OCTA I July 2016 r�� <br />VIASupplement J <br />Currently, minor design modifications to the bridge crossing include a double track <br />configuration (rather than single track), use of two catenary wires as opposed to one, and <br />the re -positioning of the bridge to north of the existing Old Pacific Electric Santa Ana River <br />Bridge (as opposed to the south which was the previously -contemplated location of the <br />new bridge). <br />To assess these minor design modifications, visual simulations were prepared for <br />vantages (e.g. from the south) similar to those identified in the 2015 EA. In addition, <br />because the bridge is re -positioned north of the Old Pacific Electric Santa Ana River <br />Bridge, an additional vantage was captured from the north. Figure 5 illustrates the key <br />observation points that were used for the two simulations. <br />Figure 5 — Key Observation Points <br />Figure 6 presents the revised visual simulation for the minor design modifications at the <br />Santa Ana River Bridge from the same vantage as provided in the 2015 EA. As shown in <br />Figure 6 (north -facing), the existing Old Pacific Electric Santa Ana River Bridge generally <br />obstructs the bridge with the exception of the catenary supports, guard rail, and bridge <br />81 Page <br />
