Harbour Reach Corridor Project

About the Project

The Harbour Reach Corridor Project (HRCP) will construct a new urban arterial connecting Beverly Park Road to Harbour Pt Blvd SW, while modifying the existing road between South Road and Blue Heron Blvd.  The completed roadway will generally consist of one northbound lane and one southbound lane with buffered bicycle lanes, landscape, and sidewalks on both sides of the roadway.  A roundabout (RAB) will replace the intersection at South Road. Due to funding constraints the previously designed RAB at Harbour Pt Blvd SW has been replaced with a four-way signalized intersection and the proposed improvements between Harbour Pt Blvd SW and Harbour Pt Blvd N (North Segment) have been eliminated from the project.

The new roadway improvements are featured in the following links:

Goals and Benefits

Congested State Route 525 is currently the only north-south connection from the southern City limits to SR 526.  The project will add an alternate north-south route through the City, providing increased capacity for vehicles, and significantly improving emergency response times to the south portion of the City.  Another major benefit of the project is the addition of a multimodal connection through the community by providing pedestrian and bicycle facilities, streetscape standards, and traffic calming methods.  Local students attending nearby Schools, employers and employees in the Harbour Pointe business corridor, patrons of the Harbour Pointe Golf Club and users of the Mukilteo Speedway will experience improvements in bicycle and pedestrian safety and mobility.

Public Outreach

Since the Fall of 2016, the City of Mukilteo has worked in partnership with the community to build consensus on the roadway features and priorities for the Harbour Reach Corridor Project.  At each major project milestone, feedback was gathered from the City Council, community groups and the public, and incorporated into the design development process.  This feedback has been invaluable in shaping the vision for the extended Harbour Reach Corridor.

Project Schedule

In the Summer 2016, the City of Mukilteo started Phase I, Preliminary Design of the Harbour Reach Corridor Project.  This effort was completed in June 2017, kicking off the Phase II, Final Design effort, which began in July 2017.  Due to funding constraints the previously proposed improvements between Harbour Pt Blvd SW and Harbour Pt Blvd N (North Segment) were eliminated from the project.  Design efforts were temporarily suspended in November, 2017 and February, 2018 while significant Value Engineering efforts could be performed to explore further cost reductions.

The Final Design of the proposed improvements, between Beverly Park Road and Harbour Pt Blvd SW (South Segment), was completed in March, 2019, with the Environmental Permitting and Right-of-Way (easement acquisition) efforts completed by mid-summer, 2019.  The City advertised the project for Construction in November, 2019, with bids opened on December 18, 2019.  A total of eleven (11) bids were received with KLB Construction, Inc. determined as the lowest responsive & responsible bidder, and by Council action on January 21, 2020, the City of Mukilteo awarded the construction contract to KLB CONSTRUCTION, INC..

A pre-construction (Pre-Con) is scheduled to be held in early April, 2020, with construction activities anticipated to begin in mid-April. Due to the pandemic, it was not possible to hold a ground-breaking ceremony, but planning is underway for a grand opening.




On behalf of the City of Mukilteo, Randall Roberts, Capital Projects Engineer, applied for a Project Permit with the City of Mukilteo on January 24, 2019 for the Harbour Reach Corridor Project. The application became complete on February 14, 2019.

Notice of Application and Optional SEPA Notice – issued February 21, 2019

Note: The City as lead agency expects to issue a Mitigated Determination of Non-Significance (MDNS).  Therefore, the optional DNS process pursuant to Washington Administrative Code 197-11-355 and Mukilteo Municipal Code section 17.84.105 is being used.  This may be the only opportunity to comment on the environmental impacts of the proposal.

Mitigated Determination of Nonsignificance – issued March 18, 2019

Notice of Decision – issued April 12, 2019

CANCELED Appeal Public Hearing – June 25, 2019

Project Funding

In 2017, the City secured $15.1M of State Connecting Washington Funds for the HRCP, and $1M of City traffic mitigation impact fees.  Due to industry escalation in construction costs, the City experienced a shortfall in the project funding at the 60% design phase.  In August 2017, the City applied for an additional $2.8M in grants through the Transportation Improvement Board (TIB), but was unsuccessful in acquiring additional  funding.  Therefore, the previously proposed improvements for the North Segment (Harbour Pt Blvd SW to Harbour Pt Blvd N) were eliminated from the project.

In 2018, the industry continued to reflect rising costs in construction materials and work force, causing a further strain on the remaining budget to fund the South Segment of the project (Beverly Park Road to Harbour Pt Blvd SW).  The City reapplied for a TIB grant in November, 2018 and was successful in securing $2.3M of additional funding for the HRCP.  Additionally, through continued Value Engineering efforts, and a partnership with the Travis Business Park, the City was able to further reduce the project construction costs to fall within available funding for the South Segment improvements.


On April 13, 2020, the City’s contractor, KLB Construction, Inc. began to mobilize on site at the south end of the project (Beverly Park Rd).  On April 24, 2020 the existing Harbour Reach Drive, between South Rd. and Blue Heron Blvd, will be closed to through traffic.  This existing road closure is anticipated to last until early October, 2020, at which time the existing roadway will be reopened for one-way traffic only (southbound HRD to eastbound South Rd).  Clearing operations of the existing trees along the new roadway alignment, between Beverly Park Road and Harbour Pointe Blvd SW, occurred between late April and mid-June, 2020.
