Update 19 June 2025 5:39 pm

The concrete blocks were installed some time ago, to protect the banking, and used to have markers. We are arranging to have new markers put in place as soon as our work boat is available.  

In the meantime, please keep to the centre of the canal and pass slowly with care.

We will update this notice as soon as we have more information.  

Original 20 May 2025 9:15 am

There are some large concrete blocks in the canal, on the towpath side between Braunston Top Lock and the Western portal of Braunston Tunnel.

Some of these are below the waterline and so are causing an underwater obstruction.

We are currently exploring options to have these removed.

Please keep to the centre of the canal and pass slowly with care.

We will update this notice as soon as we have more information.
