A tied-arch bridge combines features of an arch bridge and a suspension bridge. It uses horizontal thrust from both sides to support an arched structure, as in a regular arch bridge. But instead of an arch supporting the structure from below, the arch rises above the road, and vertical ties descend to increase the support of the decking.
These are also called bowstring bridges since they look like a bow from the side. This bow uses the tension of its vertical cables, together with the compression of the arch, to support the load and keep the bridge stable.
