Alexander Bridge is the name of a locality, and bridges over the Blackwood River in the South West of Western Australia.
The locality had a range of groups of people from the area involved in sports clubs, usually from communities very close such as Witchcliffe.
The first bridge was built in 1897 and destroyed in a 1982 flood.
It has camping facilities, and is similar to other bridge locations on the river like Sues Bridge, which is in National Park
