The summary is made by artificial intelligence and checked by a human.
Hakaniemi’s tram service will be cut off for 10 months starting in March 2025.
During that time, trolleys will not be able to travel along Pitkääsilta at all.
HSL plans temporary terminuses and detours for tram lines.
In the Siltasaarenkatu project, the most time-consuming are pipe relocations and the construction of new pipe routes.
Just when people have started to get used to the second phase of Mannerheimintie’s renovation, a new big street project is looming in Hakaniemi.
The tram service on Siltasaarenkatu will be completely cut off due to the switch contract for 10 months from next March.
This means detours for dozens of lines of both tram and bus traffic heading east.
Helsinki Region Transport (HSL) can generally direct bus traffic via Pitkänsilla, although a detour via the new Hakaniemensilla and Siltavuorenranta may be used some of the time.
For trams, Pitkäsilta is a real umbilical cord and lines 3, 6, 7 and 9 do not go beyond Hakaniemi. Correspondingly, the passage of these tram lines from the center to the north will stop at Pitkänsilta.
In the construction contract, a new switch will be made to connect Laajasalo’s new tramway to the Siltasaarenkatu tram lines.
in HSL traffic planners have already outlined the solution for the northern end of the tram lines. The old tram rails on the Second line give the opportunity to recycle tram traffic to the old terminus of the First line.
Passengers can continue their journey south from Hakaniemi by metro or bus.
HSL’s project manager Teuvo Syrjälän According to this, a new temporary switch connection will be made to Hakaniemi, which will give the trams the opportunity to turn from Hämeentie to the Second line.
The trolleys of all four trolley lines running to Hakaniemi cannot fit in the temporary terminus. The terminus of the first line would serve at least lines 6 and 7. Line 3 would probably be diverted to Helsinginkatu. The plans are still being refined.
“Previously, there was a tramway connection around the Arena block, which was used to turn around in Hakaniemi from the south. This connection was removed during the renovation of Hämeentie”, says Syrjälä.
Long bridge the south side does not have the same opportunities for a temporary turning run as in Hakaniemi.
According to Syrjälä, an alternative could be to recirculate the roads via Kruununhaa back to the south.
The traffic planners will finalize the detours during the fall. HSL will provide more detailed information about traffic and the route closer to the start of the exceptional arrangement.
Individually under normal conditions, the construction of the switch would not take 10 months, nor would the project manager of Kruunusilto Marko Jäntti let’s justify the traffic stop with tram transport only.
In the Siltasaarenkatu contract, the most time is spent on pipe transfers and the construction of new pipe routes. Due to the proximity of the houses and the metro line, the rock cannot be mined by blasting.
“We have to make new pipe channels by wedging. It’s slow,” Jäntti characterizes.
New the construction of the tram switch makes it possible to continue the Laajasalo tramway from the temporary terminus in Hakaniemi towards the center and the West Terminal in Jätkäsaari. This continuation could be realized at the turn of the decade.
Passenger traffic from Laajasalo to Hakaniemi will start in 2027.
The Siltasaarenkatu part of the crown bridges’ overall project has continuously produced new twists and turns during the fall. Initially changes in lane arrangements caused congestion in August, eastbound bus traffic at the northern end of Pitkänsilla.
When this traffic jam had been cleared, underground was found concrete mystery cottage. After guessing, it turned out to be the exit from the population shelter of Elanto’s house.
According to preliminary estimates, the renovation of Mannerheimintie is scheduled to continue until next autumn 2025.
