630.03 Certified Drawings. Furnish
certified drawings according to 625.06.
Submit sign support certified drawings that cover all design types such as
ground mounted, rigid overhead, span wire mounted, and overpass structure
mounted supports. On the drawings, show overall height, sign clearance
above foundation, span length, sign locations, sign overall heights and widths,
and glare shield height and location, if applicable.
630.04
Sign
Fabrication.
Sign types include flat sheet, double faced, extrusheet,
and temporary overlay. Flat sheet signs consist of one-piece units made
of aluminum. Double faced signs consist of flat sheet aluminum or
extruded aluminum blanks with legend on both sides. Extrusheet
signs consist of a number of horizontal panels assembled to form a complete
sign. Temporary overlay signs consist of an aluminum sheet covering
portions or entire surfaces of extrusheet signs.
Prior
to reflective sheeting application, clean aluminum sign surfaces either by
total immersion in a tank containing an alkaline solution of the manufacturer’s
specification or by steam cleaning with an alkaline solution of the
manufacturer’s specification, followed by a thorough rinsing with running
water. After cleaning, etch the surface with an acid solution, and
dry. Do not allow cleaned and etched surfaces to become contaminated by contact
with oil or grease. Drill or punch bolt holes to finish size.
Use
sign legends according to the OMUTCD and the Sign
Designs and Markings Manual. Use Clearview
font for positive contrast legends on freeway and expressway guide signs and on
all other guide signs when permitted in the Sign
Designs and Markings Manual. For negative contrast legends, use the
Standard Alphabets for Traffic Control Devices. Use capital legends and
upper/lower case legends in accordance with the Sign
Designs and Markings Manual. When either is permitted in the Sign
Designs and Markings Manual, use upper/lower case legends.
For
flat sheet, double faced mile marker, double faced street name and ground
mounted extrusheet signs, use Type G, H or J
reflective sheeting for background and reflective legends. For overhead extrusheet signs, use Type G, H or J reflective sheeting
for the background, and use Type H or J reflective sheeting for reflective
legends, shields and symbols (including hazardous material plaque, airport
symbol, arrows and borders). Apply reflective sheeting to the surface according
to the manufacturer’s recommendations, with no blisters, wrinkles, tears, or
blemishes. Do not use reboundable or damage
control sheeting for permanent signs.
For
reflective legends on flat sheet, double faced mile marker and double faced
street name signs, use reverse silk screen transparent ink, transparent acrylic
electronic cuttable film, or direct applied
reflective sheeting copy. When using direct applied reflective sheeting
copy, apply all legend on a sign with the same rotation angle
orientation. For nonreflective legends, use
direct silk screen black ink or direct applied nonreflective
acrylic opaque black sheeting copy. For double faced mile marker signs,
use flat sheet aluminum and apply reflective sheeting and legend to both
sides. For double faced street name signs, use extruded
aluminum blanks with a minimum thickness of 0.063 inch (1.6 mm) and
thicker, stiffened edges, and apply reflective sheeting and legend to
both sides.
Extrusheet panels consist
of flat sheet aluminum reinforced with aluminum extrusions attached by spot
welding. Panels extruded in a single operation may be used in lieu of
spot welded panels. Do not use extruded
panels and spot welded panels in the same sign. Bolt together the
minimum number of full length, sheeted panels to achieve the sign height, using
aluminum bolts, washers, lock washers and nuts. For reflective legends,
shields and symbols (including hazardous material plaque, airport symbol,
arrows and borders) use direct applied reflective sheeting. Apply all
reflective legend on a sign with the same rotation angle orientation. For
nonreflective legends, use direct applied nonreflective acrylic opaque black sheeting
copy.
For
temporary overlay signs, use 0.080-inch (2.0 mm) thick flat sheet aluminum,
with a maximum panel size of 8 x 4 feet (2.4 x 1.2 m). Apply
sheeting and legend as described above for extrusheet
signs. Attach temporary overlays to extrusheet
signs in the shop or field using aluminum blind rivets at a maximum spacing of
18 inches (0.5 m) on the peripheries of the temporary overlays and 24 inches
(0.6 m) within the interior.
Use
fluorescent yellow-green reflective sheeting for the following signs and
plaques: School (S1-1), School Bus Stop Ahead (S3-1), SCHOOL BUS TURN AHEAD
(S3-2), SCHOOL ENTRANCE (S3-H3), SCHOOL (S4-3P), School Speed Limit Ahead
(S4-5, S4-5a), yellow portions of School Speed Limit (S5-H1), Pedestrian
Crossing (R1-6, R1-6b, R1-9), Bicycle (W11-1), Pedestrian (W11-2), Handicapped
(W11-9), Bicycle/Pedestrian (W11-15), Trail Crossing (W11-15a), Playground
(W15-1), and SAFETY ZONE (W15-H2). Fabricate supplemental warning plaques
[such as Advisory Speed (W13-1P), SHARE THE ROAD (W16-1P), Distance (W16-2P,
W16-2aP, W16-3P, W16-3aP), Supplemental Arrow (W16-5P,
W16-6P, W16-7P) and AHEAD (W16-9P)] from fluorescent yellow-green reflective
sheeting when used with a sign above.
Use
fluorescent yellow reflective sheeting for all yellow signs, yellow portions of
multi-colored signs, and yellow sign post reflectors, except for signs and
portions of signs required to be fabricated with fluorescent yellow-green
reflective sheeting.
For
lighted signs, cover glare shield and rectangular luminaire support tube with nonreflective acrylic sheeting matching the predominant
sign color.
Furnish
4 x 2.5 inch (100 x 62 mm) sign identification stickers of Type F reflective
sheeting as shown in Figure 1. For signs fabricated in English based
sizes, use white stickers with red ink legend. For signs fabricated in
hard metric based sizes, regardless of the sign message units contained on the
sign face, use yellow stickers with red ink legend. Place the stickers on
the back side of the sign in the lower right corner of rectangular signs, or in
an equivalent location for other sign shapes, approximately 3 inches (75 mm)
from side and bottom sign edges (for smaller signs, these dimensions may be
reduced). Position the sticker so it can be read horizontally and is
clearly visible, not near bolt holes or rivets, and not obstructed by the sign
support when erected.
Silk
screen the fabrication data onto the face of the sticker, and include the
sheeting manufacturer identification code and year of fabrication.
Alternatively, the numbers 0-1-2-3-4-5-6-7 and 13-14-15-16-17 may be silk
screened onto the sticker with the correct sheeting manufacturer identification
code and fabrication year punched out, respectively. At the time of sign
erection, indicate the erection data by scratching out the appropriate month
and year.

the bottom of the signs are in a level position,
regardless of bridge slope.
E. Sign Attachments. Use sign attachment assemblies to attach extrusheet signs to rigid overhead supports. Use sign
hanger assemblies to attach flat sheet signs to span wire or rigid overhead
supports. Use sign support assemblies to attach flat sheet or extrusheet signs to poles or bridge parapets. Use
sign backing assemblies for groups of signs attached to a sign post, and to
attach exit number or supplemental panels to an extrusheet
sign.
630.07 Sign Erection. Erect signs on ground
mounted or overhead supports according to the schematic signing layout.
Mount overhead signs so that the bottom of the signs are in a level position
regardless of the sag of supporting messenger wire, mast arm rise, chord member
or overpass slope. Do not remove an existing sign until the replacement
sign is either erected or available for immediate erection. Do not erect
a replacement sign on a new support more than 24 hours before the removal of
the existing sign.
Use steel bolts, wide
washers, lock washers and nuts. Use bearing plates
between the sign and U-channel post at each bolt. Field drill
signs mounted on messenger wire or mast arms to match holes in brackets.
Use self-aligning
aluminum mounting clips, aluminum or stainless steel rectangular head bolts,
aluminum or stainless steel washers, and stainless steel elastic stop nuts, to
attach extrusheet signs to beam or U-channel post
supports, and for U-channel post sections used to attach exit number and
