Northwest Transit Systems Partners (NTSP), a joint venture consisting of STV and Mott MacDonald, will oversee the systems construction of two transformative new extensions of Sound Transit’s light rail system. The team will perform systems construction management services for the $3.7 billion East Link Extension, a 14-mile-long extension connecting Seattle, Mercer Island, Bellevue and Redmond; and the $1.9 billion 4.3-mile Northgate Link Extension between the University of Washington at Husky Stadium, the University District, and the Northgate neighborhood.
Sound Transit estimates that at least 50,000 people a day will use East Link by 2030. Once completed, the extension will be the world’s only passenger light rail service operating over a floating bridge.
Trains for the Northgate Extension, which is estimated to serve more than 60,000 weekday riders by 2030 and connect Northgate residents to Sea-Tac Airport in 47 minutes and downtown Seattle in 14 minutes, will operate in twin tunnels from the University of Washington Station.
“These two extensions will provide commuters with easier, more reliable access to jobs, schools, retail and cultural institutions all across Seattle and the surrounding area,” said John Ponzio, STV vice president.
