Please be aware that third-party contractors will be carrying out a Geooptic Survey of Islington Tunnel to support planned future construction works above the tunnel.
To minimise disruption to navigation, the survey will be undertaken overnight using a barge within the tunnel. These overnight working arrangements have been put in place to avoid impacting boats passing through the tunnel during normal operating hours.
Should passage through the tunnel be required during the overnight works, the contractor will temporarily move the working barge to allow safe and unobstructed transit through the tunnel.
We appreciate your patience and understanding while these important survey works are completed.
