{{anchor|Open-spandrel deck arch bridge}}
This type of bridge comprises an arch where the deck is completely above the arch. The area between the arch and the deck is known as the [[spandrel]]. If the spandrel is solid, usually the case in a masonry or stone arch bridge, the bridge is called a ''closed-spandrel deck arch bridge''. If the deck is supported by a number of vertical columns rising from the arch, the bridge is known as an ''open-spandrel deck arch bridge''. The [[Alexander Hamilton Bridge]] is an example of an open-spandrel arch bridge. Finally, if the arch supports the deck only at the top of the arch, the bridge is called a [[cathedral arch|cathedral arch bridge]].<ref name="aspire2010w">{{cite web|url=http://www.aspirebridge.org/pdfs/magazine/issue_13/galena_creek_win10.pdf |title=Nevada's Galena Creek Bridge |last=Durski |first=Brad F. |date=Winter 2010 |access-date=18 June 2012 |work=Aspire |publisher=Precast/Prestressed Concrete Institute |url-status=dead |archive-url=https://web.archive.org/web/20100216230014/http://www.aspirebridge.org/pdfs/magazine/issue_13/galena_creek_win10.pdf |archive-date=16 February 2010 }}</ref>
