Stacy and Witbeck/Kuney JV selected for light rail extension in US


Stacy and Witbeck/Kuney joint venture has won a contract from Sound Transit to complete the final design and construct the Downtown Redmond Link Extension in Washington, US.

Under the terms of the contract, worth around $730m (approximately £592m), the joint venture will extend the Blue Line 3.4 miles from the Redmond Technology Station by adding two new stations at SE Redmond and Downtown Redmond.

Sound Transit board chair and Redmond Mayor John Marchione said: “Thanks to strong partnerships between the City of Redmond, Sound Transit and our other regional partners, Redmond will soon be connected to the region via light rail.

“Redmond residents and visitors will benefit from fast, reliable transportation to destinations throughout the region.”

The design-build contract involves the completion of final design and construction of 3.4 miles of light rail guideway connecting to the existing Redmond Technology Station and extending to Downtown Redmond.

The contract includes design and construction of two stations, a 1,400-space parking garage, overhead catenary system, traction power substations, train control and communications, special track work, utilities, as well as street and trail improvements.

The board has also approved an allowance of up to $50m (£40.5m) and authorised the team to review alternative concepts received during the procurement process.

The alternative concept allowance will fund selected elements that add value, but may increase project cost if included in the contract.

Sound Transit is also working to extend light rail in all four directions, opening new stations to create a 116-mile regional system by 2041.

From 2021, the Northgate project will add three stations to the Red Line to provide congestion-free travel to Seattle’s University District, Roosevelt and Northgate neighbourhoods.

In 2023, the Blue Line will be opened to Mercer Island, Bellevue and Redmond’s Overlake community. Additional extensions to Shoreline, Lynnwood, Mountlake Terrace, Federal Way, Kent/Des Moines and downtown Redmond are planned in 2024.

Light rail extensions are planned for West Seattle, Fife and Tacoma in 2030; Ballard in 2035; Paine Field and Everett in 2036; and South Kirkland and Issaquah in 2041.

The agency is also working on additional investments to expand Sounder South service and bus rapid transit service in 2024 along the north, east and south sides of Lake Washington.

Sound Transit CEO Peter Rogoff said: “Today we are another step closer to reliable, congestion-free travel to downtown Redmond, and throughout the region.

“When Downtown Redmond Link opens as an extension of the Blue Line in 2024, light rail will extend from Redmond, to Bellevue, Seattle, Lynnwood, and Federal Way.

“With connections to bus rapid transit and local transit services, people will enjoy increased mobility across a greatly expanded transit network.”
