RAILWAY-CROSSING AT JESSHEIM / PIR II OSLO AS
Pir II Oslo AS has won the competition to design a new railway-crossing in the heart of Jessheim, a town of 20000 inhabitants located close to Oslo Airport Gardermoen. Five teams were competing, and the task included both a bridge-project and an underpass.
Heavy population growth creates a need for a closer connection between the eastern and western parts of Jessheim. The railway-crossing will connect the urban developments on both sides, and contribute to the creation of a coherent central area.
In addition to improving the connection between different areas of the town the crossing must also optimize the flow of people at the new train-station.
Underpass:
The design originates from the idea of placing both public functions and green areas on the level of the underground passing, in order to make it an integrated part of the townscape. Openness, light and variation have been important goals during the creation of the project.
The underpass relates to the local conditions in the north and in the south in very different ways.
To the north a linear, active and flexible wall is created. The wall contains a number of different functions (such as elevators, kiosk, ticket booth, bicycle repair, mini art gallery), and is intended to be integrated with future urban developments north of the site. The wall is designed to have an open and inviting visual impression, and it activates and lights up the dark areas underneath the railway tracks.
To the south the connection up to the existing street level is shaped like a terraced and organically shaped park, connecting with existing green areas and public space. On this side the footprint of the underpass area is determined by local conditions, such as adjustments to existing listed buildings. The surfaces on the south side of the underpass are shifting between hard and soft/green in order to adjust to different functions/conditions from the west to the east.
Bridge:
The bridge is adjusting to the public spaces on each side of the railroad tracks by landing in the north on the west side and in the south on the east side. This displacement has made it possible to create a visual connection underneath the bridge, and a distinct architectural expression. The bridge is designed to look both light and structural at the same time. The goal has been to create a striking element that marks both the town- and station-connection in a distinct manner.
The bridge lands immediately on both sides of the railroad tracks to allow for direct connections to all areas on the western and eastern part of town, and the shortest possible distance between platforms.
The construction can be pre-fabricated in elements and lifted in place in order to affect train traffic as little as possible.
The jury of the competition have come to the conclusion that Pir II Oslo AS has found the best solution for both bridge and underpass.
