For the Crusellinsilta bridge, the contract includes the replacement of the bridge surface structures and the waterproofing of the deck, as well as the partial renovation of the bridge support tower, or pylon. In addition, cracks in the structures are will be injected and corrosion damage repaired to the necessary extent. The street area at the northern and southern end of the bridge will undergo surface structure and stormwater drain modifications.

Surface structures, waterproofing, edge beams and railings will be replaced on the Lapinlahti overpass. The underside of the bridge deck will be coated throughout and the undersides of the front walls spiked and patched by casting. The Baana route passing under the bridge will be provided with a separate protective structure to protect pedestrian and bicycle traffic.

Bridge contract will affect traffic

Tram traffic on Crusellinsilta bridge will be interrupted for the period from 3 June to 1 September and replaced by buses. Both the bridges will be available for vehicle, pedestrian and bicycle traffic, though the work area will narrow the lanes and pedestrians and cyclists can only use one side of the bridge. The contractor will guide traffic with signs. Traffic arrangements are estimated to change 2–3 times during the contract, and these will be communicated separately closer to the change dates.

The bridge contract is scheduled to be completed at the end of November. The contractor is Kreate Oy.
