The Double-Line Overhead Street Name Sign (D3-5) may be mounted overhead at signalized intersections to identify the name of the cross road where each leg of the cross road has a different street name. Abbreviations follows the street name text may be displayed when determined to be applicable or needed. Messages should conform with the Department's "Name Usage and Abbreviation Guide for Street Name Signs" (see Appendix).
Standard colors shall be white legend and border on a green background, but white-on-blue, white-on-brown, or black-on-white colors may be used if used systematically throughout the municipality.
The D3-5 sign may vary in width as necessary to accommodate the required legend. The legend should be Standard Alphabet Series B, C, or D, of the highest series possible. The standard size lettering is 12-inch uppercase and 9-inch lowercase. For long street names where the legend would otherwise exceed the maximum width which can be structurally or physically accommodated, the spacing between characters may be compressed up to 35 percent, as necessary. If a sign using the standard size lettering is still too large, this will serve as engineering justification for using smaller size lettering. The smallest size sign may only be used on traffic signal approaches with a 25 mph speed limit.
Although a standard sign blank is not specified, 0.08" aluminum should be used.
Enter information in the boxes within the Sign Inputs section. The sign will automatically update when the cursor moves outside the sign legend box or other items are selected from the drop-down menus. Use < and > for arrows.
The maximum sign width for standard traffic signal structures is 96 inches per Publication 148 and Publication 149. If the resulting sign width is more than 96 inches, the sign width will appear in red text. Signs greater than 96 inches in width require a special structural analysis to be used on traffic signal supports.
The slider bar for the spacing ratio ranges from 65% of normal spacing (35% reduction) on the left to 100% (no reduction) on the right.
This calculator will automatically center text vertically. The top (C) and bottom (F) margins in Pub 236 are used for text with descenders. Equal margins are used if there are no descenders.
This calculator provides sign widths in 6-inch increments.
