was resurfaced with bituminous concrete in 1969. MD 20E was an unnamed spur from MD 20C to a dead end near MD 20C's northern end near Cove Road. The portion of MD 20D from near Fort Howard to Sparrows Point Road in Edgemere, then MD 718, was transferred from state to county maintenance through a December 12, 1985, road transfer agreement. The remainder of MD 20D and all of MD 20A, MD 20B, MD 20C, and MD 20E were transferred to Baltimore County control through an October 1, 1998, road transfer agreement. One segment of MD 20 was constructed later and was not part of North Point Road. MD 20F was an unnamed connector from southbound MD 151 to MD 20D. The highway began as a loop ramp from southbound MD 151, crossed east over both directions of MD 151, and ended at MD 20D. What became MD 20F was constructed as one of several ramps built to connect MD 151 and MD 20 with the new Bethlehem Boulevard in 1957 and 1958. However, the road did not receive the MD 20F designation until 1976. MD 20F was replaced by an eastward extension of newly designated MD 158 (Bethlehem Boulevard) when Bethlehem Boulevard was transferred from Bethlehem Steel control to state maintenance through an October 17, 1989, road transfer agreement. Former MD 20F was destroyed by the reconstruction of I-695 and its junction with MD 151 and MD 158 completed in 1999. MD 27 Maryland Route 27 was the designation for what became the original alignment of US 29 in Montgomery and Howard counties when the U.S. Highway was extended into Maryland in 1934. MD 27 roughly followed modern US 29 from the District of Columbia to White Oak, MD 650 from White Oak to Ashton, MD 108 from Ashton to the original village of Columbia, US 29 again and then Old Columbia Pike into Ellicott City. After US 29 was extended into Maryland, MD 27 was placed on most of its modern course from Germantown to Westminster, which had previously been MD 29. MD 29 Maryland Route 29 was the original designation for modern MD 27 from US 240 (now MD 355) in Germantown north to US 140 (now Main Street) in Westminster in Montgomery County, Howard, Frederick, and Carroll counties. MD 29 was redesignated MD 27 after US 29 entered Maryland in 1934, replacing the original MD 27
