The State Route 519 is a crucial connection from I-5 and I-90 to the waterfront for cars and freight. Kiewit was awarded the $66 million project to rechannel, widen and improve the First Avenue and South Atlantic Street intersection in Seattle. The team constructed an elevated ramp that connects westbound I-90 to the South Atlantic Street overpass and rechannels South Royal Brougham Way Railroad Overpass between Fourth Avenue South and First Avenue South.

In addition, the team closed the at-grade Burlington Northern Santa Fe (BNSF) railroad crossing on South Royal Brougham Way and construcedt a grade separating structure that will cross over the BNSF railroad tracks and connect Third Avenue South to South Royal Brougham Way Railroad Overpass.
