Metro's Silver Line could be facing another substantial delay in its much-anticipated opening that could push its opening into the spring of 2014.
During a Metropolitan Washington Airports Authority meeting Wednesday, MWAA's CEO Jack Potter said that completion of the project could be delayed by at least eight weeks.
Additional safety and performance testing is necessary before the line is transferred to WMATA's authority, MWAA says.
Potter said that there are "real questions" as to when the Silver Line would actually be ready for passengers, according to the Washington Post.
"Any project this large and complex is inevitably going to encounter unexpected issues that require additional tests and adjustments," Potter said in a statement. "With Phase 1 of the Silver Line nearly complete, there isn't sufficient time in the schedule to recover from recently identified matters within the original plan."
The original target date to open Phase I of the Silver Line, which will include five stations including four in Tysons Corner, was in late December of 2013. However, in mid-June, contractors said that their timeline to turn over the line's new stations to WMATA in October instead of September.
That pushed the potential opening of the Silver Line from December to January of 2014. Eight more weeks would likely push the project's opening into at least March.
