On April 15, JR East announced a plan to avoid the stone piles of the Takanawa embankment within the planned area of the Haneda Airport Access Line (tentative), which is under construction.
The Takanawa Chikkebi was an embankment built along the coast at that time for the construction of the railroad in the early Meiji period, and part of the stone wall was discovered in conjunction with the Shinagawa Station improvement work (April 2019). On the Haneda Airport Access Line, part of the stone masonry was found during the trial excavation from July 2022 to June 2023, and has been identified as Takanawa Chikkemi after the investigation.
The company has now decided to “preserve a portion of the Takanawa embankment that is assumed to exist under the Tokaido Line tracks in its current state” by shifting the starting point of the Haneda Airport Access Line’s downward grade approximately 100 m closer to Shinagawa than originally planned.
As a result of literature and field research, there is a possibility that the abutment of the fifth bridge at the time of the railroad’s opening may remain in the abutment of the Zogyoba viaduct, and the possibility that the area near Tamachi Station is on the Satsuma-daiba of the late Edo period, etc., it was decided to preserve records, including the Takanawa Chikkyo.
