Marine Drive Reconstruction

Marine Drive Project Location

Location Map

Project Update for December 12, 2019

Whatcom County has finalized selection of a consulting engineer, and started design of the project, which includes addition of bicycle lanes, concrete curb/gutter and sidewalk, pedestrian safety enhancements, drainage improvements, and roadway resurfacing. Construction is planned for the summer of 2021.


In the coming months, there will be County staff and contractors on-site gathering additional information for the project's design, which may include geotechnical explorations, environmental assessments, traffic counts, and field surveys. Minor traffic delays may be encountered during this work.

A public open house shall be scheduled for early 2020, once the conceptual plans for the proposed roadway improvements are complete. This will provide an opportunity for the public to review the conceptual plans, provide comments, and ask questions about the upcoming project.

Project Description and Goals

The project's scope is to widen and reconstruct the existing roadway to facilitate the addition of pedestrian and bicycle facilities on Marine Drive between Locust Avenue and Alderwood Avenue.

The goals of this multimodal improvements project include:

  • Widen, reconstruct, and resurface Marine Drive roadway corridor,
  • Addition of concrete curb/gutter and sidewalks on both sides of roadway,
  • Addition of five-foot width bicycle lanes adjacent to travel lanes,
  • Add pedestrian actuated crosswalk signal improvements in the vicinity of the Alderwood Avenue intersection,
  • Increase clear zone design standards safety with relocation of above ground utilities and poles, and replacing existing roadside ditches with tight-line stormwater conveyance system,
  • Improve stormwater management for the roadway corridor.
