High volumes of beach traffic as a result of the Chesapeake Bay Bridge made further upgrades to the route necessary. A very straight alignment south through Talbot County was built, the former alignment becoming MD 662. In Salisbury, US 50 was moved from Main Street to Church Street. In Worcester County, its present-day alignment was built, though only dualized east of US 113 in Berlin. Following this, in the mid-1960s, the present four-lane section of US 50 was completed between Salisbury at then-US 13 and Berlin at US 113, its old alignment east of East Main Street becoming MD 346, and Church Street was returned to the city. The rest of US 50 on the Eastern Shore was in the process of being dualized at this time. This included the adjacent span of the Chesapeake Bay Bridge built in 1973, widening the thoroughfare to an asymmetrical five lanes.
