The Fort McHenry Tunnel is a four-tube, bi-directional tunnel that carries traffic on Interstate 95 (I-95) underneath the Baltimore Harbor. Named for nearby Fort McHenry, the tunnel is the lowest point in the Interstate Highway System under water.[2]
Construction began in May 1980; the tunnel opened on November 23, 1985. Having consumed some $750 million (equivalent to $2.1 billion in 2023), it was the most expensive Interstate project until surpassed by the Big Dig in Boston.[3] As of 2009[update], it was used by 43.4 million vehicles annually.[needs update]
Tolls are collected in both directions. The toll for cars is $3 with a Maryland E-ZPass and $4 with another state's E-ZPass. Vehicles without an E-ZPass pay more, as do those with more than two axles—up to $45 for a 6+ axle vehicle without an E-ZPass.[4] All-electronic tolling using E-ZPass or toll-by-plate started in March 2020 as a result of the COVID-19 pandemic and was made permanent in August 2020.[5] A project to demolish the toll plaza and replace it with overhead gantries for open road tolling started in 2022.[6]
