巨加大桥朝鮮語:거가대교巨加大橋 Geoga daegyo */?)是连接韩国釜山广域市巨济岛跨海大桥。大桥总长8.2公里,总投资14469亿韩元,经过6年施工于2010年12月13日竣工[1][2]。大桥的开通将使原来从庆尚南道巨济市釜山加德岛的距离从原来的140公里缩短到60公里,所需时间也从2小时缩短到50分钟左右[3]

巨加大桥工程分为海底沉管隧道路段和2座斜拉桥路段两部分。韩国在此工程中首次引进沉管隧道施工方式。釜山加德岛至大竹岛的海底隧道总长为3.7公里,居落成當時世界最長的沉管式海底隧道,港珠澳大橋落成後成為世界第二長沉管式海底隧道。其沉管隧道设置在水底约48米处,是世界第二深的沉管式海底隧道[4]
