VermonrinneStreets and trafficLeppävaara
A need for change has been discovered in the 19 May 2016 Vermonrinne street plan.
During the 2017 construction planning phase following the street planning phase, the plan was found to be incompatible with an existing gas pipeline owned by Gasum. This existing gas pipeline is located in the street area between the turnaround at the western end of Vermonrinne and the Vermonpolku junction. In the aforementioned street area, new street surface structures cannot be built on top of the existing gas pipeline without first building a protective slab structure on top of the pipeline. Construction of a protective slab was found difficult due to the problematic position of the gas pipeline. The construction of a protective slab would require turning some residential courtyard areas into a construction site. Therefore, the cross-section of the street will be changed so as not to extend the new street surface structures over the gas pipeline.
The width of the Vermonrinne roadway is currently 5.0 m. During the construction of the Jokeri Light Rail in 2019, a temporary 2.0-metre wide pavement was built between the turnaround at the western end of Vermonrinne and the Vermonrinteenkuja junction. Due to the gas pipeline arrangements, the street area between the turnaround at the western end of Vermonrinne and the Vermonpolku junction is presented as a living street with a width of 5.0–6.0 m. A narrow roadway would allow sufficient space for the gas pipeline along the northern edge of the street area. A living street is a street where the speed of vehicles should not exceed 20 km/h and where pedestrians are allowed to use all parts of the street as long as they do not unnecessarily obstruct vehicle traffic. Vehicles moving on a living street must always give way to pedestrians and only park in the designated parking spaces. The planned living street driveway has been narrowed at the eastern end of the living street section to further reduce the driving speeds in the area.
The street plan has also been updated with the on-street parking spaces determined in the 2017 construction design phase.
