APPENDIX 6.4.7-A2 <br /> Updated Weld County Road 13 structure to fix holes between abutments and bridge <br /> structure (see Figure 2). <br /> Updated Weld County Road 54 structure to fix similar errors in bridge geometry. <br /> - Lateral structure that was placed on Weld County Road 54 updated to more <br /> accurately reflect the surface of the road (see Figure 3). This was due to the <br /> CHAMP models lateral structure alignment wandering off the road centerline. <br /> Removed lateral structure on the CR-13 Split reach because it was deemed <br /> unnecessary for this analysis due to the fact that WCR 54 bridge provides a <br /> hydraulic control for the model, the effective flows did not overtop WCR54, and all <br /> flow remained in the main channel. <br /> -eam Cross Section(82282) <br /> 4820 <br /> :. /Sloping Abutments <br /> ❑Ineffective Flow Areas <br /> Ground Geometry <br /> S6G� Overbanks <br /> • Ruch Centedme <br /> 15cc 1550 1600 1650 1700 1750 taco <br /> honzontal Station(ft) '634.23.4821A3 <br /> Figure 2: CHAMP model WCR-13 structure showing gaps between the abutments and the <br /> structure, these gaps were fixed for this project along with some minor adjustments to the <br /> abutments. <br />
