ACKNOWLEDGMENTSpecial thanks to Roger Wiebusch, Bridge Administrator, Western Rivers Operations, Saint Louis,

for his many contributions to, and his time spent reviewing, this material.



• HISTORICALLY, AID VERIFIERS HAVE HAD A TOUGH TIME DESCRIBING BRIDGE DISCREPANCIES AND ACCURATELY IDENTIFYING THE LOCATION OF THE DISCREPANCIES

• THE COAST GUARD BRIDGE ADMINISTRATOR IS RESPONSIBLE FOR CONTACTING THE OWNERS OF BRIDGES WITH DISCREPANCIES BASED ON THE INFORMATION THE AUXILIARISTS REPORT ON THE BRIDGE VERIFICATION WORKSHEETS

• WITHOUT COMPLETE AND ACCURATE INFORMATION, THE BRIDGE ADMINISTRATOR CANNOT DO HIS JOB OF FOLLOWING UP ON AUXILIARY REPORTS

INTRODUCTION AND BACKGROUND

THE PURPOSE OF THIS TRAINING PRESENTATION IS TO PROVIDE 8WR AUXILIARY AID VERIFIERS WITH THE INFORMATION NEEDED TO

COMPLETELY AND ACCURATELY REPORT BRIDGE DISCREPANCIES



GENERAL BRIDGE LIGHTING REQUIREMENTS

• BRIDGE LIGHTING IS REQUIRED: AS PRESCRIBED BY THE COAST GUARD DISTRICT COMMANDER FOR BRIDGES IN

NAVIGABLE WATERWAYS FROM SUNSET TO SUNRISE IN PERIOD OF REDUCED VISIBILITY (LESS THAN ONE MILE) TO BE VISIBLE FOR ONE MILE

• CLEARANCE GAUGES: SHOULD BE READABLE FOR ONE-HALF MILE ARE MAINLY FOUND ON FIXED BRIDGES READING AT THE WATER LEVEL IS THE CLEARANCE FROM THE WATER TO THE

MINIMUM LOW STEEL ELEVATION OF THE BRIDGE SPAN (FOR MOVEABLE BRIDGES, THE READING SHOWS THE CLEARANCE WHEN THE BRIDGE IS IN THE CLOSED POSITION.)

• ANYONE CAN, AND SHOULD REPORT DISCREPANCIES HOWEVER, VERIFICATIONS MUST BE SUBMITTED BY A QUALIFIED AID VERIFIER



• THE CENTER OF THE MAIN CHANNEL AND ALTERNATE CHANNELS (IF ANY) ARE MARKED USING 360 DEGREE FIXED GREEN LIGHTS WHICH FORM A RANGE IN THE CENTER OF THE SPAN. THESE ARE CALLED:

– "MAIN CHANNEL CENTER LIGHTS" OR "ALTERNATE CHANNEL CENTER LIGHTS"

• IF THERE IS AN ALTERNATE CHANNEL, THEN THE MAIN CHANNEL IS MARKED BY THREE VERTICAL 180 DEGREE FIXED WHITE LIGHTS LOCATED ABOVE THE GREEN MAIN CHANNEL CENTER LIGHT. THESE ARE CALLED:

– "MAIN CHANNEL LIGHTS"

Note: Bridges display lights that are specifically defined by Coast Guard permit. The lighting configurations may vary from the general descriptions in this presentation. Example: A Saint Louis bridge displays Main Channel Lights with flashing green characteristics (versus fixed white characteristics).



• BRIDGE PIERS ON THE LEFT DESCENDING (LD) AND RIGHT DESCENDING (RD) SIDES OF A NAVIGABLE CHANNEL SHOW 180 DEGREE FIXED RED LIGHTS ON BOTH THE DOWNSTREAM (D/S) AND UPSTREAM (U/S) ENDS OF THE PIER. THIS LIGHT IS CALLED A:

– "PIER LIGHT"

• WHERE THE NAVIGABLE CHANNEL (MAIN CHANNEL OR ALTERNATE CHANNEL) IS LOCATED BETWEEN BRIDGE PIERS BUT DOES NOT EXTEND ALL THE WAY TO A BRIDGE PIER, THEN THE EXTENT OF THE CHANNEL IS MARKED BY 180 DEGREE FIXED RED LIGHTS LOCATED ON THE BRIDGE SPAN ON BOTH THE DOWNSTREAM (D/S) AND UPSTREAM (U/S) SIDES OF THE SPAN. THIS LIGHT IS CALLED A:

– "CHANNEL MARGIN LIGHT"




BRIDGE LIGHTING TYPES "A" -- MAIN OR ALTERNATE CHANNEL CENTER LIGHT (360 DEGREES GREEN)"B" -- PIER LIGHT (180 DEGREES RED)"C" -- CHANNEL MARGIN LIGHT (180 DEGREES RED)"D" -- MAIN CHANNEL LIGHTS (THREE VERTICAL LIGHTS, 180 DEGREES WHITE)

LOCATION MUST BE SPECIFIED:"LD" (LEFT DESCENDING) OR "RD" (RIGHT DESCENDING) FOR MARGIN AND PIER LIGHTS"U/S" (AS VIEWED FROM UPSTREAM) OR "D/S" (AS VIEWED FROM DOWNSTREAM)"MAIN" OR "ALTERNATE" CHANNEL


TYPICAL FIXED BRIDGE LIGHTING


(EXAMPLE: AS VIEWED FROM UPSTREAM)

MINIMUM LIGHTING FOR FIXED BRIDGES


BRIDGES MAY ALSO EXHIBIT AIRCRAFT CLEARANCE LIGHTS REQUIRED BY THE FAA.DISCREPANCIES SHOULD BE REPORTED TO THE NEAREST FAA FACILITY, NOT ON THE CG BRIDGE REPORT.


HOW WOULD EACH LIGHT BE DESIGNATED WHEN VIEWING FROM DOWNSTREAM?

HOW WOULD EACH LIGHT BE DESIGNATED WHEN VIEWING FROM DOWNSTREAM?

MINIMUM LIGHTING FOR FIXED BRIDGESMAIN AND ALTERNATE CHANNELS



LIGHTING FOR VERTICAL LIFT BRIDGES


• WHEN THE BRIDGE IS IN ANY POSITION OTHER THAN FULLY RAISED, THE CENTER OF THE LIFT BRIDGE SPAN IS MARKED BY TWO 180 DEGREE FIXED RED LIGHTS -- ONE FACING UPSTREAM AND THE OTHER DOWNSTREAM. WHEN FULLY RAISED, THE CENTER OF THE SPAN SHOWS TWO 360 DEGREE FIXED GREEN LIGHTS. EACH OF THESE RED AND GREEN LIGHTS IS CALLED A:

– "RED LIFT SPAN LIGHT" or "GREEN LIFT SPAN LIGHT" (identified on the graphic below as "A")

• EACH LIFT PIER, OR AN ATTACHED PROTECTION PIER, IS MARKED BY A 180 DEGREE FIXED RED LIGHT ON BOTH THE DOWNSTREAM (D/S) AND UPSTREAM (U/S) ENDS OF THE PIER. THIS LIGHT IS CALLED A:

– "LIFT PIER LIGHT" or "PIER LIGHT" (identified on the graphic below as "B")


LIGHTING FOR VERTICAL LIFT BRIDGES (Continued)


• A THIRD PIER LIGHT, IN ADDITION TO THE TWO (U/S AND D/S) PIER LIGHTS, MAY BE REQUIRED IF THE LIFT AND PROTECTION PIERS ARE NOT STRAIGHT ON THEIR CHANNEL FACES. THIS LIGHT IS A 180 DEGREE FIXED RED LIGHT MOUNTED IN THE MIDDLE OF THE BRIDGE PIER IN LINE WITH THE BRIDGE AXIS. THIS LIGHT IS CALLED AN:

– "AXIS LIGHT" (identified on the graphic below as "C")


MINIMUM LIGHTING FOR VERTICAL LIFT BRIDGES



NOTE: SOME LIFT BRIDGES, ESPECIALLY THOSE IN AUTOMATIC OR SEMIAUTOMATIC OPERATION, MAY SHOW ADDITIONAL LIGHTS IN BOTH THE U/S DIRECTION AND THE D/S DIRECTION. THESE ARE AUTHORIZED ON A CASE BY CASE BASIS. IN SOME CASES, COAST GUARD LIGHT LISTS AND NEWER CORPS OF ENGINEER CHARTS INCLUDE DESCRIPTIONS AND USAGE OF SPECIAL BRIDGE LIGHTING.


PIER LIGHTING FOR DOUBLE-OPENING SWING SPAN BRIDGES


• BRIDGE PIERS AT EITHER END OF THE MOVEABLE BRIDGE SPAN ARE CALLED "DRAW PIERS". EACH DRAW PIER, OR AN ATTACHED PROTECTION PIER IS MARKED BY A 180 DEGREE FIXED RED LIGHT ON BOTH THE DOWNSTREAM (D/S) AND UPSTREAM (U/S) ENDS OF THE PIER. THIS LIGHT IS CALLED A:

– "DRAW PIER LIGHT" or "PIER LIGHT"

• THE BRIDGE PIER IN THE CENTER ON WHICH THE MOVEABLE SPAN SITS IS CALLED THE "PIVOT PIER". THE PIVOT PIER, OR AN ATTACHED PROTECTION PIER IS MARKED BY A 180 DEGREE FIXED RED LIGHT ON BOTH THE DOWNSTREAM (D/S) AND UPSTREAM (U/S) ENDS OF THE PIER. THIS LIGHT IS CALLED A:

– "PIVOT PIER LIGHT"

• A THIRD PIER LIGHT, IN ADDITION TO THE TWO (U/S AND D/S) DRAW OR PIVOT PIER LIGHTS, MAY BE REQUIRED IF THE DRAW OR PIVOT PIERS AND ATTACHED PROTECTION PIERS ARE NOT STRAIGHT ON THEIR CHANNEL FACES. THIS LIGHT IS A 180 DEGREE FIXED RED LIGHT MOUNTED IN THE MIDDLE OF THE APPLICABLE DRAW OR PIVOT PIER IN LINE WITH THE BRIDGE AXIS. THIS LIGHT IS CALLED AN:

– "AXIS LIGHT"


SPAN LIGHTING FOR DOUBLE-OPENING SWING SPAN BRIDGES


• THREE LIGHT FIXTURES, EACH CONSISTING OF TWO 60 DEGREE RED LIGHTS AND TWO 60 DEGREE GREEN LIGHTS (SEE DIAGRAM BELOW SHOWING SPAN IN CLOSED POSITION), ARE LOCATED ATOP THE BRIDGE SPAN AT EITHER END AND AT THE CENTER POINT.

• EACH LENS IN A FIXTURE IS LOCATED AT 90 DEGREES FROM ITS ADJACENT LENS AND SHOWS THROUGH AN ARC OF 60 DEGREES. WHEN ONLY THE GREEN LENS ARE SHOWING DIRECTLY UPSTREAM AND DOWNSTREAM FROM THESE FIXTURES, THEN THE BRIDGE WOULD BE IN THE FULLY OPEN POSITION. THIS LIGHT FIXTURE IS CALLED A:

– "SWING SPAN LIGHT"


MINIMUM LIGHTING FOR DOUBLE-OPENING SWING SPAN BRIDGES



NOTE: IN ORDER TO PROPERLY IDENTIFY ANY GREEN SWING SPAN LIGHT DISCREPANCIES ON A CLOSED BRIDGE (OR RED SWING SPAN LIGHT DISCREPANCIES ON AN OPEN BRIDGE), IT WOULD BE NECESSARY TO VISUALLY DETERMINE WHICH DIRECTION THE BRIDGE OPENS (OR CLOSES). HOWEVER, NEVER REQUEST A BRIDGE TO OPEN (OR CLOSE) IF ONLY TO VERIFY BRIDGE LIGHTING.


LIGHTING FOR DOUBLE-LEAF BASCULE BRIDGES


• EACH BASCULE BRIDGE PIER IS MARKED BY A 180 DEGREE FIXED RED LIGHT ON BOTH THE DOWNSTREAM (D/S) AND UPSTREAM (U/S) ENDS OF THE PIER. THIS LIGHT IS CALLED A:

– "DRAW PIER LIGHT" or "PIER LIGHT"

• WHEN A THE BRIDGE IS IN ANY POSITION OTHER THAN FULLY RAISED., THE CENTER OF THE BRIDGE SPAN IS MARKED BY TWO 180 DEGREE FIXED RED LIGHTS (ONE ON EACH LEAF SPAN) ON BOTH THE UPSTREAM SIDE AND ON THE DOWNSTREAM SIDE. WHEN FULLY RAISED, THESE LIGHTS SHOW 180 DEGREE FIXED GREEN LIGHTS. EACH OF THESE IS CALLED A:

– "RED LEAF SPAN LIGHT" or "GREEN LEAF SPAN LIGHT"

• A THIRD PIER LIGHT, IN ADDITION TO THE TWO (U/S AND D/S) DRAW PIER LIGHTS, MAY BE REQUIRED IF THE DRAW PIERS AND ATTACHED PROTECTION PIERS ARE NOT STRAIGHT ON THEIR CHANNEL FACES. THIS LIGHT IS A 180 DEGREE FIXED RED LIGHT MOUNTED IN THE MIDDLE OF THE APPLICABLE DRAW PIER IN LINE WITH THE BRIDGE AXIS. THIS LIGHT IS CALLED AN:

– "AXIS LIGHT"


MINIMUM LIGHTING FOR DOUBLE-LEAF BASCULE BRIDGES





BRIDGE LATITUDE / LONGITUDE (LAT/LONG) POSITION DATA USING GPS

• FOR FACILITIES THAT HAVE A GPS / DGPS CAPABILITY, AID VERIFIERS ARE ASKED TO:

–VERIFY LAT. / LONG. POSITION DATA THAT IS SHOWN ON THE BRIDGE REPORT WORKSHEET, OR

–PROVIDE LAT. / LONG. DATA IF NOT SHOWN ON WORKSHEET

• A BRIDGE LOCATION IS DEFINED BY THE EXTENT OF THE MAIN CHANNEL WHICH MAY BE MARKED BY EITHER A MAIN CHANNEL PIER LIGHT OR A MAIN CHANNEL MARGIN LIGHT. THE BRIDGE REPORT WORKSHEET ASKS FOR THE LAT. / LONG. COORDINATES FOR BOTH:

THE LEFT DESCENDING MAIN CHANNEL PIER (OR CHANNEL MARGIN), AND

THE RIGHT DESCENDING MAIN CHANNEL PIER (OR CHANNEL MARGIN)

AS VIEWED ON THE DOWNSTREAM SIDE OF THE BRIDGE.



BRIDGE LATITUDE / LONGITUDE (LAT/LONG) POSITION DATA USING GPS

• LAT. / LONG. DATA CAN BE SPECIFIED TWO WAYS:

IN DEGREES, MINUTES AND THOUSANDTHS OF MINUTES, OR

IN DEGREES, MINUTES, SECONDS AND HUNDREDTHS OF SECONDS (WHICH IS THE WAY THE DATA IS SHOWN ON THE BRIDGE REPORT WORKSHEETS)

• ALWAYS USE DECIMAL POINTS WHEN RECORDING THE DATA. DASHES OR SPACES MAY BE USED TO SEPARATE DEGREES, MINUTES AND SECONDS. THE FOLLOWING WOULD BE VALID ENTRIES FOR THE SAME POSITION:

45-81.520

45 81.520

45-81-31.20

45 81 31.20



BRIDGE REPORT WORKSHEET(TOP OF FORM)

TOP OF BRIDGE REPORT WORKSHEET• SHOWS INFORMATION OF RECORD BASED ON:

LIGHT LIST DATA DATA PREVIOUSLY REPORTED BY AID VERIFIER

• AID VERIFIER ENTERS: TIME(S) AND DATE(S) OF ACTUAL VERIFICATION(S) GPS POSITION DATA (VERIFY IF SHOWN, ENTER IF NOT SHOWN)



BRIDGE REPORT WORKSHEET(MIDDLE OF FORM)

NOTES:• ANSWER CLEARANCE GAUGE QUESTION – IF "NO” FOLLOW INSTRUCTIONS ON RIGHT

• FOR ANY DISCREPANCIES, SUCH AS BAD LAMPS, DAMAGED PROTECTION FENDERS / CELLS, UNREADABLE CLEARANCE GAUGES, ENTER SPECIFIC DISCREPANCIES IN LOWER SECTION USING PROPER LOCATION NOMENCLATURE (U/S, D/S, PIER, CENTER, CHANNEL, etc.)

• FOR LIGHT DISCREPANCIES, INDICATE WHETHER RED SQUARE (OR DIAMOND) REFLECTORS ARE SHOWING NEAR THE LIGHT(S)



BRIDGE REPORT WORKSHEET(BOTTOM OF FORM)

NOTES:• CHECK "( ) WATCHING PROPERLY" ONLY IF EVERYTHING IS SHOWING PROPERLY

• IF DISCREPANCIES WERE REPORTED VIA RADIO OR PHONE TO GROUP, MAKE ENTRY UNDER SECTION "CRIT. / URG. DISC. REPORTED VIA". (SEE PREVIOUS CHART.)

• ENTER AID VERIFIER IDENTIFICATION (QUALIFIED AID VERIFIERS ONLY) AT BOTTOM.




• FOR EACH DISCREPANT LIGHT, REPORT THE – "AS VIEWED FROM" DIRECTION -- "U/S" (Upstream) or "D/S" (Downstream)

– POSITION RELATIVE TO THE CHANNEL -- "Center", "LD" (Left Descending) or "RD" (Right Descending)

– LENS COLOR -- "RED", "GREEN", or " WHITE"

– CHANNEL -- "CHANNEL" (No Alternate Channel), "MAIN CHANNEL" (If Alternate Channel), "ALTERNATE CHANNEL"

– TYPE / LOCATION -- "PIER LIGHT", "PIVOT PIER LIGHT", "SPAN LIGHT", "AXIS LIGHT", "CHANNEL CENTER LIGHT", or "CHANNEL MARGIN LIGHT"

– DISCREPANCY -- "EXTINGUISHED", "DIM", "OUT OF FOCUS", etc.

• EXAMPLES:– U/S LD RED MAIN CHANNEL PIER LIGHT

– D/S RED PIVOT PIER LIGHT

– U/S GREEN ALTERNATE CHANNEL CENTER LIGHT

ALL EXTINGUISHED LIGHTS AND ANY OTHER DISCREPANCY THAT WOULD BE CONSIDERED A HAZARD TO NAVIGATION SHOULD BE REPORTED IMMEDIATELY VIA MARINE RADIO TO THE APPROPRIATE GROUP.




• FOR EXTINGUISHED LIGHTS, ALSO INDICATE:– IF THE LIGHT FIXTURE IS VISIBLE

– IF THERE IS A RED REFLECTIVE SQUARE OR DIAMOND LOCATED IN PROXIMITY TO THE LOCATION YOU WOULD EXPECT TO FIND A LIGHT

• REPORT ANY DAMAGE TO BRIDGE PROTECTION CELLS AND FENDERS: – IDENTIFYING THE LOCATION AS YOU WOULD A LIGHT

• REPORT THE READABILITY OF CLEARANCE GAUGES:– "READABLE"– "NOT READABLE" (SPECIFY PIER LOCATION -- D/S or U/S, LD or RD)– "NO GAUGES"

ALL EXTINGUISHED LIGHTS AND ANY OTHER DISCREPANCY THAT WOULD BE CONSIDERED A HAZARD TO NAVIGATION SHOULD BE REPORTED IMMEDIATELY VIA MARINE RADIO TO THE APPROPRIATE GROUP.
