Avon Barriers: in-river works almost complete
The Avon Barriers Project has seen some fantastic progress in the last month, and construction of both fish passes is due to be completed by the end of this week (14th October). The temporary coffer dams constructed to create dry working areas are due to be removed on Monday 17th October, and the passes will be fully operational for the first time.
The task of site demobilisation can then begin, including removal of the temporary access roads from the river channel at each site. It is hoped that this can be achieved by the end of October.
The following photos provide a visual update:

The pass was designed to allow for natural introduction of material into the channel, and during a recent high water event the river began that process
Installation of the final few concrete blocks is almost complete at the Millheugh site
