A £5.2million capital maintenance programme for Environment Agency navigation infrastructure has been announced.
The Environment Agency is releasing its annual schedule of improvements for many of its structures along the Thames, between St John's Lock in Lechlade, Gloucester, and Teddington Lock in southwest London. This will help to ensure safe navigation along this iconic river for boating communities and many other river users.
The majority of work will begin in November this year, carrying through to March 2021. The Environment Agency gives several weeks' notice, so that river users can plan any winter trips. Major work will be carried out at 10 of the Environment Agency's 45 lock sites, some of which will require a formal closure.
Peter Collins, a capital investment programme manager for the Environment Agency, said:
Locks, weirs and other navigation infrastructure make recreational and commercial boating on the Thames possible.
This multi million pound investment programme, by the Environment Agency, allows our team of engineers, craftsmen and contractors to ensure that everything remains in safe working order.
Our in house carpenters are making new timber lock gates from sustainable sources for Day's Lock, Dorchester in Oxfordshire. The new gates at Molesey Lock in Surrey will be made from steel, but in keeping with the tradition of a Thames lock.
Four locks that will require a formal closure between 2 November 2020 and 19 March 2021 are:
- Days Lock, near Dorchester, Oxfordshire: replacing lock gates and refurbishing parts of the lock chamber and lock surround.
- Cookham Lock, Berkshire: refurbishing tail gate cill, lock side and head landings.
- Abingdon Lock, Oxfordshire: upgrading the existing tail landing to make it more resilient to winter flooding and easier for canoes to get in and out of the water.
- Molesey Lock, Surrey: replacing lock gates, improving pedestrian access and refurbishing parts of the lock chamber.
