Connecting the North and South Coasts of the Finnish Gulf with the Kotlin island, the 24.5 km long Barrier provides flood defence to the residents and businesses of low-lying St. Petersburg.  We will visit the impressive structure which comprises eleven rock and earth embankment dams, six water discharge sluices to accommodate outflow from the river Neva and two navigation channels equipped with closing gates, road bridges and a road tunnel.

Our host on-site will be Pieter van Vuuren of Boskalis, Project Director of the currently ongoing A2 Contract. This contract includes dredging for soil improvement, supply and placing of sand for sand and rock to close last part of the dam and the construction of the southern part of the tunnel under the shipping channel.  We will also hear about works completed in the past two years such as dredging the new access channel.
