Jordan Creek Bridge 214 Replacement

Description

Jordan Creek Bridge #214 carries traffic over Jordan Creek near milepost 5.8 on Jordan Road. This bridge is located seven miles southeast of Arlington and serves as a popular residential and commercial route between Arlington and Granite Falls. In June 2019, the bridge was revised to a single lane with new width/weight restrictions. Please check Height and Weight Restrictions for information. 

The existing bridge is a six span, 107-foot-long structure that was last re-built in 1981. This bridge is built on timber piles and needs to be updated to meet Seismic Design Codes. Jordan Creek Bridge is considered a seismic lifeline route structure. Seismic lifeline routes are designated as essential to life safety services after seismic events. Funding for a replacement bridge has been secured and construction of a new bridge is proposed for 2024.

Design

Snohomish County proposes a new design to better accommodate modern traffic loads, future development and seismic events. The proposed replacement bridge will be a 120-foot-long single span girder bridge with two 11-foot wide lanes and six-foot shoulders. The new design will improve mobility for the 1000 daily drivers and short-haul truckers using the roadway as well as pedestrians and bicyclists. 

Traffic Impacts

The single lane revision is only causing minimal delays in peak travel periods.  During construction, a full road closure is anticipated. A detour around the project area will shorten the total construction period, reduce costs and provide a safer environment for motorists and workers. Any closure would be scheduled while school is out of session. This page will be updated with closure dates when they are finalized.

Environmental Review

State Environmental Policy Act (SEPA) Decision: On September 21, 2022, Snohomish County Public Works determined that this project does not have a probable, significant adverse impact on the environment and has issued a Determination of Non-Significance (DNS).

Land Disturbing Activity (LDA) Permit

This project will be reviewed for compliance with Chapter 30.63A (Drainage) and Chapter 30.63B (Land Disturbing Activity) SCC, as well as other applicable regulations in Title 30 SCC. Public Works will exercise its authority under Rule 5001 (Revised 10/2020).

A revised notice of Land Disturbing Activity (LDA) will be published on May 29, 2022 due to design changes. A SEPA checklist has been completed. For more information, please contact Troy.Fields@snoco.org. 

Funding

Snohomish County has secured a Federal bridge replacement grant to pay for part of the cost of replacing the bridge. The Federal grant requires Snohomish County to match 20% of the grant amount. Federal bridge replacement funds will be available in 2020 and construction is planned for 2024.
