Sound Transit Delays West Seattle Link Extension to 2035
- Sound Transit moved the West Seattle Link Extension opening from 2032 to 2035, with construction starting in 2028, per a statement reported 9 September 2026[3]
- The main cause was time spent analysing cost savings, plus a longer schedule for complex work such as bridge construction and an extended tunnel section[3]
- After a September 2024 estimate found the project unaffordable, savings work found over $2 billion in potential cuts, including dropping the proposed Avalon Station[3]
- ST3 (which also funds Everett Link) faces an estimated $34.5 billion funding gap over 20 years, with total cost put at $185 billion by the Seattle Times[3]; The B1M described the programme as a $54 billion railway in 2022[1]
- Procurement for the Duwamish River crossing, SODO Station, and Alaska Junction packages is under way, with West Seattle tunnels and Delridge Station bids in late 2027 and early 2028[3]

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
