All are built to last, with thick concrete hulls accessed by the heaviest steel doors we've ever opened. How the barrier was installed The barrier was built over a 520m wide stretch of the Thames near Woolwich in south London. At full closure, the river can be up to four metres higher on one side of the Barrier. The barrier would incorporate turbines to generate renewable energy and include road and rail tunnels, providing connections from Essex to a major new on the.
