Paloheinä Public Transportation Tunnel

HKR-Rakennuttaja

The Paloheinä tunnel is a traffic tunnel running underneath Helsinki Central Park for more than a kilometer. Rather than a new bus line passing through the park, it was decided to run it through a tunnel under the park and preserve the recreational uses on the surface. Currently, the tunnel is only used by public bus transportion, but the design has also accounted for possible future tram traffic.
