H Street was separated in two with the railway track where it intersected with Delaware Avenue when Union Station started to be built in 1907. This split created distinct neighborhoods east and west of the railway which have grown independently. In 1902, it was originally planned that H street NE would be cut for at Delaware Avenue. Thanks to involvement of the Northeast Washington Citizens' Association, the plan was changed to having a tunnel built to retain the connection between the two sides of the track.
