History
What is now I-370 was originally proposed as part of the Intercounty Connector in the late 1970s. The I-370 freeway opened on December 17, 1988, connecting I-270 to the Shady Grove station.
In 2007, construction began on MD 200, which was to head east from I-370. At this time, the ramp from Shady Grove Road to westbound I-370 was shifted to a new alignment.[8] In 2009, the lanes along I-370 were shifted to allow for construction of the MD 200 interchange.[9] Construction on this segment of MD 200 was completed in February 2011, with the road opening to traffic on February 23.[10][11] As a result of the completion of MD 200, the eastern terminus of I-370 was truncated to the west end of MD 200, with the freeway connection to the Shady Grove station becoming MD 200A.[12]
