Location Map

Project Update:

  • Design, permitting and real estate work is now complete and work has begun to select a contractor to complete construction of the project.
  • See below for Slater/Jordan Creek mailing #2.
The Whatcom County Public Works Department is planning to replace an existing 10-foot wide by 7-foot tall steel arch culvert under Slater Road at Jordan Creek during the 2017 construction season. The project will include replacing the existing culvert, which is considered a barrier to fish passage, with an approximately 140-foot span bridge.

Location:    Slater Road at Jordan Creek located approximately 800-feet west of Elder Road.

Project Details:     This project consists of replacing an existing deteriorating 10-foot wide by 7-foot tall steel arch culvert under Slater Road at Jordan Creek with an approximately 140-foot span bridge. Work will also include improvements to Jordan Creek to improve fish passage. 

Traffic Limitations:  Slater Road will be closed at this location during construction which is expected to start in the spring of 2017 and run
through late 2017/early 2018. A signed detour route will be in place during construction which will likely include Elder Road, Unich Road and Lake Terrell Road for local traffic and I-5, Grandview Road, Kickerville Road, and Lake Terrell Road for truck traffic. A copy of the preliminary detour route can be viewed at the following link:

Site Monitoring:     Due to the deteriorated condition of the existing culvert this site will be monitored closely over the upcoming fall and
winter to ensure the safety of the traveling public. Should conditions at the site change requiring a closure of Slater Road the signed detour route noted above will be utilized.
