Planned lock closures: updated 14 February 2020
The Environment Agency carries out a programme of works on the River Thames every year between October and Easter. This often results in the closure of a number of locks for relatively long periods.
The Environment Agency publishes the first issue of the programme in August each year. This is so that river users can plan their winter cruising and boat movements well in advance.
This programme of work is subject to change, due to weather and other circumstances. Revised issues of the programme of works are published throughout the winter, so river users can keep up to date. To receive this information, sign up to the email update service.
The following locks will be closed during the 2019 to 2020 investment programme. The locks will be closed from the first date listed and re-open on the day after the final date:
|4 November 2019 to 31 March 2020||Hambleden Lock||Replacing tail layby fender timbers, including an additional line of fenders at the raised section of the layby. The tail layby is currently unsafe to use therefore it, and the lock, will remain closed for the duration of this updated closure. Lock passage maybe possible when a lock keeper is on duty.|
|14 January 2020 to 31 March 2020||Rushey Lock||Creating a new head layby walkway and reconstructing the water point building on the layby.|
|2 March 2020 to 31 March 2020||Boulters Lock||Structural survey of the vehicle bridge over the tail lock cut.|
