the connection along SR 506 by building a new concrete structure that meets current bridge standards and can accommodate all legal loads. 

The new concrete bridge benefits all travelers by improving safety with a wider structure that included better pedestrian and bicycle access.

  • Safety - The new concrete bridge replaced the original timber bridge structure, and meets current bridge safety and functionality standards.
  • Mobility - The new Lacamas Creek Bridge was built with widened with improved bike and pedestrian access, ensuring people of all abilities are connected for years to come.


  • Spring 2019: Project went to competitive bid
  • Summer 2019: Construction began
  • Late summer 2020: The new bridge opened to traffic
  • Fall 2020: Construction was completed 


The total cost of this project was $5,605,616.
