Solomons onto the Governor Thomas Johnson Bridge over the Patuxent River. In 1979, the divided highway was extended south from Prince Frederick to Port Republic. MD 2/MD 4 was shifted west to a new divided highway between south of St. Leonard to Port Republic in 1981, with the former two-lane routing designated part of MD 765. In 1987, MD 2/MD 4 between Solomons and south of St. Leonard was shifted to a new divided highway. The bypassed alignment through Lusby and Solomons became another part of MD 765. The Ritchie Highway was originally the main route between Baltimore and Annapolis prior to the completion of I-97 in 1995. Originally, MD 10 was intended to provide a limited-access route between Baltimore and Annapolis, but this route was not completed south of Pasadena after it was deemed that an alternative freeway along the MD 3 corridor (present-day I-97), which required less destruction of residences and businesses, should be built. In 2010, construction took place to improve the intersection of MD 2/MD 4 and MD 231 in Prince Frederick, widening the road to six lanes in the vicinity of the intersection. This project was the first phase of a larger project to expand MD 2/MD 4 to six lanes between MD 765 south of Prince Frederick and Stoakley Road north of Prince Frederick. In 2018, construction began on the second phase of widening between north of the MD 231 intersection and Fox Run Boulevard. The widening of this section was completed on November 23, 2020.

The road was laid out to a width of 160 feet (50 m) from Light Street to Locust Point in the early 1910s, providing better access to the new city-owned piers in preparation for increased trade via the Panama Canal and existing steamship lines to Europe.
