The new bridge design was developed in HEC-RAS by optimizing the area of flow beneath the bridge to alleviate overtopping, while considering realistic constraints such as\u00a0 roadway line of site and encroachment onto private property. The design standard used was to lower the energy grade line beneath the top chord of the bridge.<\/p>\n
The new bridge was designed to have a 65 ft span length.\u00a0 The top chord of the bridge will be at an elevation of 15.1 ft, an increase in 3 ft. The bottom chord will be at an elevation of 12.1 ft. The channel width will be expanded 7.5 ft\u00a0 on each side to coincide with the new span length. The left and right banks will be expanded by 10 ft in either direction and will now be located at station 200 and 239, respectively The new bridge design was developed in HEC-RAS by optimizing the area of flow beneath the bridge to alleviate overtopping, while considering realistic constraints such as\u00a0 roadway line of site and encroachment onto private property.
