context_page_description: Maryland Route 43 is a state highway in the U.S. state of Maryland. Known as White Marsh Boulevard, the state highway runs 8.65 miles from Interstate 695 near Parkville east to MD 150 in Middle River. MD 43 is a four-lane divided highway in eastern Baltimore County that connects the northern and eastern suburbs of Baltimore with the commercial center of White Marsh, where the highway has junctions with I-95 and U.S. Route 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.
context_section_description: White Marsh Boulevard was constructed concurrent with the portion of I-95 between the boulevard and I-695 in 1962 and 1963.  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.  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.
  Construction on the western extension of MD 43 from White Marsh Town Center west to I-695 began in 1989 with construction of bridges.  The roadways, including the interchange ramps at US 1, were under construction by 1991.  MD 43 was rebuilt at Honeygo Boulevard and completed west to I-695 in January 1993.  Around 1997, the pair of ramps at MD 7 were added.  Work on the eastern extension of MD 43 from US 40 east to Middle River began with bridge work in 2004.  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.
