The Chesapeake Bay Crossing Study: Tier 1 NEPA (Bay Crossing Study) is a National Environmental Policy Act (NEPA) study that will result in the identification of a preferred corridor alternative to address congestion at the Chesapeake Bay Bridge and evaluation of its financial feasibility.

The Bay Crossing Study includes scoping; purpose and need development; corridor alternative analysis and screening; traffic and environmental analyses; and public and agency involvement. The study is expected to be completed in December 2020.

The Maryland Transportation Authority (MDTA) owns, finances, operates, and maintains the William Preston Lane, Jr. Memorial (Bay) Bridge and is conducting the $5 million Bay Crossing Study.
