MWAA: Silver Line costs increase due to design modification
The Metropolitan Washington Airports Authority (MWAA) says that design modifications made to enhance the safety and reliability of the Metrorail Silver Line, along with remaining work to finalize Phase 1 of the overall project, will add $76 million, or about 2.6 percent, to the previously announced Phase 1 cost. The new Phase 1 cost remains within the original federally approved Phase 1 budget.
