Constructed a 100 foot single span portable steel bridge over the new location of Drywood Creek.  Bridge designed and fabricated to meet Canada Highway Bridge Design Code and will accomadate legal load limits.  Work was undertaken early spring of 2015 and the structure and approaches were 'tested' by numerous high water events. Location of bridge was approximately 5 km NE of Twin Butte AB.  Work entailed removing and salvaging the existing 18.3 metre single span Bailey Bridge, removal of all substructure for that bridge.  Only then was the new structure located over the new location of Drywood Creek.  This work site was isolated from the channel during operations.
