Invitation to tender, deadline 14th March, 2006 for completion of navigation opening C1 and tunnel in St Petersburg. The tunnel is for a 2 x 3-lane highway i.e. a total of six traffic lanes. The site is about 15 km to the west of St Petersburg as part of the 24.5 km-long flood protection barrier being constructed for the city. It is a 1.2 km structure, to be built with reinforced concrete boxes in the dry at the site of a future navigation channel. Construction commenced seven years ago but was stopped. About 60% of these boxes are already built, the remaining ones and all the joints have to be done. The existing boxes have to be rehabilitated. The channel will then be flooded once the tunnel is finished. Halcrow is designer and Royal Haskoning of the Netherlands is the project manager. Click here to know more about the project.
