'''Bajer Bridge''' is located between the Vrata and Oštrovica interchanges of the A6 motorway in Gorski Kotar, Croatia, spanning Lake Bajer. It is {{convert|520|m}} long. The bridge consists of two parallel structures: The first one was completed in 1995, and the second one in 2008.<ref name="Gradimo-Najvredniji">{{cite web | publisher = Gradimo | language = Croatian | url= http://www.gradimo.hr/Najvrjedniji-mostovi-u-Hrvatskoj-izgradeni-izmedu-prvoga-i-petoga-Sabora-hrvatskih-graditelja/hr-HR/13069.aspx | title = Najvrjedniji mostovi u Hrvatskoj izgrađeni između prvoga i petoga Sabora hrvatskih graditelja |trans-title=The most valuable bridges in Croatia completed between the first and the second Congress of Croatian Builders | author= Zvonimir Marić | accessdate = October 12, 2010| archiveurl= https://web.archive.org/web/20100914062048/http://www.gradimo.hr/Najvrjedniji-mostovi-u-Hrvatskoj-izgradeni-izmedu-prvoga-i-petoga-Sabora-hrvatskih-graditelja/hr-HR/13069.aspx| archivedate= 14 September 2010 | url-status= live}}</ref> The bridge is tolled within the A6 motorway ticket system and there are no separate toll plazas associated with use of the bridge.<ref name="HAC-Monografija-Bajer">{{cite book | publisher=Hrvatske autoceste | url=http://www.hac.hr/brosure/monografija/virtualMagazine.html | title=Croatian Motorways | pages=360–361 | format=PDF | isbn=978-953-7491-09-3 | year=2007 | accessdate=September 11, 2010 | archiveurl=https://web.archive.org/web/20100818140354/http://www.hac.hr/brosure/monografija/virtualMagazine.html | archivedate=2010-08-18 | url-status=dead }}</ref> The bridge was constructed by Viadukt.<ref name="Viadukt-Bajer">{{cite web | publisher = Viadukt | url= http://www.viadukt.hr/projekti/objekti/most-bajer-autocesta-rijeka-zagreb | title = Bridge "Bajer" Rijeka - Zagreb highway | accessdate = October 12, 2010}}</ref>
==Structure description== At this location the motorway route follows a horizontal curve of {{convert|2006|m|adj=on}} radius. Transversal grade of the deck is constant and equal to 2.5%, while elevation grade of the bridge is constant at 0.835%, sloping down towards Oštrovica. The bridge is a box girder structure supporting the deck across 10 spans: {{convert|42.63|m|abbr=on}} + 8 x {{convert|50.16|m|abbr=on}} + {{convert|42.63|m|abbr=on}}.<ref name="HAC-Monografija-Bajer"/><ref name="Viadukt-Bajer"/> Since the elevation of the bridge lies {{convert|41|m}} above the average water level of Lake Bajer, incremental launching of the bridge was executed without use of any auxiliary piers. The main longitudinal girders comprise box cross-section and were divided in 19 sections each (2 x {{convert|27.94|m|abbr=on}} + 15 x {{convert|25.08|m|abbr=on}} + 2 x {{convert|27.94|m|abbr=on}}). Piers of the bridge comprise a {{convert|6.6|m|adj=on}} by {{convert|3.1|m|adj=on}} box cross-section with {{convert|30|cm}} thick walls. Bridge abutments and shore piers have shallow foundations, while those piers located within the lake have foundations executed on groups of six piles each. The piles are circular in cross section, {{convert|1.5|m}} in diameter, and are connected with beam cap slabs measuring {{convert|8.5|m|abbr=on}} x {{convert|9.5|m|abbr=on}} x {{convert|2.5|m|abbr=on}}.<ref name="Gradimo-Najvredniji"/><ref name="Građevinar-Postignuća">{{cite news | newspaper = Građevinar | language = Croatian | url= http://hrcak.srce.hr/file/16818 | format= PDF | title = Najveća postignuća u građenju mostova u Hrvatskoj |trans-title=The greatest bridge-building achievements in Croatia | first= Zvonimir | last= Marić | first2= Damir | last2= Tkalčić | date= February 20, 2003 | accessdate = October 12, 2010}}</ref>
==Traffic volume== Traffic is regularly counted and reported by Autocesta Rijeka–Zagreb, operator of the viaduct and the A6 motorway where the structure is located, and published by Hrvatske ceste. Substantial variations between annual (AADT) and summer (ASDT) traffic volumes are attributed to the fact that the bridge carries substantial tourist traffic to the Adriatic resorts. The traffic count is performed using analysis of motorway toll ticket sales.<ref name="HC-promet">{{cite news|newspaper=Hrvatske Ceste |url=http://www.hrvatske-ceste.hr/WEB%20-%20Legislativa/brojenje-prometa/CroDig2009.pdf |title=Traffic counting on the roadways of Croatia in 2009 - digest |date=May 1, 2010 |url-status=dead |archiveurl=https://web.archive.org/web/20110721100545/http://www.hrvatske-ceste.hr/WEB%20-%20Legislativa/brojenje-prometa/CroDig2009.pdf |archivedate=2011-07-21 }}</ref>
