The '''Gjemnessund Bridge''' ({{langx|no|Gjemnessundbrua}}) is a [[suspension bridge]] that crosses the Gjemnessundet [[strait]] between the mainland and the island of [[Bergsøya, Gjemnes|Bergsøya]] in [[Gjemnes Municipality]] in [[Møre og Romsdal]] county, [[Norway]]. The {{convert|1257|m|ft|adj=mid|-long}} bridge was the [[List of bridges in Norway by length|longest suspension bridge in Norway]] until the opening of the [[Hardanger Bridge]] in 2013, although it did not have the longest span ({{convert|623|m|disp=or}}), being eclipsed by the [[Askøy Bridge]].

Gjemnessund Bridge was opened in 1992, and has 21 spans with a maximum clearance to the sea of {{convert|43|m}}. It was built as part of the [[Krifast]] project, the mainland road connection of the city of [[Kristiansund (town)|Kristiansund]] (along with the [[Freifjord Tunnel]] and the [[Bergsøysund Bridge]]).<ref>{{Cite book |url=http://www.lotsberg.net/data/norway/bru.html |title=Norske bruer og viadukter |editor-last=Merzagora |editor-first=Eugenio A. |chapter=Road Viaducts & Bridges in Norway (> 500 m) |archive-url=https://web.archive.org/web/20150720222818/http://www.lotsberg.net/data/norway/bru.html |archive-date=2015-07-20 |url-status=dead |accessdate=2010-11-29}}</ref><ref>{{Cite web |title=Gjemnessund Bridge |url=http://en.broer.no/bro/index.php?ID=41 |url-status=dead |archive-url=https://web.archive.org/web/20110523005118/http://en.broer.no/bro/index.php?ID=41 |archive-date=2011-05-23 |access-date=2010-11-29 |publisher=Broer.no}}</ref><ref>{{Structurae|id=20008110|title=Gjemnessundbrua}}</ref>
Many bridges slowly deteriorate and need to be repaired because the salty [[seawater]] damages the [[concrete]] and the iron inside it. The Gjemnessund Bridge has had a problem with [[seabird]]s, whose [[manure]] contain salt and [[ammonia]]. The salt and ammonia damages the concrete. To prevent this, the bridge is cleaned, and the critical parts of the concrete are covered with an [[Elasticity (physics)|elastic]] membrane that protects the concrete against the manure and the harmful content.<ref name="tk1">{{Cite news |last=Bjørshol |first=Øivin |date=15 March 2004 |title=Krykkjeskit skader Gjemnessundbrua |url=http://www.tk.no/nyheter/article908606.ece |access-date=2008-11-13 |work=[[Tidens Krav]] |language=Norwegian}}</ref>
