The Washington Post reports, the Silver Line extension of the Washington Metro rail system is scheduled to open next Tuesday, November 15. “While four years behind schedule, the $3 billion project will bring the first rail connections between the Washington region’s largest economic powerhouses — downtown D.C. and Tysons — the area’s international airport and the nation’s wealthiest county.” The Metropolitan Washington Airports Authority (MWAA) managed the problem-plagued construction of the line, which started in 2014. It funded nearly half its project budget — and $200 million in cost overruns — with toll revenue from the Dulles Toll Road, one of its assets. MWAA transferred control of the line to Metro in June.
