Detours will be in place and motorists are asked to take extra care by following any temporary speed limits, signs and instructions from the traffic management team.
The 32-metre footbridge will be brought in as one piece and lowered into place by crane.
In the event of bad weather, the closure will instead take place overnight on Thursday 19 August.
