Alexandra Bridge Provincial Park is a small park centred around the site of the original Cariboo Wagon Road bridge over the Fraser River.
The Alexandra Bridge was built across a narrow point in the Fraser River in 1926 for the Cariboo Highway. It replaced an 1863 bridge, which had been built for the Cariboo Wagon Trail during the gold rush. It is located 195 km east from Vancouver, near Spuzzum.
Most of the old Cariboo Highway through the Fraser Canyon is now part of the Trans-Canada Highway. But when the Trans-Canada was completed in 1962 another bridge was built across the Fraser a few kilometres away, and the Alexandra Bridge was decommissioned.
