The closures will be confirmed and promulgated by London VTS from 24 hours in advance of the operation by VHF radio on routine river broadcasts.
From the start of each closing procedure until completion of the opening procedure vessels will be prohibited from transiting the barrier. Most closures are for approximately 2½ hours over the respective low waters.
The amber flashing lights on top of the barrier warning notice boards situated at Barking below the barrier, and at Brunswick and Blackwall Point above the barrier will be operated 30 minutes before each closure, and the red flashing lights on commencement of the closure until the barrier is reopened for navigation.
GATE CLOSURES
In addition to the full barrier closures there will be frequent closures of individual gates, subject to a programme issued by the Environment Agency, Thames Region. The closure of individual gates will change the spans available for navigation.
Information regarding these gate closures will be given by London VTS on VHF Channel 14 routine river broadcasts.
A copy of the six monthly daily programme may be obtained from our website under Navigational Safety/Marine Safety or by applying in writing to the E.A. Area Manager, Thames Barrier, Eastmoor Street, London SE7 8LX.
During each full barrier or individual gate closure(s), illuminated red crosses will be displayed on both sides of the span(s) indicating that the span(s) are closed to navigation.
NOTES:
(1) ANY ADDITIONAL BARRIER CLOSURES FOR TEST PURPOSES WILL BE PROMULGATED BY SEPARATE NOTICES TO MARINERS ISSUED 28 DAYS IN ADVANCE OF SUCH CLOSURES.
(2) THE BARKING BARRIER WILL BE CLOSED AT THE SAME TIME AS THE THAMES BARRIER.
