'''Maryland Route 43''' ('''MD 43''') is a [[state highway]] in the U.S. state of [[Maryland]].  Known as '''White Marsh Boulevard''', the state highway runs {{convert|8.65|mi|km}} from [[Interstate 695 (Maryland)|Interstate 695]] (I-695) near [[Parkville, Maryland|Parkville]] east to [[Maryland Route 150|MD 150]] in [[Middle River, Maryland|Middle River]].  MD 43 is a four-lane [[divided highway]] in eastern [[Baltimore County, Maryland|Baltimore County]] that connects the northern and eastern suburbs of [[Baltimore, Maryland|Baltimore]] with the commercial center of [[White Marsh, Maryland|White Marsh]], where the highway has junctions with [[Interstate 95 in Maryland|I-95]] and [[U.S. Route 40 in Maryland|U.S. Route 40]] (US 40).  The state highway was built from west of I-95 to US 40 concurrent with the construction of I-95 in the early 1960s.  MD 43 was extended west to Parkville in the early 1990s and east to Middle River in 2006.

MD 43 begins at a partial interchange with I-695 (Baltimore Beltway) near Parkville that includes ramps from eastbound I-695 to eastbound MD 43 and from westbound MD 43 to westbound I-695.  The state highway heads east as a four-lane divided [[limited-access highway]] through the forested valley of Whitemarsh Run.  As MD 43 passes through the community of [[Fullerton, Maryland|Fullerton]], the highway has intersections with county-maintained Walther Boulevard and a pair of two-way [[quadrant interchange|quadrant ramps]] that connect the boulevard with either direction of [[U.S. Route 1 in Maryland|US 1]] (Belair Road), under which MD 43 passes between the pair of ramps.  The state highway continues east into the planned community of White Marsh where the highway has intersections with Perry Hall Boulevard and Honeygo Boulevard, which serve [[White Marsh Town Center]] and its centerpiece, [[White Marsh Mall]].<ref name="Maryland HLR"/><ref name="Google Maps MD 43"/>

East of the town center, MD 43 veers away from Whitemarsh Run and meets I-95 (John F. Kennedy Memorial Highway) at an interchange; this interchange has full access to I-95 along with access to the southbound direction of the I-95 Express Lanes and from the northbound direction of the I-95 Express Lanes. Past I-95, the route has a partial interchange with [[Maryland Route 7|MD 7]] (Philadelphia Road).  The state highway continues east over [[CSX Transportation|CSX]]'s [[Philadelphia Subdivision]] railroad line and US 40 (Pulaski Highway).  The US 40 interchange includes a two-way quadrant ramp between the two highways and a direct ramp from southbound US 40 to westbound MD 43.  East of US 40, the state highway crosses over Whitemarsh Run, which heads north to its mouth at the tidal Bird River, itself a tributary of the [[Gunpowder River]].  MD 43 curves southeast through a forested area with scattered industrial parks, where the highway crosses over Bird River Road and Windlass Run and intersects Crossroads Circle.  The state highway continues southwest into Middle River, crossing over [[Amtrak]]'s [[Northeast Corridor]] railroad line before reaching its eastern terminus at MD 150 (Eastern Boulevard) just east of the [[Martin State Airport station]] on [[MARC Train|MARC]]'s [[Penn Line]] and [[Martin State Airport]].<ref name="Maryland HLR"/><ref name="Google Maps MD 43"/>

MD 43 is a part of the [[National Highway System (United States)|National Highway System]] as a principal arterial for its entire length.<ref name="Maryland HLR"/><ref name="National Highway System"/>

==History==
[[File:MD 43 Korean War Highway sign, May 2023.jpg|thumb|right|Sign noting the designation of MD 43 as the Korean War and Korea Service Veterans Memorial Highway]]
White Marsh Boulevard was constructed concurrent with the portion of I-95 between the boulevard and I-695 in 1962 and 1963.<ref name="1962 map"/><ref name="1963 map"/>  The state highway, which was marked as MD 43 by 1965, originally consisted of a four-lane divided section from the Honeygo Boulevard intersection east to US 40, under which the highway passed then followed the present two-way ramp to an intersection with the U.S. Highway.  The original highway also had its modern [[cloverleaf interchange]] with I-95 and an underpass of MD 7 with no access.  At its western end, MD 43 turned north as a two-lane road along what is now Honeygo Boulevard to its western terminus at Silver Spring Road.<ref name="1965 map"/><ref name="1978 map"/>  Around 1983, in conjunction with the construction of White Marsh Town Center, the state highway's western terminus was moved to just east of the Honeygo Boulevard intersection, which became a three-way directional intersection with an overpass for traffic from westbound MD 43 south onto Honeygo Boulevard toward White Marsh Mall.<ref name="1983 map"/>

Construction on the western extension of MD 43 from White Marsh Town Center west to I-695 began in 1989 with construction of bridges.<ref name="NBI I-695"/>  The roadways, including the interchange ramps at US 1, were under construction by 1991.<ref name="1991 map"/>  MD 43 was rebuilt at Honeygo Boulevard and completed west to I-695 in January 1993.<ref name="1993 map"/><ref name="Transportation Milestones"/>  Around 1997, the pair of ramps at MD 7 were added.<ref name="1997 map"/>  Work on the eastern extension of MD 43 from US 40 east to Middle River began with bridge work in 2004.<ref name="NBI Whitemarsh Run"/>  The state highway was completed east to MD 150 on October 23, 2006, opening up a large area of eastern Baltimore County to commercial and industrial development.<ref name="Maryland HLR 2006"/><ref name="Route 43 Extension Opens"/>

In 2001, the entire highway was dedicated as the '''[[Korean War]] Veterans Memorial Highway''' with signage added in 2007 formally naming it the '''Korean War and Korea Service Veterans Memorial Highway'''.<ref>{{cite web |title=§8-651.
