Traffic signals and gates are located in a control panel at the southeast corner of the bridge. <br />Mech/Elect (06/02/2021) Some control panels are either missing labels or have labels that are fading. Some control panels exhibit <br />minor corrosion. <br />(5/9/2023) Condition still present. <br />See notes in Element 604. <br />The interlocking system consists of limit switches that regulate the sequence of the traffic equipment and movable span operation. <br />The navigation channel is in Span 2. The pier protection consists of 3 timber dolphins upstream of Pier 2 and 2 timber dolphins <br />downstream. There is also at timber dolphin along the channel bank on each side of Abutment 3. <br />The dolphins (total 7) appear in good condition and there was no drift accumulating at the dolphins or the pier. <br />Navigation lights required by Coast Guard regulation are mounted on dolphins, two upstream and two downstream of Pier 2 and one <br />on each side of Abutment 3. <br />Mech/Elect (06/02/2021) One of the navigation lights is burned out. <br />(5/9/2023) Condition still present. <br />Utility power to the bridge is delivered to the west side of the bridge and provided by means of a submarine cable to the pivot pier. <br />The power supply is 240 Volts AC. There is no backup generator on-site. <br />Mech/Elect (06/02/2021) None of the electrical enclosures have arc flash labels. Some of the electrical enclosures exhibit minor <br />corrosion. <br />The top hinge for the pole mounted electrical service equipment enclosure was missing. <br />(5/9/2023) Condition still present. <br />Single battery powered traffic gates are located at each end of the bridge. Each gate has three flashing red lights mounted along the <br />length of the gate arm. Alarm bells are mounted adjacent to the traffic gates.
