There will be a night-time closure of the Thames Path (9pm to 6am) in Reading from Thursday 22 August to Saturday 24 August.
The closure for the annual Reading Festival will start around Caveresham Bridge and end at Scours Lane near Tilehurst.
During the day walkers will see a temporary footbridge spanning the river near Scours Lane.
This first appeared in 2008 and replaces a temporary ferry where queues built up.
