Project Overview

What is the project?

After the Northgate extension opens in 2021, the Lynnwood Link Extension extends light rail into Snohomish County, serving four stations, Shoreline South/145th, Shoreline North/185th, Mountlake Terrace and Lynnwood City Center. Upon opening in 2024, riders will enjoy fast, frequent and reliable service between south Snohomish County and the University of Washington, downtown Seattle, the Eastside, Sea-Tac Airport and more.

Funding

In early September 2018, Sound Transit announced welcome news from the Federal Transit Administration (FTA) indicating the agency's allocation of $100 million in FY 2018 capital investment grant funding for the Lynnwood Link light rail extension. The $100 million in FY 2018 funding for Lynnwood Link follows $100 million in FY 2017 funding that was appropriated by Congress. In early November 2018, the FTA signed off on a long-sought grant and sent the agreement to Congress for a required 30-day review. On December 19, 2018, the FTA executed the $1.17 billion Full Funding Grant Agreement.

On December 19, 2018, the U.S. Department of Transportation’s Build America Bureau also executed a $658 million low-interest loan supporting the Lynnwood light rail extension. While the loan will need to be repaid, it cements further the federal government’s commitment to the regional transit authority’s northward expansion.

Sound Transit applauds the administration and congressional delegation for its work to finalize the $1.17 billion full funding grant agreement. The grant will cover roughly a third of the $3.26 billion needed to extend service from Northgate to Lynnwood. The amount includes financing costs, rail car purchases and some maintenance expenses.

Partners

Sound Transit partners with several municipalities, agencies and organizations throughout the Lynnwood Link corridor to ensure this project best fits the community and any other related projects or improvements.

The 8.5 mile project is split into two construction contracts. The southern portion of the project will be constructed by a joint venture of Stacy Witbeck/Kiewit/Hoffman while the northern segment will be constructed by Skanska Construction.

Bus Rapid Transit: SR 522 / NE 145th

Currently in the planning phase, SR 522 / NE 145th Bus Rapid Transit (BRT) will provide fast, frequent and reliable bus-based transit service from north Lake Washington communities to the future Shoreline South/145th light rail station. Buses will run every 10 minutes during the busiest times of the day and the project includes nine stations with additional parking in Lake Forest Park, Kenmore and Bothell.

Bus Rapid Transit: I-405

Currently in the planning phase, I-405 Bus Rapid Transit (BRT) will connect communities along I-5, I-405 and SR 518 from Lynnwood to Burien. With buses running as often as every 10 minutes, this new service connects to Link light rail at Lynnwood, Bellevue and Tukwila as well as to other transit service provided by Sound Transit, Community Transit and King County Metro. The project includes a new transit center in South Renton and 11 BRT stations, three of which add parking. I-405 BRT builds upon the Washington State Department of Transportation's I-405 Master Plan with roadway improvements for faster travel.

City of Shoreline SR 523 (N/NE 145th Street) & I-5 Interchange Project​

The Interchange Project, which is currently under design, will reconfigure the bridge deck to improve traffic flow, and will also build appropriate pedestrian and bicycle facilities with connection to the future light rail station. ​

SR 523 (N/NE 145th Street), Aurora Avenue N to I-5​

This part of the 145th Corridor is currently under design and will add safety and operational improvements including left turn lanes, street lighting, relocated utilities, a shared-use path in some sections and sidewalk improvements with off-corridor bicycle facilities in others. This area will be further segmented into separate projects for construction. The segment from I-5 to Corliss Avenue will be the first segment to be built.​

City of Shoreline 185th Street Multimodal Corridor

The City has been preparing for many years for the scheduled opening of the light rail Shoreline North/185th Station in 2024. Between 2013 and 2015, the City engaged the community in the development of the 185th Street Station Subarea Plan. In March 2015, Shoreline’s City Council approved zoning updates for the 185th Street Station Subarea. Now, the City is undertaking the 185th Street Multimodal Corridor Strategy (185th MCS) to engage the community in the creation of a vision for the 185th Street Corridor. A variety of outreach events and activities will be used to engage and inform the community throughout the 185th MCS process.​
