President Biden plans to replace the Baltimore and Potomac Tunnel, a rail connection between Philadelphia and Washington, as part of his $1 trillion bipartisan infrastructure legislation, reports WBAL. The current tunnel has one track, causing trains to slow down and increasing the risk of collapse. The new tunnel, named for Frederick Douglass, will have two tracks and allow for faster travel. The project, which includes related bridges and equipment upgrades, could cost $6 billion, with Maryland committing $450 million and the federal government providing up to $4.7 billion. Biden plans to announce labor agreements for the tunnel's completion and to ensure good wages for workers. The trip to Baltimore is one of two infrastructure-focused trips this week, with the second being a visit to New York to discuss a new rail tunnel under the Hudson River.
