Therefore, the completion of the former two Shinkansen lines was delayed by five years from the plan, and the work to construct the Narita Shinkansen line was stopped (however, the facilities constructed for this Shinkansen line were used later when JR East and Keisei Electric Railway Co., Ltd. built a railway line to access Narita airport).
このため、前者2つの新幹線は予定より工事が5年も遅れ、成田新幹線に至っては工事中止となってしまった（ただし、後に東日本旅客鉄道と京成電鉄の成田空港乗り入れの際にこの新幹線建設で作られた設備が生かされることになる）。
