MD 170 is a part of the National Highway System from its southern terminus in Odenton to I-695 in Linthicum. Within that stretch, there are two sections that serve as intermodal passenger transport links: from its southern terminus to MD 32 in Odenton, and from MD 176 to MD 162 along the perimeter of BWI Airport. The portions from MD 32 in Odenton to MD 176 in Severn and from MD 162 to I-695 within Linthicum are National Highway System principal arterials.[1][3]
History
When the
Construction on the highway from Severn to Linthicum became a high priority with the United States' entrance into World War I; the remainder of the Severn–Linthicum highway and the highway from the railroad at Severn southwest to newly established Camp Meade, now collectively called the Camp Meade Road, were paved in 14-to-16-foot-wide (4.3 to 4.9 m) concrete between 1916 and 1919. Belle Grove Road from Pumphrey to Brooklyn Park was also paved in concrete in this period of time.[4][9][10] A poorly constructed portion of the Camp Meade Road between Wellham Crossroads and Dorsey Road was repaved with asphalt in 1919.[9] MD 170 was relocated at the railroad crossing when the highway's overpass of the Pennsylvania Railroad was completed in 1931.[11][12] The old road, which is now Severn Station Road west of the tracks and Old Camp Meade Road to the east, became MD 483.[5]
Telegraph Road from Severn to Odenton was built as a concrete road in three sections. The highway was constructed from the right-angle turn in the Camp Meade Road in Severn south to Evergreen Road in 1932 and 1933.
MD 170 was relocated as a 24-foot-wide (7.3 m) road from MD 176 north to what is now the MD 170–MD 162 junction in 1947 and 1948 to make way for the construction of Friendship International Airport.
When the expressway spur between MD 168 and U.S. Route 301 (now MD 648) was built between 1951 and 1954, the expressway, which became part of the Baltimore Beltway, included an at-grade intersection with MD 170 between Linthicum and Pumphrey.[20][28] This junction was replaced with the present interchange in 1967; MD 170 was expanded to a divided highway on either side of the interchange in 1968.[29][30][31] MD 170's grade separation with Stoney Run Road on the west side of the airport was built in 1982.[32][33] The state highway was expanded to a four-lane divided highway from north of I-195 to MD 162 when the adjacent east–west portion of MD 162 was built in 1988.[34][35] MD 170 was expanded to a four-lane divided highway through its interchange with MD 100 when the single-point urban interchange was built in 1995.[36][37] MD 170 had been expanded to four lanes through its interchange with MD 32 and from MD 176 through the I-195 interchange, and had its southern terminus rolled back from MD 677 to MD 175, by 1999.[38]
