Subpart B—Specific Requirements
Kansas

§ 117.411   Missouri River.

(a) The draws of the bridges across the Missouri River from the mouth to Sioux City, Iowa, shall open on signal; except during the winter season between the date of closure and date of opening of the commercial navigation season as published by the Army Corps of Engineers, the draw need not open unless at least 24 hours advance notice is given.

(b) The lift span of the A-S-B highway and railroad bridge, Mile 365.6, between Kansas City, Kansas, and Kansas City, Missouri, is operated from a remote location. Radiotelephone contact may be established with the remotely located bridge/train controller to request bridge openings. The bridge is also equipped with a directional microphone and horn to receive and deliver signals to vessels not equipped with a radiotelephone. Closed circuit TV cameras located at the bridge enable the remotely located bridge/train controller to view both river traffic and the bridge itself.

(1) When an approaching vessel requires a bridge opening, contact shall be established with the bridge/train controller by radiotelephone or appropriate signals prescribed in §117.15.

(2) The bridge/train controller will confirm by radiotelephone or sound signal that the bridge will open promptly.

(3) When rail traffic is on bridge, the bridge/train controller will inform the vessel that bridge cannot be opened and will also give an approximate time of bridge opening via radiotelephone. The bridge/train controller will indicate via sound signals that lift span cannot be opened if the vessel doesn't have a radiotelephone, or if radiotelephone is not used.

(4) When the bridge is clear of rail traffic, the bridge/train controller will advise the waiting vessel by radiotelephone or sound signal of the intended opening. The lift span will be raised to its full height, and the midchannel bridge lights will change from red to green.

(5) The bridge/train controller will monitor the vessel's passage via closed circuit TV and radiotelephone until it has cleared the bridge.

(6) When the vessel has cleared the draw, midchannel bridge navigation lights will change from green to red and the lift span will be lowered to the closed-to-navigation position.
