(a) The south draw of the S11 bridge near New Orleans shall open on signal if at least 48 hours notice is given. In case of emergency, the draw shall open within 12 hours and shall be kept in condition for immediate operation until the emergency is over.

(b) The draw of the Norfolk Southern Railroad Bridge across Lake Pontchartrain, mile 4.80 near Slidell, St. Tammany Parish, Louisiana shall be maintained as follows:

(1) The draw shall be maintained in the fully open-to-navigation position for vessels at all times, except during periods when it is closed for the passage of rail traffic or to perform periodic maintenance authorized in accordance with subpart A of this part.

(2) The draw shall be remotely operated by the drawtender at Norfolk Southern's drawbridge in Decatur, Alabama. The estimated duration that the bridge will remain closed for the passage of rail traffic is 10 to 15 minutes per operation.

(3) When a train approaches the bridge, the drawtender will initiate the bridge closing warning signal, consisting of radio calls via VHF-FM-channels 13 and 16 and activation of flashing red warning lights at each end of the span. The radio calls will be broadcast at five (5) minutes prior to bridge closing and at two (2) minutes prior to bridge closing. Photoelectric (infrared) boat detectors will monitor the waterway beneath the bridge for the presence of vessels.

(4) The drawtender will continuously monitor waterway traffic in the area using closed-circuit cameras mounted on the bridge. The draw will only be closed if the drawtender's visual inspection indicates that the channel is clear and there are no vessels transiting in the area. The drawtender will maintain constant surveillance of the navigation channel to ensure that no conflict with maritime traffic exists. Additionally, the draw will not be closed if the S11 bascule bridge that is located immediately west of the railroad bridge is in the open-to-navigation position. If two or more closed-circuit cameras are inoperable or if there is inclement weather, the draw will only be operated by a drawtender located on site at the bridge.

(5) At the end of the two-minute warning period, if no vessels have been detected by the drawtender, the draw closing sequence will automatically proceed.

(6) Upon passage of the train, the draw will be returned to the fully open-to-navigation position to allow marine traffic to pass. The warning lights will continue to flash red until the draw has returned to the fully open-to-navigation position at which time they will deactivate.

(7) After the passage of each train, the draw must be returned to its fully open-to-navigation position.

(8) To request openings of the draw when the bascule span is in the closed-to-navigation position, mariners may contact Norfolk Southern Railway via VHF-FM channel 13 or by telephone at the number displayed on the signs posted at the bridge.

(9) The draw will be operated locally if:

(i) Communication is lost between the drawbridge and the drawtender in Decatur, Alabama;

(ii) More than two closed-circuit cameras are not working;

(iii) The marine radio is inoperable;

(iv) Weather conditions warrant; or

(v) Ordered by the Coast Guard.

(c) The draw of the Greater New Orleans Expressway Commission Causeway shall open on signal if at least three hours notice is given; except that, the draw need not be opened for the passage of vessels Monday through Friday except Federal holidays from 5:30 a.m. to 9:30 a.m. and from 3 p.m. until 7 p.m. The draw will open on signal for any vessel in distress or vessel waiting immediately following the closures listed above.

§117.484   Pass Manchac.

The draw of the Canadian National/Illinois Central Railroad automated bridge, mile 6.7, at Manchac, operates as follows:

(a) The draw is not constantly manned and the bridge will normally be maintained in the open position, providing 56 feet vertical clearance above mean high tide to the raised tip of the bascule span for one-half the channel, and unlimited vertical clearance for the other half.

(b) Railroad track circuits will detect an approaching train and initiate bridge closing warning broadcasts over marine radio and over the Public Address (PA) system six (6) minutes in advance of the train's arrival. Navigation channel warning lights will be lit, and photoelectric (infrared) boat detectors will monitor the waterway beneath the bridge for the presence of vessels. The waterway approaches to the bridge will be monitored by closed circuit TV (CCTV) cameras.

(c) Activation of the warning broadcasts also activates a marine radio monitor in the Mays Yard (New Orleans switch yard). The yardmaster will continuously monitor marine radio broadcasts on the normal and emergency marine radio channels throughout the warning period and at all times the bridge is closed. The yardmaster will communicate with waterway users via the marine radio, if necessary.

(d) At the end of warning period, if no vessels have been detected by the boat detectors, and no interruptions have been performed by the yardmaster based on his monitoring of the marine radio and the CCTV, the bridge lowering sequence will automatically proceed.

(e) Upon passage of the train, the bridge will automatically open. Railroad track circuits will initiate the automatic bridge opening and closing sequences. (Estimated duration that the bridge will remain closed for passage of rail traffic is 10 to 12 minutes.) The bridge will also be manually operable from two locked trackside control locations (key releases) on the approach spans, one on each side of the movable span.

(f) The yardmaster will be provided with a remote EMERGENCY STOP button which, if pressed, will stop the bridge operation, interrupt the lowering sequence, and immediately return the bridge to the open position. The yardmaster will utilize this control feature in the event a vessel operator issues an urgent radio call to keep the waterway open for immediate passage of the vessel.
