Average Daily Traffic (veh/hr/day): Design/Future: 5600 Existing: 2300 General Project Narrative: Bridge #38 over Muddy Creek on SR 1493 (Frye Bridge Road) was deamed structurally deficient and is being replaced with a new structure. The existing 9 span concrete bridge is being replaced with a 4 span 39" concrete box beam structure. The new bridge will be constructed parallel to the existing bridge on the dwonstream side which will allow traffic to be maintained on the existing bridge until the new bridge and associated roadway approaches can be completed. The proposed bridge will have three piers and will span the creek, eliminating the placement of a pier in the water thus greatly reducing scour potetial and debris potential as compared to the existing bridge. The existing structure has eight piers with one pier residing in the center of the creek. The drainage was designed to utilize as many existing outfalls and existing ditches as possible. Newly constructed lateral and cut ditches were designed to produce non -erosive velocities. Rip rap outlet pads and preformed scour holes were used at pipe outlet locations to reduce velocity and promote sheet flow. Deck drains were placed on the proposed structure to control spread but were not outleted over the creek. The deck drains were outleted onto rip rap dissipator pads away from the creek to avoid direct discharge into surface waters.
