Any vessel which requires an opening of the draw of this bridge shall establish contact by radiotelephone with the remote drawbridge operator on VHF-FM Channel 13 in Omaha, Nebraska. To establish contact, the vessel shall key the VHF-FM radio microphone four times in five seconds and listen for an acknowledgement tone. The remote drawbridge operator will then establish normal verbal radio communication on VHF-FM Channel 13 and advise the vessel whether the requested span can be immediately opened and will maintain constant radio contact with the vessel until the requested span has opened and vessel passage has been completed. The bridge is equipped with a Photoelectric Boat Detection System to prevent the span from lowering if there is an obstruction under the span. If the drawbridge cannot be opened immediately, the remote drawbridge operator will notify the calling vessel and provide an estimated time for a drawspan opening.

(2) High velocity flow procedures. The area from mile 118.2 to mile 125.4 is a regulated navigation area as described in § 165.817. During periods of high velocity flow rate of 70,000 cubic feet per second or greater at the Murray Lock and Dam, mile 125.4, downbound vessels which require that the draw of this bridge be opened for unimpeded passage shall contact the remote drawbridge operator as described in paragraph (b)(1) of this section either before departing Murray Lock and Dam or before departing the mooring cells at mile 121.5 to ensure that the drawspan is opened well in advance of arrival at the bridge. The remote drawbridge operator shall immediately respond to the vessel's contact, ensure the drawspan is open for passage, and ensure that it remains in the open to navigation position until the downbound vessel has safely passed through. If it cannot be opened immediately for unimpeded passage in accordance with § 165.817, the remote drawbridge operator will notify the downbound vessel and provide an estimated time for a drawspan opening. Upbound vessels shall request openings in accordance with the normal flow procedures as set forth in paragraph (b)(1) of this section. The remote drawbridge operator shall keep these approaching vessels informed of the position of the drawspan at all times until safe passage is completed.

(c) Across the Arkansas Waterway, the draw of the Van Buren Railroad Drawbridge, mile 300.8 at Van Buren, Arkansas, is maintained in the open position except as follows:

(1) When a train approaches the bridge, amber lights attached to the bridge begin to flash and an audible signal on the bridge sounds. At the end of 10 minutes, the amber light continues to flash; however, the audible signal stops and the draw lowers and locks if the photoelectric boat detection system detects no obstruction under the span. If there is an obstruction, the draw opens to its full height until the obstruction is cleared.

(2) After the train clears the bridge, the draw opens to its full height, the amber flashing light stops, and the mid channel lights change from red to green, indicating the navigation channel is open for the passage of vessels.

(a) The draw of the automated Burlington Northern Santa Fe railroad bridge, mile 88.8 at Beardstown, Illinois, operates as follows:

(1) The draw is normally maintained in the fully open position, displaying a green light to indicate that vessels may pass.

(2) When a vessel is approaching and the draw is in the open position, contact shall be established by radiotelephone with the remote operator to assure that the draw remains open until passage is complete.

(3) When a vessel is approaching and the draw is in the closed position, contact shall be established by radiotelephone with the remote operator. If the draw cannot be opened immediately, alternate flashing red lights are displayed. If the draw can be opened immediately, flashing amber lights are displayed.

(4) When a train approaches the bridge and the draw is in the open position, the operator shall activate alternate flashing red lights on top of the draw, sound four short blasts, and scan the river on radar to determine whether any vessel is approaching the bridge. The remote operator shall also broadcast that the draw is closing. If a vessel or vessels are approaching the bridge within one mile, as determined by radar scanning, response to radio broadcast, or electronic detector, the flashing red lights shall be changed to flashing amber and the operator shall keep the draw in the fully open position until the vessel or vessels have cleared the bridge. If no vessel is approaching the bridge or is beneath the draw, the draw may be lowered and locked in place.

(5) After the train has cleared the bridge, the draw shall be raised to its full height and locked in place, the red flashing lights stopped, and the draw lights changed from red to green.

(b) The draw of the Chessie Railroad Bridge, mile 254.1, at Seneca, Illinois, operates as follows:

(1) The draw is normally maintained in the fully open position, displaying green mid-channel lights to indicate the span is fully open.

(2) When a train approaches the bridge and the draw is in the open position, the train will stop, train operator shall walk out on the bridge and scan the river for approaching vessels.

(3) If a vessel is approaching the bridge, the draw will remain open. The vessel shall contact the train operator on VHF-FM channel 16 and the train operator shall keep the draw in the fully open position until the vessel has cleared the bridge.

(4) If no vessels are observed, the train operator initiates a five minute warning period on VHF-FM radio channel 16 before closing the bridge. The train operator will broadcast the following message: “The Chessie Railroad Bridge at Mile 254.1, Illinois River, will close to navigation in five minutes.” The announcement is repeated every minute counting down the time remaining until closure.

(5) At the end of the five minute warning period, and if no vessels are approaching the bridge, the train operator shall sound the siren for 10 seconds, activate the alternate flashing red lights on top of the draw, then lower and lock the draw in place. Red lights shall continue to flash to indicate the draw is closed to navigation.

(6) After the train has cleared the bridge, the draw shall be raised to its full height and locked in place, the red flashing lights stopped, and the draw lights changed from red to green.

(c) The draws of the McDonough Street Bridge, mile 287.3; Jefferson Street bridge, mile 287.9; Cass Street bridge, mile 288.1; Jackson Street bridge, mile 288.4; and Ruby Street bridge, mile 288.7; all of Joliet, shall open on signal, except that they need not open from 7:30 a.m. to 8:30 a.m. and from 4:15 p.m. to 5:15 p.m. Monday through Saturday.

(d) The drawspan of the Elgin, Joliet and Eastern Railway bridge, mile 290.1 at Lockport, Illinois, is operated by remote operator located at the Elgin, Joliet & Eastern offices in Homewood, Illinois as follows:

(1) The drawspan is normally maintained in the fully open to navigation position displaying green center span navigation lights to indicate that the drawspan is fully open.

(2) The bridge is equipped with the following:

(i) A radiotelephone link direct to the remote operator;

(ii) A radar antenna on top of the drawspan capable of scanning the river, one mile upstream and one mile downstream;

(iii) Infrared boat detectors under the drawspan, to allow the remote bridge operator to detect vessels under the drawspan;

(iv) Electronic motion detectors under the drawspan to allow the remote bridge operator to detect vessel movement under the drawspan;

(v) A siren for sound signals; and

(vi) Red and green center span navigation lights.

(3) The remote bridge operator shall maintain a 24 hour VHF marine radio watch for mariners to establish contact as they approach the bridge to ensure that the drawspan is open or that it remains open until passage of river traffic is complete.

(4) When rail traffic approaches the bridge, and the drawspan is in the open position, the remote bridge operator initiates a one minute warning period before closing the drawspan. During this warning period, the remote operator shall broadcast at least twice, via marine radio, that: “The drawspan of the EJ&E Railroad bridge will be lowered in one minute.” A siren on the bridge sounds for 20 seconds, to warn anyone on or under the bridge that the drawspan will be lowered.

(5) If a vessel is approaching the bridge upbound or, departing the Lockport Lock and Dam at mile 291.1, downbound, with intentions of passing through the drawspan, they shall respond to the remote bridge operators' marine radio broadcast, or initiate radio contact, indicating their proximity to the bridge and requesting an opening of the drawspan or that the drawspan remain open until the vessel passes. If any approaching vessel is detected or if a radiotelephone response is received, the remote operator shall not close the drawspan until the vessel or vessels have cleared the bridge.

(6) At the end of the one minute warning period, if no river traffic is approaching or under the drawspan, the remote bridge operator may begin lowering the drawspan. Navigation lights located at the center of the drawspan change from green to red when the drawspan is not in the fully open to navigation position. The drawspan takes approximately 90 seconds to lower.

(7) If the presence of a vessel or other obstruction is discovered approaching or under the drawspan, during the lowering sequence, before the drawspan is fully lowered and locked, the drawspan shall be stopped and raised to the fully open position. When the vessel or obstruction has cleared the drawspan, the remote operator shall confirm that the channel is clear and reinitiate the one minute warning cycle before lowering the drawspan.

(8) If no marine traffic is present the drawspan may be lowered and seated. When the drawspan is lowered and locked in the closed to navigation position, the remote bridge operator periodically broadcasts, via marine radio, that: “The drawspan of the EJ&E Railroad bridge is closed to navigation.”

(9) Failure of the radar system, radio telephone system, infrared boat detectors or electronic motion sensors shall prevent lowering the drawspan from the remote location.

(10) when rail traffic has cleared the bridge, the remote bridge operator shall raise the drawspan to the fully open to navigation position. When the drawspan is raised and in the fully open to navigation position, the remote bridge operator broadcasts, at least twice, via marine radio, that: “The drawspan of the EJ&E Railroad bridge is open to navigation.” The center drawspan navigation lights change from red to green when the drawspan is fully open to navigation.

(a) Elgin, Joliet, and Eastern Railroad Bridge, 0.68, over the Indiana Harbor Canal need not have a drawtender in continued attendance at the bridge. Ten minutes before the bridge is lowered for train traffic a crewmember from the train will initiate a SECURITE call on VHF-FM Marine Channel 16 that the bridge will be lowering for train traffic and invite any concerned mariners to contact the crewmember on VHF-FM Marine Channel 12. The crewmember will also visually monitor for vessel traffic and listen for the standard bridge opening signal of one prolonged blast and one short blast from vessels already transiting the waterway. After the ten minute warning, another SECURITE shall be made on VHF-FM Marine Channel 16 that the bridge will be lowering for rail traffic, five minutes before lowering. Once the draw tender is satisfied that it is safe, the bridge will be lowered for rail traffic. Once the rail traffic has cleared the bridge, the bridge shall be raised and locked in the fully open to navigation position.

(b) Elgin, Joliet, and Eastern Railroad Bridge, mile 1.89, over the Indiana Harbor Canal need not have a drawtender in continued attendance at the bridge.
