How much did Washington Metro cost to build?
The Washington Metro is the Washington, D.C. rapid transit system whose original plan was finally completed in 2001 as a 103-mile system. Brian Potter's Construction Physics essay of 26 September 2023 says it cost 10 billion dollars in nominal dollars and closer to 20 billion if all expenditures were adjusted to 2001 dollars, after a 1968 projection of 1.8 billion dollars in 1968 money and an estimate of 6.8 billion by 1978.
