The West Baltimore tunnel represents the largest investment in the announcement. It is followed by roughly $2 billion to help Amtrak replace the Susquehanna River Rail Bridge, which runs parallel to Interstate 95 and connects Havre de Grace and Perryville in the northeast part of the state. The project will replace a more than 100-year-old bridge, improving safety, trip time and capacity, in addition to making navigation channels easier for boats.
