Maryland Roads


The Maryland highway system consists of roads in the US state of Maryland that are maintained by the Maryland State Highway Administration (SHA). The three main systems of roads that comprise the Maryland highway system are Interstate Highways, US Highways, and Maryland state highways. Other roads in Maryland are maintained by individual cities and counties.

Interstate Highways and US Highways are assigned at the national level. Interstate Highways are numbered in a grid—even-numbered routes are east–west routes (the lowest numbers are along Mexico and the Gulf of Mexico), and odd-numbered routes are north–south routes (with the lowest numbers along the Pacific Ocean). US Highways are also numbered in a grid—even numbered for east–west routes (with the lowest numbers along Canada) and odd numbered for north–south routes (with the lowest numbers along the Atlantic Ocean). For this reason, mainline (two-digit) Interstate Highways in Maryland all have numbers between 81 and 97 for north-south routes and between 68 and 70 for east-west routes. In addition, mainline US Highways all have numbers between 1 and 29 for north-south routes and between 40 and 50 for east-west routes. Three-digit Interstate and U.S. Highways, also known as "child routes," are branches off their main one- or two-digit "parents". The Interstate and US Highways are generally maintained by the SHA, with some toll roads maintained by the Maryland Transportation Authority (MdTA) and some roads maintained by municipalities, including most roads in the city of Baltimore. Interstate 95 (I-95) and U.S. Route 40 (US 40) are the longest examples in the state.

Maryland state highways are the other state highways maintained by the SHA. Some state highways are maintained by municipalities while the Maryland Route 200 (MD 200) toll road is maintained by the MdTA. All roads maintained by the SHA are assigned route numbers, ranging from through routes passing through multiple counties to minor service roads that are less than a mile long. Many of the shorter state highways are unsigned. Some routes consists of multiple segments with letter suffixes; these suffixes are unsigned with the exception of MD 835A. There are two geographical clusters for Maryland state highways. The first, ranging from 2 to 37, consists of longer intercounty routes, with 2 to 6 in Southern Maryland, 7 to 10 originally skipped, 12 to 21 on the Eastern Shore, and 22 to 37 running west from Central Maryland to Western Maryland. The second cluster consists of routes from 38 to 378, running across the state from Garrett County in the west to Worcester County in the east. Numbers above 378 are assigned randomly.

MD 346 westbound past US 113 in Berlin

Maryland Route 346 (MD 346) is a state highway in the U.S. state of Maryland. The state highway runs 23.72 miles (38.17 km) from U.S. Route 50 Business (US 50 Business) in Salisbury east to US 50 in Berlin. MD 346 is the old alignment of US 50 between Salisbury and Berlin, connecting those cities with Parsonsburg, Pittsville, and Willards in eastern Wicomico County and Whaleyville in northern Worcester County. Much of what is now MD 346 was built as the original state road between Salisbury and Ocean City in the mid-1910s. The highway was designated US 213 in 1927 and changed to US 50 in 1949. MD 346 was first applied to Church Street in Salisbury in the 1940s; this designation was removed in 1954. MD 346 was reassigned in the mid-1960s to the old alignments of US 50 left behind after US 50's bypass of Berlin opened in the late 1950s and the US 50 divided highway was completed between Salisbury and Berlin in the mid-1960s.
