Double-stacking

In a move Maryland Gov. Larry Hogan called “an absolute game-changer” for East Coast freight transportation, officials broke ground on Nov. 29 on a $466 million expansion of the 126-year-old Howard Street Tunnel underneath Baltimore. The move, expected to be a boost for rail and intermodal traffic because it will finally allow double-stacking of containers through the Port of Baltimore, will move an estimated 160,000 more containers a year when the project is completed in two years.
