Most　of　the　two-way　curved　arch　bridges,　which　were　constructed　created　in　China　in　1960s,　have　now　demonstrated　a　poor　structural　performance　at　monolithic　aspect.　Under　the　long-term　heavy　load　and　heavy　traffic,　more　or　less　structural　damage　exits　in　these　two-way　curved　arch　bridges　and　some　of　them　are　even　in　danger　to　collapse.　The　assessment　and　maintenance　of　these　dangerous　two-way　curved　arch　bridges　become　more　and　more　important.　In　this　paper,　based　on　the　structural　assessment　of　an　existing　damaged　two-way　curved　arch　bridge,　the　field　load　test,　structural　analysis　and　assessment　are　reported　in　details.　It　is　demonstrated　that,　the　structural　performance　of　the　bridge　can　be　evaluated　and　the　corresponding　service　status　can　be　assessed　by　use　both　load　test　and　structural　analysis　results.　The　similar　procedure　can　be　used　to　evaluate　the　structural　safety　of　other　existing　two-way　curved　arch　bridges.
