However, no detailed studies into the feasibility or impact of this route were undertaken at the time. A later study conducted in 1964 included diagrams of the 1959 route, but with the roadway in a 4-2-4 configuration instead of a 3-3 configuration. 1962 North Central Freeway In November 1962, the Kennedy administration released a document "Recommendations for Transportation in the National Capital Region; A Report to the President for transmittal to Congress by the National Capital Transportation Agency". It replaced the 1959 concept of 3 separate northern radial mixed traffic highways with that of a 2 into 1 "Y" route for a North Central Freeway as inside-the-Beltway I-70S, joined by an I-95 North East Freeway near Fort Totten, and continue together as the I-95 North Central Freeway. The I-70S and I-95 portions of the North Central would be routed along the existing B&O Metropolitan Branch RR (today's WMATA Red Line). Accordingly, this avoids "the substantial relocation of persons, loss of taxable property and disruption of neighborhoods that would result from construction of the Northeast, North Central and Northwest Freeways proposed in the 1959 plan. Further savings are realized by placing the rapid transit lines to Silver Spring and Queen's Chapel in this same railroad corridor." This B&O "Y" route concept North Central Freeway was later politically undermined by planning that failed to follow it. 1963-64 North Central Freeway Study In a series of proposals published in 1963 and 1964, the subsequent study of the North Central Freeway and Northeast Freeway indirectly ignored earlier suggestions regarding the use of the B&O railroad corridor; instead, no fewer than 17 separate alignments were proposed for the NCF south of the Northeast Freeway, and a staggering 35 were proposed for the NCF (I-70S) north of it, many of which did not make much use of the railroad alignment. One important aspect of the study was the consideration of consolidating the North Central Freeway (I-70S) and Northeast Freeway (I-95) into a single freeway that would run south to the Inner Loop (designated solely as I-95). Many different alignments, including ones paralleling Georgia Avenue and Sherman Avenue through northern D.C., were considered as part of a consolidated routing of the North Central Freeway south of the Northeast Freeway. The study as a whole generally rejected alignments paralleling Georgia Avenue in favor of alignments along the B&O railroad, primarily due to the residential nature of the former
