This type of bridge has an [[arch]] whose base is at or below the deck, but whose top rises above it, so the deck passes through the arch. The central part of the deck is supported by the arch via suspension cables or tie bars, as with a [[tied-arch bridge]]. The ends of the bridge may be supported from below, as with a deck arch bridge. Any part supported from arch below may have spandrels that are closed or open.

The [[Sydney Harbour Bridge]] and the [[Bayonne Bridge]] are a through arch bridge which uses a truss type arch.
