Fabrication of Highways Signs Policy 2.1.25.pdf

FABRICATION OF HIGHWAY SIGNS POLICY

Effective February 1, 2025

REVISIONS FROM PREVIOUS EDITION

Replaced AZ sheeting with ZZ sheeting for all signs using fluorescent yellow or fluorescent yellow-green.

To allow contractors time to refurbish new fluorescent yellow and fluorescent yellow-green signs in accordance with this policy, existing stock of these signs utilizing AZ sheeting may be used for contracts let prior to February 1, 2025.

INTRODUCTION

Roadway signs are the major traffic control device the department uses along its roadways to communicate to motorists. In order to provide this important information, and as a result of the improvements and cost reductions of prismatic retroreflective sign sheeting materials, the Central Bureau of Operations has updated the department’s retroreflective sign sheeting policy.

This policy only applies to highways under the jurisdiction of the State of Illinois and to local agency projects that include the use of the IDOT Standard Specifications for Road and Bridge Construction. Local agencies may determine what sign sheeting material is appropriate as long as it conforms to the minimum retroreflectivity requirements in the national Manual on Uniform Traffic Control Devices (MUTCD) for projects that do not involve the Standard Specifications for Road and Bridge Construction.

For internal IDOT sign fabrication, there will be no specific compliance date established for this policy.

Signs currently installed which do not meet this policy should be upgraded as the replacement program permits. Any MUTCD compliance dates would supersede this guidance.

This policy in accordance with the Standard Specifications for Road and Bridge Construction shall be used for sign fabrication of all work zone signs.

SIGN SHEETING TYPES

The department will now utilize three types of sign sheeting. Type AA sheeting will be used for fluorescent orange work zone signs. Type AA sheeting is typically defined as a prismatic sheeting that has good reflectivity values when rotated at 45 degrees. Type AP sheeting will be used for almost all standard traffic signs except those fabricated using fluorescent yellow or fluorescent yellow-green. Type AP sheeting is typically defined as a high intensity cube-cornered prismatic sheeting used as a good all-purpose traffic sign sheeting. Type ZZ sheeting will be used for some freeway guide signs, overhead sign installations, fluorescent yellow/fluorescent yellow-green signs, and some regulatory signs. Type ZZ sheeting is typically defined as an extremely high intensity sheeting that provides good retroreflectivity values at both long and short distances as well as with high observation angles.

As a result of the significant increase in retroreflectivity of Type ZZ sheeting, the lighting on overhead sign trusses is not required. Lighting equipment should not be installed on new overhead sign structures unless through engineering judgment specific circumstances indicate that appropriate visibility will not be obtained. As signs are upgraded on existing overhead sign structures, the sign lighting should be turned off, but the fixtures do not have to be removed. The lighting fixtures should be removed the next time

Illinois Department of Transportation Bureau of Operations

Fabrication of Highway Signs Policy February 1, 2025 the structure is repaired or replaced. Walkways for overhead sign structures should remain in place for future sign maintenance purposes.

STANDARD HIGHWAY SIGNS LIST

The Standard Highway Signs List in this policy contains most of the standard highway signs as prescribed in the 2009 edition of the Illinois Manual on Uniform Traffic Control Devices. This list consists of national standard highway signs and additional signs prepared by the Illinois Department of Transportation indicated as Illinois Standards. The list also includes the appropriate sheeting type to use for each specific sign and the section of the MUTCD which contains more information about the sign, if applicable.

The detailed drawings of the national standard highway signs are available in the Standard Highway Signs Book on the internet at: http://mutcd.fhwa.dot.gov. The detailed drawings for Illinois standard signs are available in the Illinois Standard Highway Signs Book on the internet at: http://www.idot.illinois.gov.

FONT REQUIREMENTS

(E) Modified font is to be used for freeway and expressway signs. While IDOT had previously used Clearview font for these signs, and FHWA has reinstated the Interim Approval for use of Clearview font, IDOT will continue to use (E) Modified font for freeway and expressway signs. Standard highway fonts for all other signs will remain in accordance with the FHWA Standard Highway Signs Manual and the Illinois Standard Highway Signs Book.

STANDARD HIGHWAY SIGNS LIST

PREFACE

This list is intended for use by personnel involved with the fabrication, installation, and maintenance of traffic signs on state-maintained highways and contracts utilizing the IDOT Standard Specifications for Road and Bridge Construction. This list has many typical standard signs approved for use on streets and highways. All symbols shall be unmistakably similar to those shown in the Standard Highway Signs Book. Where a word message is applicable; the wording shall be as shown in the Standard Highway Signs Book unless alternate wording is optional. Most standard symbols are oriented facing left;

however, this does not preclude the use of mirror images of these symbols where the reverse orientation might better convey to vehicle operators a direction of movement. Standardization of these designs does not preclude further improvement by minor changes in the width of borders or layout of word messages, but all shapes and colors shall be as indicated. Any of the warning signs may be made in black and orange, in lieu of black and yellow, when used in work zones. Signs should be sized according to the MUTCD or Illinois Standard Highway Sign Book.

There are certain supplemental plaques, like those used in conjunction with signing hazardous conditions, which signify the kind of hazard that may be encountered or the name of an intersecting highway. The messages carried by these plaques supplement the main sign and should, therefore, remain permanently with the main sign. Another use of permanent supplemental plaques would be the “$250 Fine” plaque below the “Handicap Parking” sign; or the “All Way” plaque below a “Stop” sign where the supplemental plaques specifically describe the situation. Any route shield auxiliary panels should be made in the same color as the shields where they apply.

This listing may contain signs not routinely used in Illinois. The inclusion of such signs does not constitute a revision to the Illinois Manual on Uniform Traffic Control Devices or IDOT Policy.

This listing may contain signs for conventional highways or expressways that may not be appropriate for the respective facility. The appropriateness of any particular sign should be determined by review of the MUTCD, Illinois Manual on Uniform Traffic Control Devices, or IDOT Policy.
