The Seattle Center Monorail station, a landmark that has greeted fairgoers and commuters since the 1962 World’s Fair, is undergoing a $23 million modernization that broke ground this month. Crews will spend the next 15 months rebuilding the aging structure while keeping at least one train running at all times, meaning daily riders and event crowds headed to Climate Pledge Arena won’t lose service during the work.
The scale of the project reflects just how much the 0.9-mile line has grown beyond its original novelty status. According to Seattle Center, annual ridership topped 2.2 million passengers in 2025, a trend fueled by expanding regional light rail connections and a busier campus event calendar. The 74-acre Seattle Center grounds, home to Climate Pledge Arena, MOPOP, Pacific Science Center and the Space Needle, draw nearly 12 million visitors a year, per the same report.
Randy Engstrom, acting director of Seattle Center, said the project will keep the station safe, accessible, and welcoming as demand keeps climbing. He added that the improvements will help every visitor move through the campus comfortably while preserving its history and character, and that the effort is meant to strengthen the region’s cultural life and prepare the campus for growing activity.

The scope goes well beyond a cosmetic refresh. Per Seattle Center’s Center Spotlight blog, crews will build a new accessible entry ramp from Thomas Street, resurface the platform to narrow the gap between train floors and the boarding area, extend roof coverage, and install updated skylights. The city has also confirmed the work includes removal of lead paint from the aging structure, along with a station layout compliant with the Americans with Disabilities Act, reconfigured ticketing and boarding areas, automatic passenger gates, restoration of the station’s original structures, and maintenance to guardrails, according to KIRO 7 News. The city has said the upgrades are intended to increase accessibility and improve safety at the decades-old station…
