SR 6 - Rock Creek Bridge East


Nov. 2016

  • Traffic is moving across the new bridge and the speed limit has returned to 55 mph.
  • In Jan. 2015, contractor crews installed eight concrete girders for the new bridge.
  • Construction began in late March 2014.
  • We awarded the construction contract to Scarsella Bros. Inc. on Feb. 3, 2014.

This project helps improve safety and mobility by replacing the existing SR 6 Rock Creek West Bridge west of Pe Ell with a new, wider structure that will have 12-foot lanes and 6-foot shoulders.

Why is WSDOT replacing this bridge?
The existing concrete bridge was constructed in 1924.

The aging bridge is too narrow to accommodate the types or number of vehicles that need to cross it today. It also does not meet current federal seismic, flood, or structural standards. 

The End Result
A wider, safer bridge that accommodates today's traffic and meets current federal seismic, flood and structural standards.

Project Benefits

  • Safety: Constructs a wider roadway, and installs concrete barriers and new bridge railings.
  • Mobility: The wider structure allows traffic to flow smoothly across the bridge without delay.
