(Updated at 5:55 p.m.) The combined cost of the Columbia Pike and Crystal City streetcar systems is now estimated at $585 million.
Presenting an overview of her proposed FY 2015-2024 Capital Improvement Plan to the Arlington County Board this afternoon, County Manager Barbara Donnellan and her staff said that the cost of the streetcar systems had risen $190 million from the 2013 CIP due to changes in the size of the streetcar vehicles, higher engineering and start-up costs, higher inflation and a larger project contingency.
