2 NOTES: 1. THE DESIGN OF THIS STRUTURE IS BASED ON THE AASHTO STANDARD SEIFIATIONS FOR STRUTURAL SUORTS FOR HIGHWAY SIGNS, LUMINARIES AND TRAFFI SIGNALS, URRENT EDITION. 2. WELDING MUST BE IN ONFORMANE WITH AMERIAN WELDING SOIETY (AWS) D1.1:2010, STRUTURAL WELDING ODE-STEEL (AS MODIFIED BY THE URRENT 12S-707A - STRUTURAL STEEL AND ALUMINUM ONSTRUTION), HEREAFTER ALLED AWS D MAXIMUM SIGN AREA IS 1200 SQUARE FEET. SIGNS MUST NOT ROJET AST THE ENDS OF THE TRUSS. MAXIMUM 6 FOOT SIGN ROJETION ABOVE THE TO HORD. 4. FOR TRUSS LENGTHS 50 FEET TO 105 FEET, MINIMUM SIGN HIEIGHT WITH ALUMINUM BEAM IS 7 FEET. FOR TRUSS LENGTHS 110 FEET TO 140 FEET, MINIMUM SIGN HEIGHT WITH ALUMINUM BEAM IS 9 FEET. 5. TYE I SIGNS MUST NOT BE USED ON THE SAME TRUSS AS VARIABLE MESSAGE SIGNS. 6. HOT-DI GALVANIZE (HDG) ALL TRUSS OMONENTS ER ASTM A123 RIOR TO BOLTED ASSEMBLY. HDG ALL FASTENER OMONENTS ER ASTM A153. BLAST LEAN BASE LATES, STIFFENERS, AND ALL WELDMENTS RIOR TO GALVANIZING. 7. ROVIDE 15/1 OHOLES FOR 7/8" HIGH O STRENGTH (HS) BOLTS FOR ALL ONNETIONS UNLESS OTHERWISE STATED. ROVIDE HIGH STRENGTH BOLTS, NUTS, AND WASHERS IN AORDANE WITH SUBSETION OF THE MDOT STANDARD SEIFIATIONS FOR ONSTRUTION. ROVIDE LOK WASHERS THAT MEET ANSI B TIGHTEN ALL HIGH STRENGTH (HS) BOLTS BY THE TURN OF NUT METHOD ER SUBSETION D OF THE MDOT STANDARD SEIFIATIONS FOR ONSTRUTION, EXET AT SLIE ONNETIONS. SLIE ONNETIONS MUST HAVE A FLAT WASHER AND LOK WASHER UNDER EAH NUT AND TIGHTENED TO A SNUG TIGHT ONDITION ER SUBSETION D OF THE MDOT STANDARD SEFIATIONS FOR ONSTRUTION. 9. DO NOT LIFT THE TRUSS BY THE WEB MEMBERS. 10. FIELD SLIES MAY BE LAED ALONG THE TO FAILITATE FABRIATION. LAE FIELD SLIE 1'- MINIMUM TO THE GUSSET LATE EDGE. ANY DEVIATION FROM THE DETAILS SHOWN ON THIS TYIAL WILL REQUIRE AROVAL BY THE ENGINEER IN WRITING BEFORE FABRIATION. 11. ALL WELDS MUST BE 100 ERENT VISUAL TEST (VT) INSETED BY AN AWS ERTIFIED WELDING INSETOR (WI). ALL FILLET WELDS (EXET END A AND OLUMN A WELDS) MUST BE 25 ERENT MAGNETI ARTILE TEST (MT) INSETED BY A TEHNIIAN QUALIFIED IN AORDANE WITH AMERIAN SOIETY OF NONDESTRUTIVE TESTING (ASNT) LEVEL II. ALL OMLETE JOINT ENETRATION (J) WELDS MUST BE 100 ERENT ULTRASONI TEST (UT) INSETED BY A TEHNIIAN QUALIFIED IN AORDANE WITH ASNT LEVEL II. 12. SEE URRENT MDOT SIGN SUORT TYIAL LAN SIGN-340-SERIES FOR SIGN FOUNDATION. 13. SEE URRENT MDOT SIGN SUORT TYIAL LAN SIGN-700-SERIES FOR SIGN ONNETION. 14. OLUMN SETIONS MUST BE ASTM A53, GRADE B OR AI-5L-X42. SETIONS FOR 50 FEET TO 105 FEET TRUSSES MUST BE 24" O X 0.938" OR 24" O X 0.969". SETIONS FOR 110 FEET TO 140 FEET TRUSSES MUST BE 24" O X 1.219". HORD SETIONS MUST BE ASTM A500, GRADE B O X 0.500", ASTM A ANNEALED O X 0.375" OR ASTM A500, GRADE B 6 5/8" O X 0.432". 15. WEB ANGLES MUST BE ASTM A709, GRADE 36 OR ASTM A36 L5" X 5" X 7/1 OR L5" X 5" X 1/2". STEEL LATES MUST BE ASTM A709, GRADE 36 OR ASTM A 36 STEEL. 16. THE ESTIMATED WEIGHT OF THE TRUSS IS 195 LBS/FT. 17. DURING THE ERETION ROESS THE MINIMUM NUMBER OF BOLTS REQUIRED TO BE INSTALLED RIOR TO LETTING TRAFFI RESUME UNDER THE ERETED TRUSS MUST BE: 2 BOLTS MINIMUM ER HORD-OLUMN ONNETION LATE FOR SAN LENGTHS BETWEEN 50' AND 105', AND 4 BOLTS MINIMUM ER HORD-OLUMN ONNETION LATE FOR SAN LENGTHS BETWEEN 110' AND 140'. NO SIGNS SHALL BE ERETED UNTIL ALL BOLTS ARE INSTALLED. 18. BASE LATE ( ) WARAGE MUST NOT EXEED 1/16 INH ER FOOT. 19. BAKING BAR FOR OTIONAL OLUMN SLIE MUST BE MINIMUM INH X 2 INH LATE OR STANDARD HILL RING. BAKING BAR FOR OLUMN TO BASE LATE MUST BE MINIMUM INH X 1 INH LATE OR STANDARD HILL RING.
