To　study　the　difference　of　the　technical　condition　rating　methods　for　highway　bridges　and　city　bridges　in　China,　a　comparison　analysis　of　the　rating　systems　of　the　Code　for　Maintenance　of　Highway　Bridges　and　Culverts　(JTG　H11-2004)　and　the　Technical　Code　of　Maintenance　for　City　Bridge　(CJJ　99-2003)　was　carried　out.　A　simple　RC　beam　bridge　and　a　concrete　filled　steel　tubular　arch　bridge　were　investigated　and　their　conditions　were　rated　by　the　two　codes,　and　the　rating　results　were　analyzed.　In　addition,　the　rating　methods　in　the　two　codes　were　compared.　The　results　show　that　both　of　them　adopt　the　member　weight　method　but　there　is　difference　in　detailed　approaches　and　contents;　the　rating　results　of　the　deck　systems,　the　superstructures　and　the　substructures　of　the　two　bridges　by　the　two　codes　agree　well,　while　the　rating　results　of　the　whole　bridges　are　quite　different　because　the　weighing　values　of　superstructures　and　substructures　in　the　two　codes　have　great　difference.　This　study　can　provide　reference　for　the　condition　rating　of　road　bridges　in　China.
