Blackwall Tunnel Northbound Refurbishment

Contract Value £30m
This single bore 1364 metre tunnel carries the A102 beneath the river Thames and is a key link between north and south sides of the river.

The tunnel, along with all four of the associated ventilation shafts are being upgraded as part of the project for which VVB are providing a full M&E installation package to BAM Nuttall. This includes all enabling, temporary and permanent M&E works.

Both of which have to progress whilst maintaining the functionality of the tunnel requiring VVB to offer temporary solutions to ensure the tunnel remains safely operational for the duration of the project.
