Maryland Route 575 (MD 575) is a state highway in the U.S. state of Maryland. Known as Worcester Highway, the state highway runs 2.7miles from U.S. Route 113 (US 113) in Friendship north to MD 589 and US 113 in Showell. MD 575 is the old alignment of US 113 in northern Worcester County. The state highway was assigned in 2000 when US 113 was relocated as a four-lane divided highway through the area. As part of the overall project to expand US 113 to four lanes from Berlin to the Delaware state line, 14 unsigned auxiliary routes of MD 575 were designated on old alignments or service roads between 2002 and 2004.
MD 575 begins at a right-in/right-out interchange with northbound US 113, also known as Worcester Highway, in Friendship. There is no access to southbound US 113. MD 575 heads northeast as a two-lane undivided road through farmland. The state highway turns north after intersecting MD 452 (Friendship Road) and passing Carey Road. MD 575 passes under MD 90 (Ocean City Expressway) with no access. The state highway receives an off-ramp from northbound US 113 before reaching its northern terminus at MD 589 (Racetrack Road). Access to southbound US 113 is provided by heading west on MD 589, while a ramp to northbound US 113 continues straight.
MD 575 is the old alignment of US 113 between Friendship and Showell. The state highway was originally constructed by 1921 and designated part of US 113 in 1927. This stretch was bypassed in 2000 as part of a larger project to expand US 113 to a four-lane divided highway between the existing northern end of dual highway just north of US 50 in Berlin and the Delaware state line. In 2000, a ramp from westbound MD 90 to MD 575 was closed when MD 90's current partial cloverleaf interchange with US 113 opened. MD 589 and MD 575 were realigned to their present termini in 2001. All portions of US 113's interchange with MD 589 and MD 575 were completed in 2002.
Auxiliary routes of MD 575 were designated between 2002 and 2004 as portions of the project to expand US 113 to a divided highway were completed. These routes are either old alignments of US 113 or service roads to provide access to private property or county highways compromised by the construction of the four-lane divided highway. Fourteen auxiliary routes were established, increasing in alphabetical order geographically from MD 575A in Showell to MD 575N just south of the Delaware state line. MD 575A through MD 575F were assigned in 2002 as the US 113 divided highway reached Jarvis Road (MD 575F). MD 575G through MD 575J and MD 575M were established in 2003 when the divided highway was completed to the state line. MD 575K, MD 575L, and MD 575N were designated in 2004 to bring the overall project to a close.
