The team will perform systems construction management services for the $3.7 billion East Link Extension, a 14-mile-long extension, 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.
Mercer Island residents — even when driving solo — have had access to I-90's high-occupancy vehicle lanes, however later this year when construction gets underway to add light rail across the I-90 express lanes, that access will go away.
The 14.5-mile light rail extension, one element of a 50-mile system, will connect some of the region’s most populated and fastest-growing areas to Sound Transit’s existing rail system at the International District/Chinatown Station, which runs from downtown Seattle to SeaTac Airport.
Phase I of the contract for pre-construction phase services is for approximately $1 million over a one-year period. Phase II of the contract for construction phase services, if exercised by Sound Transit, is anticipated to have an estimated value to Hill of approximately $21 million over a subsequent four-year period, for a total contract value of approximately $22 million.
