Bay Crossing Study

Tier 2 NEPA


The Chesapeake Bay Crossing Study: Tier 2 NEPA (Tier 2 Study) is a National Environmental Policy Act (NEPA) study that will analyze alternatives to provide congestion relief and improve travel reliability, mobility and safety across the Chesapeake Bay. The Tier 2 Study is focusing on the Selected Corridor Alternative (Corridor 7) that was identified at the conclusion of the Tier 1 Study. Alternatives will include a No Build Alternative and a range of build alternatives involving various alignments, crossing types and modal and operational alternatives (e.g. transit, pedestrian, bicycle, etc.). Corridor 7 is two miles wide and runs 22 miles from the Severn River Bridge in Anne Arundel County to the U.S. 50/U.S. 301 split in Queen Anne’s County.
