This conceptual drawing shows the Northeast 185th Street overpass. A new pedestrian walkway and bike lanes would connect to the light rail station.

Sound Transit is advertising the first of three large general contractor/construction manager civil contracts for the $1.5 billion Lynnwood Link light rail extension.

Contract L200 will include 4.5 miles of track, an elevated station with a 500-stall parking garage at Northeast 145th, and a retained-cut station with a 500-stall garage at Northeast 185th Street.

The estimated cost is $380 million to $420 million.

Track will run from Northgate Station to Northeast 200th Street in Shoreline. About 3 miles of track would be built at-grade using cut/fill retaining walls. The remaining track would be on elevated guideways. There is a provision for a future station at Northeast 130th Street.

Construction is scheduled to begin in 2018.

Bids for L200 are due Dec. 10. A pre-bid meeting will be held 10:30 a.m. Thursday in the Ruth Fisher Board Room, 401 S. Jackson St., Seattle.

Sound Transit documents show the preliminary engineering drawings were prepared by North Corridor Transit Partners (Parametrix and WSP/Parsons Brinckerhoff), Bolima Drafting & Design, GeoEngineers, GHL Consultants, Grijalva Engineering, Hewitt, Paula Ito CADD Services, Lin & Associates, Northwest Civil Engineers, Osborn Consulting, Perteet, Swift Co. and Triunity Engineering & Management.

The second large GC/CM project is L300, which will build 3.7 miles of track (2.3 miles elevated) to Lynnwood Transit Center, two elevated stations and a 1,650-stall parking garage.

The third project, L800, will install electrical systems, signals and communication systems along the entire 8.5 miles of track.

A smaller fourth project, L100, will install about 1/3-mile of track in Lynnwood.

Lynnwood Link is expected to be operating in 2023. The track will follow Interstate 5 between Northgate Station and Lynnwood Transit Center.

Sound Transit spokesman Bruce Gray wrote in an email that his agency has secured local funding and will be competing for federal grants with the goal of securing them in 2017. He said the official baseline budget will be determined next year as designs are developed.
