The repairs to the lock gate and cill at Lock 3 were completed successfully and on time.
Unfortunately there is now a residual problem of a build up of excess silt around Lock 4 which has resulted in the navigation having to remain closed.
The silt is currently being tested for contamination and disposal options are being urgently investigated. The navigation will be re-opened by 16th March.
We will do everything we can to reduce this timescale and sincerely apologise for any inconvenience caused.
