 In the 1960s, the route was rerouted along US 50 to the Eastern Shore where it split from US 50 and was routed from there up former Maryland Route 71 into Delaware.Today, Route 301 is a multi-lane highway throughout its path through the state with the exception of the Governor Harry W. Nice Memorial Bridge; the nine miles (14 km) of MD 3 between US 50 and Interstate 97 is also a four- and six-lane divided highway and is part of the same continuous physical route.The segment of the highway between the eastern end of the Chesapeake Bay Bridge and the US 50/US 301 split in Queenstown was originally built as a four-lane at-grade divided expressway.
