Crown Bridges, Helsinki
We are building a railway project, where the level crossing of train traffic is being converted into an underpass to improve traffic safety and for the upcoming electrical engineering of this section of the railway.
In short, we will dig an excavation for the underpass, then build the bridge, complete the train connection and let trains run along the bridge. We will simultaneously complete the work related to safety devices on the track. The work also includes street arrangements and work such as the road running under the bridge and linking it to existing roads. We will also move clean water and sewage pipes underneath the new road. Finally, we will landscape the old connection. The construction work also includes the construction of a passing loop for the duration of the work in order to ensure smooth train traffic.
As part of the same project, we also built an underpass which meets the height requirements of special transport routes under a nearby bridge so that special transport can pass through the area even after the level connection has been removed. In addition, the work also includes a supporting wall to separate the pedestrian and bicycle route from the road and adding lighting on the new street.
“There’s a school in the area, so schoolchildren will no longer have to cross the train tracks. The safety of other traffic will also improve at the same time. Our customer, the Finnish Transport Infrastructure Agency, intends to remove many level crossings in Finland in order to avoid unfortunate level-crossing accidents in the future,” says Production Manager Markus Malmivuori from YIT.
