=== Tied-arch bridge ===
{{Main|Tied-arch bridge}}

Also known as a bowstring arch, this type of arch bridge incorporates a tie between two opposite ends of the arch. The tie is usually the deck and is capable of withstanding the horizontal thrust forces which would normally be exerted on the abutments of an arch bridge.

The deck is suspended from the arch. The arch is in compression, in contrast to a suspension bridge where the [[catenary arch|catenary]] is in tension. A tied-arch bridge can also be a through arch bridge.
