From the start of each closing procedure until completion of the opening procedure vessels will be prohibited from transiting the Thames Barrier. Most closures are for approximately 2½ hours over the respective low waters.

No vessel is to pass Margaretness inward bound or Blackwall Point outward bound once a Thames Barrier closure has commenced unless authorised by London VTS.

GATE CLOSURES:
In addition to the full Thames Barrier closures there will be frequent closures of individual gates for maintenance and training purposes, subject to a programme issued by the Environment Agency. The closure of individual gates will change the spans available for navigation. Information regarding these gate closures will be promulgated by London VTS on VHF Channel 14 routine river broadcasts.

During each full Thames Barrier or individual gate closure(s), illuminated red crosses will be displayed on both sides of the gate(s) indicating that the gate(s) are closed to navigation.
