The　development　of　concrete　arch　bridge　is　limited　by　its　heavy　self-weight　and　the　difficult　erection,　so　there　are　few　concrete　arch　bridges　built　in　recent　years.　This　paper　presents　an　innovative　conception　on　concrete　arch　bridge　design,　in　which　corrugated　steel　web　is　used　to　substitute　the　concrete　web　in　arch　ring.　Compared　with　concrete　arch　bridge,　the　arch　self-weight　can　be　lightened,　and　the　construction　can　be　simplified,　moreover,　it　makes　the　larger　span　concrete　arch　bridge　possible.　Taking　the　built　Chongqing　Wanzhou　Yangtze　River　Bridge　with　a　clear　span　of　420　m　and　the　Ningde　Lingdou　Bridge　with　clear　span　of　160　m　under　construction　as　prototype,　two　trail　designs　of　concrete　arch　bridge　with　corrugated　steel　webs　are　carried　out.　The　construction　methods　of　embedded　falsework　method　and　cantilever　method　are　discussed　in　the　trial　designs.　Analysis　results　show　that　the　self-weight　of　the　arch　ring　is　reduced　by　about　30%　in　the　trial　design.　It　proves　that　the　trial　design　is　feasible　for　it　will　lead　to　the　lower　requirements　for　the　foundation　and　substructure,　the　construction　procedure　will　be　greatly　simplified　and　construction　time　will　be　saved.
