Since　the　first　edition　of　the　AASHTO　Guide　Specifications　for　Horizontally　Curved　Steel　Girder　Highway　Bridges　was　published　in　1980,　there　have　been　two　more　editions　including　many　revisions　to　the　specifications.　Some　changes　were　based　on　valid　research　results　and　others　were　based　on　limited　or　uncertain　research　results　and　information.　The　current　edition　of　the　specifications　contains　provisions　that　may　result　in　unreasonably　conservative　load　capacity　ratings.　In　this　paper,　the　results　of　field　tests　and　analyses　conducted　on　the　Veterans＇　Memorial　curved　steel-box　girder　bridge　are　discussed.　Test　and　analytical　results　show:　(1)　current　AASHTO　guide　specifications　regarding　the　first　transverse　stiffener　spacing　at　the　simple　end　support　of　a　curved　girder　may　be　too　conservative　for　bridge　load　capacity　ratings;　(2)　current　AASHTO　guide　specifications　may　greatly　overestimate　the　dynamic　loadings　of　curved　box　girder　bridges　with　long　span　lengths;　and　(3)　a　plane　grid　finite-element　model　of　about　20　elements　per　span　in　the　longitudinal　direction　can　be　used　to　analyze　curved　multigirder　bridges　with　external　bracings　located　only　over　supports.　The　research　results　are　instructive　and　applicable　to　bridge　design　and　bridge　load-rating　activities.　©　2008　ASCE.
