Sound Transit, amidst the nation's largest light rail expansion, has put its sights on a preferred route with station locations for a 9.7-mile Tacoma Dome Extension while announcing the general contractor for the upcoming Downtown Redmond Link Extension.

Sound Transit's Blue Line trains won't travel across Interstate 90 from Seattle to Bellevue until 2023, but the effort to engineer how light rail will make the trip across a floating bridge — for the first time ever, anywhere — has been ongoing for years.

One of the fastest-growing airports in the United States, Seattle-Tacoma International Airport, will soon be the subject of a study to understand the ongoing impacts of the growth on operations at the airport and in the communities that surround it.

The $9.1 billion 20-year, 75-project effort at Vancouver International Airport in Richmond, B.C., hit a major milestone with a steel topping ceremony on the expansion of the airport's International Terminal Building, known as Pier D, one of the key parts of the largest expansion in the project portfolio.

The first 300 ft of Sound Transit light rail track is now laid for the 2.4-mile light rail extension through Tacoma's Stadium District and Hilltop neighborhood.

With trains scheduled to roll along 12 new miles of light rail track in Portland by 2027, planning on the TriMet expansion continues to move forward, both on the proposed route and 13 stations between Portland State University in Southwest Portland and Bridgeport Village in Washington County.

Efforts to replace the 100-year-old Interstate Bridge connecting Oregon to Washington over the Columbia River, however far they’ve advanced in the past, have all fallen short. Now, though, a small bit of life comes back to the bridge replacement discussion.

A planned expansion by the Prince Rupert Port Authority may propel the northern British Columbia, Canada, port into the second busiest in Canada.
