Washington DC Silver Line Phase 2 (2022)
2013-2022What Happened
The 11-mile extension of Washington Metro's Silver Line to Dulles Airport was awarded in 2013 with a 2018 target. Defective concrete panels at five stations, water infiltration issues, and contractor disputes pushed the opening to November 2022βfour years late. The project cost roughly $3 billion.
Outcome
Metro faced criticism for oversight failures and the lengthy delays frustrated commuters and airport travelers.
The extension now provides direct rail access to Dulles International Airport and has spurred development in Loudoun County, though ridership recovery post-pandemic remains slow.
Why It's Relevant Today
Like the D Line, the Silver Line faced multi-year delays and significant cost overruns during construction. Both projects demonstrate the difficulty of completing major subway extensions on time and budget in the United States.
