William Preston Lane Jr. Memorial (Bay) Bridge In May 2020, the Maryland Transportation Authority (MDTA) began collecting tolls via highway-speed all-electronic tolling (AET) at the Bay Bridge (US 50/301). With cashless toll collection, there’s no slowing or stopping to pay tolls. Instead, motorists pay tolls at highway speed via E-ZPass, Pay-By-Plate or Video Tolling. Benefits include increased safety, less engine idling and better fuel efficiency.
