[[File:Pentelehíd.jpg|thumb|The [[Pentele Bridge (Hungary)|Pentele Bridge]] is an example of a basket handle arch. Seen from one end, the two arches take the form of a handle.]]
The through arch bridge usually consists of two ribs,<ref>{{Cite web |title=Concrete Arch Bridges |url=http://www.dot.state.oh.us/Divisions/Engineering/Structures/bridge%20operations%20and%20maintenance/PreventiveMaintenanceManual/BPMM/archbridges/concbridges.htm |access-date=December 16, 2015 |website=www.dot.state.oh.us |publisher=[[Ohio Department of Transportation]] |quote=The through arch (or rainbow arch) usually consists of two arch ribs that extend well above the roadway on each side of the bridge.}}</ref> although there are examples like the [[Hulme Arch Bridge]] of through arches with a single rib. When the two arches are built in [[Parallel (geometry)|parallel]] planes, the structure is a parallel rib arch bridge. When the two arch ribs lean together and shorten the distance between the arches near the top, the span is a basket handle arch bridge.<ref>{{Cite journal |last1=Zhang |first1=Xiangdong |last2=Zhang |first2=Bin |last3=Jiang |first3=Lizhong |last4=Xie |first4=Mowen |date=November 8, 2013 |title=Load test design and stability analysis of basket handle arch bridge with reinforced concrete |journal=Advanced Materials Research |volume=838-841 |pages=1009–1013 |url=http://www.scientific.net/AMR.838-841.1009 |access-date=December 16, 2015 |publisher=Trans Tech Publications, Switzerland|doi=10.4028/www.scientific.net/AMR.838-841.1009 |s2cid=109262734 |url-access=subscription }}</ref>
