Lynnwood Link Extension
SUMMER 2018
The Lynnwood Link Extension is a key part of Sound Transit’s mass transit system
expansion approved by voters. Targeted for operation in 2024, four new stations and
8.5 miles of light rail will connect north Seattle, Shoreline, Mountlake Terrace and
Lynnwood with the entire region.
Schedule
At Sound Transit, sustainability is about making long-term investments and choices
that keep the region’s environment, communities and economy healthy. The agency
encourages sustainability by providing affordable, environmentally friendly travel
options that connect people to where they live, work and play.

SYSTEM EXPANSION
Sound Transit system expansion is:
• Building a 116-mile network extending regional light rail from Tacoma to Everett,
and from densely developed Seattle neighborhoods to Redmond and Issaquah,
and extending Tacoma Link.
• Establishing Bus Rapid Transit to the north, east and south of Lake Washington.
• Expanding Sounder south line capacity and service, adding two new stations.
• Improving access and expanding parking at Sounder stations.
TREE REMOVAL AND REPLACEMENT
SUMMER 2018
Starting in early 2019, Sound Transit will begin removing trees in areas where track,
guideway or other transit infrastructure will be located in order to protect safe and
uninterrupted light rail service. Trees could potentially fall onto tracks or disrupt
power service.
Sound Transit is committed to replacing
trees removed during construction based
on replacement requirements in each
jurisdiction. Where feasible, agency crews
will replant short trees under elevated
guideways as depicted in the graphic
above.
Crews will plant additional replacement
trees around the project corridor. The table
below shows the estimated number of
trees slated for removal and the number the
agency will plant as replacements.
Jurisdiction Number of trees to be removed (est.)
Proposed plantings (est.)
Seattle 180 900
Shoreline 550 2,800
Mountlake Terrace 270 950
Lynnwood 350 1,200
WSDOT 3,950 14,550
MITIGATING NOISE
SUMMER 2018
Construction of the guideway requires the removal of some existing Interstate-5
noise walls along the corridor; those will be replaced as needed. Crews will also
place new walls along the guideway at select locations to mitigate noise from light
rail operations and at stations to enhance the patron experience by mitigating noise
from I-5.
Temporary Noise Walls• Temporary removal of existing traffic noise walls during project construction will
be required to make room for work activities and equipment mobilization.
• Crews will replace removed I-5 noise walls with new in-kind walls before the end
of project construction.
• In the interim, the use of temporary noise barriers, where feasible, will provide
partial traffic noise mitigation.
• Specifics regarding locations and duration of temporary noise barriers locations
will be available after the development of a detailed construction plan.
Examples of Sound Curtains
CONSTRUCTION
Selective demolition work Sound Transit has acquired several properties along the corridor.
These properties are needed for construction and transit operation,
and have been brought to Sound Transit’s attention by their neighbors
as potential areas of nuisance now that they are empty. Starting June
2018, we will begin demolishing existing structures and clearing
debris.
Fieldwork This spring, crews have been drilling in the project corridor to locate
utilities and evaluate underground soil conditions for future systems
that support light rail operation. This fieldwork is nearly complete and
helps to pave the way for construction.
Third-party utility relocations Private utility companies, such as electrical, cable and telecoms, will
be moving their infrastructure in advance of construction work in the
area. Contact your utility company if you have any questions about
service interruptions and planned work.
Sound Transit-led utility relocation
Sound Transit will install and relocate utilities in order to remove
infrastructure that may be in the way of upcoming construction, as
well as better align service to the future guideway and stations.
Clearing and grading of vegetationIn advance of construction work, Sound Transit contractors will
remove vegetation to allow space for construction work, equipment
and materials staging, or access to construction areas.
Active construction beginsIn fall 2018, look for specific information about areas of work,
construction sequencing and potential impacts. Major construction
activities are scheduled to begin in mid-2019. At this time, crews
will move large equipment into place, fence in work areas, create
detours around active construction sites.

New bike access to First Avenue Northeast in Seattle Crews will remove bicycle access to First Avenue Northeast from Northeast
115th Street in order to build the new guideway. After construction of the guideway is
complete, the building of a new trail will restore access.
Pedestrian and bicycle access to new Shoreline South/145th Station in Shoreline People who walk or bike to the new Shoreline South/145th Station from the north
will have a new option to access the station. Sound Transit will build a new trail that
will connect Northeast 152nd Street to the north side of the station, running in part
underneath the new guideway.

Ronald Bog improvements The city of Shoreline and Sound Transit propose using an area of Ronald Bog Park for
a wetland mitigation site to replace wetlands affected by light rail construction. Under
the plan, trail enhancements would balance the use of other portions of the park for
wetland mitigation.
McAleer Creek buffered work area The elevated light rail guideway will cross the State Route 104 interchange loop
50-60 feet above the grade of Interstate 5. To support the structure, crews will construct
four columns along the west side of the interchange loop, spaced approximately 120
feet apart. The columns and guideway in this location are within Washington State
Department of Transportation right of way.
