Causeway Beach is basically the southern edge of the causeway that serves the Tsawwassen Ferry Terminal. I don't know how much intention went into building this beach, or whether it is just an artifact of the gravel-size material eroding out of the armored fill. Regardless, this beach would not have been here before the terminal was constructed - this was just the wide flats of Roberts Bank.
The beach has an impressive fetch to the south. Its orientation makes it unlikely that it has any significant source of coarse sediment, other than from itself. And it's not a uniform width - it undulates along the south side of the highway - in some places there is a wide backshore (little more than a rough gravel parking lot) and in others it narrows to nothing and the roadway is protected by newer riprap.
