As a lane drop marking in advance of lane drops at exit ramps to distinguish a lane drop from a normal exit ramp (see Drawings A, B, and C of, In advance of freeway route splits with dedicated lanes (see Drawing D of, To separate a through lane that continues beyond an interchange from an adjacent auxiliary lane between an entrance ramp and an exit ramp (see Drawing E of, As a lane drop marking in advance of lane drops at intersections to distinguish a lane drop from an intersection through lane (see Drawing A of, To separate a through lane that continues beyond an intersection from an adjacent auxiliary lane between two intersections (see Drawing B of. 06 Since yellow and white curb markings are frequently used for curb delineation and visibility, it is advisable to establish parking regulations through the installation of standard signs (see Sections 2B.46 through 2B.48). 03 Where highway design or reduced visibility conditions make it desirable to provide control or to guide vehicles through an intersection or interchange, such as at offset, skewed, complex, or multi-legged intersections, on curved roadways, where multiple turn lanes are used, or where offset left turn lanes might cause driver confusion, dotted line extension markings consisting of 2-foot line segments and 2- to 6-foot gaps should be used to extend longitudinal line markings through an intersection or interchange area. Examples of approach markings for obstructions in the roadway are shown in, If traffic is required to pass only to the right of the obstruction, the markings shall consist of a two-direction no-passing zone marking at least twice the length of the diagonal portion as determined by the appropriate taper formula (see Drawing A of, If traffic is required to pass only to the right of the obstruction, yellow diagonal crosshatch markings (see, If traffic can pass either to the right or left of the obstruction, the markings shall consist of two channelizing lines diverging from the lane line, one to each side of the obstruction. In addition, fog seals have proved to be incompatible with the thermoplastic material sometimes used for pavement markings. If authorized by law, Do Not Block Intersection markings with appropriate signs may also be used at other locations. Guidance: 20100XXX Tree Removal (PDF) Standard: Figure 3B-8 Examples of Dotted Line and Channelizing Line Applications for Exit Ramp Markings. 01 Pavement markings shall be used to guide traffic away from fixed obstructions within a paved roadway. 0 Other markings, such as white delineators, white channelizing devices, white raised pavement markers, and white crosswalk markings may also be placed in the flush median area. Speed measurement markings may extend 24 inches on either side of the center line or 24 inches on either side of edge line markings at 1/4-mile intervals over a 1-mile length of roadway. On narrow, low-speed shared-use paths, the pavement words, symbols, and arrows may be smaller than suggested, but to the relative scale. 02-2: Construction Projects Incorporating experimental

These markings shall be placed with the broken line toward the two-way left-turn lane and the solid line toward the adjacent traffic lane as shown in, White two-way left-turn lane-use arrows (see, Signs should be used in conjunction with the two-way left turn markings (see, If a continuous flush median island formed by pavement markings separating travel in opposite directions is used, two sets of solid double yellow lines shall be used to form the island as shown in. Center line pavement markings may be placed at a location that is not the geometric center of the roadway. Standard: Examples of parking space markings are shown in Figure 3B-21. 04 Speed reduction markings should not be greater than 12 inches in width, and should not extend more than 18 inches into the lane. 02 When center line markings are used, no-passing zone markings shall be used on two-way roadways at lane-reduction transitions (see Section 3B.09) and on approaches to obstructions that must be passed on the right (see Section 3B.10). Support: The color of raised pavement markers under both daylight and nighttime conditions shall conform to the color of the marking for which they serve as a positioning guide, or for which they supplement or substitute. 0 16 Stop and yield lines may be staggered longitudinally on a lane-by-lane basis (see Drawing D of Figure 3B-13). Standard: Option: The IDOT Construction Manual is compiled to clarify the IDOT Standard Specifications for Road and Bridge Construction and to suggest uniform procedures in highway construction field work. Option: 01/01/07 - all district one details have been modified to reflect idot 2007 spec 2. The drawing files below are the most current revisions. The "Americans with Disabilities Act Accessibility Guidelines for Buildings and Facilities (ADAAG)" (see Section 1A.11) contains specifications for design and placement of detectable warning surfaces. The manual is organized similar to the Standard Specifications. Guidance: The bidirectional marker is capable of displaying the applicable color for each direction of travel. 04 To improve the visibility of horizontal curves, center lines may be supplemented with retroreflective or internally illuminated raised pavement markers for the entire curved section as well as for a distance in advance of the curve that approximates 5 seconds of travel time. 04 When crosshatch markings are used on paved shoulders, they shall be diagonal markings that slant away from traffic in the adjacent travel lane. Please navigate to Consultant Resources to view Coded Pay Items. 09 Except as provided in Paragraph 3 for low-speed urban roadways, the edge line markings shown in Figure 3B-14 should be installed from the location of the Lane Ends warning sign to beyond the beginning of the narrower roadway. J}* H /99RUr! Support: The center line markings on undivided two-way roadways with four or more lanes for moving motor vehicle traffic always available shall be the two-direction no-passing zone markings consisting of a solid double yellow line as shown in, On two-way roadways with three through lanes for moving motor vehicle traffic, two lanes should be designated for traffic in one direction by using one- or two-direction no-passing zone markings as shown in. 17 The yield-ahead triangle symbol or YIELD AHEAD word pavement marking shall not be used unless a YIELD sign (see Section 2B.08) is in place at the intersection. Option: Lane line markings should also be used at congested locations where the roadway will accommodate more traffic lanes with lane line markings than without the markings. Because non-intersection pedestrian crossings are generally unexpected by the road user, warning signs (see. Where opposing offset channelized left-turn lanes exist, lane-use arrow markings should be placed near the downstream terminus of the offset left-turn lanes to reduce wrong-way movements (see. A through lane that becomes a mandatory exit or turn lane, An auxiliary lane 2 miles or less in length between an entrance ramp and an exit ramp, or. Section 11-307 of the "Uniform Vehicle Code (UVC)" contains further information regarding required road user behavior in no-passing zones. 22 Where lane changes might cause conflicts, a wide or normal solid white lane line may extend upstream from an intersection. To view the most current DGN files please navigate to Highways Standards. Section 4N.02 contains information regarding In-Roadway Warning Lights at crosswalks. Standard Specifications / Supplemental Specifications and Recurring Special Provisions are now located under Engineering, Architectural & Professional section under the Consultant Resources link. Rural arterials and collectors with a traveled way of 20 feet or more in width and an ADT of 3,000 vehicles per day or greater. Standard: Support: Where crossing the lane line markings is discouraged, the lane line markings shall consist of a normal or wide solid white line. Detectable warning surfaces are required by 49 CFR, Part 37 and by the Americans with Disabilities Act (ADA) where curb ramps are constructed at the junction of sidewalks and the roadway, for marked and unmarked crosswalks. (BC 57)" "105 Working Days" *** Do not import this pay item list into the IDOT electronic bidding system. 20 Where crossing the lane line markings is discouraged, the lane line markings shall consist of a normal or wide solid white line. The CMMS Supplement Documentation of Contract Quantities Guide document serves as a supplement to the departments Documentation of Contract Quantities Guide. 05 Local highway agencies may prescribe special colors for curb markings to supplement standard signs for parking regulation. On three-lane roadways where the direction of travel in the center lane transitions from one direction to the other, a no-passing buffer zone shall be provided in the center lane as shown in. A speed measurement marking is a transverse marking placed on the roadway to assist the enforcement of speed regulations. Standard: 03 Do Not Block Intersection markings shall be accompanied by one or more Do Not Block Intersection (DRIVEWAY) (CROSSING) (R10-7) signs (see Section 2B.53), one or more Do Not Stop On Tracks (R8-8) signs (see Section 8B.09), or one or more similar signs. In such applications, markers may be positioned in line with or immediately adjacent to a single line marking, or positioned between the two lines of a double center line or double lane line marking. Retroreflective and internally illuminated raised pavement markers are available in mono-directional and bidirectional configurations. These markings might be placed in advance of an unexpectedly severe horizontal or vertical curve or other roadway feature where drivers need to decelerate prior to reaching the feature and where the desired reduction in speeds has not been achieved by the installation of warning signs and/or other traffic control devices. 14 When diagonal or longitudinal lines are used to mark a crosswalk, the transverse crosswalk lines may be omitted. A wide dotted white lane line shall be used: Lane drop markings used in advance of lane drops at freeway and expressway exit ramps should begin at least 1/2 mile in advance of the theoretical gore. Navigate to Local Roads & Streets Special Provisions to view a complete listing of updates to the current Local Roads & Streets Manual. Parking space markings tend to prevent encroachment into fire hydrant zones, bus stops, loading zones, approaches to intersections, curb ramps, and clearance spaces for islands and other zones where parking is restricted. 1. bd01.dgn edge of shoulder greater or equal to 15' (4.5 m) driveway detail - distance between r.o.w.

To submit a request, send an e-mail to DOT.HwyStds@illinois.gov. 23 Where opposing offset channelized left-turn lanes exist, lane-use arrow markings should be placed near the downstream terminus of the offset left-turn lanes to reduce wrong-way movements (see Figure 2B-17). The longitudinal spacing of the chevrons or diagonal lines should be determined by engineering judgment considering factors such as speeds and desired visual impacts. 30 Where crossing the lane line markings is prohibited, the lane line markings shall consist of a solid double white line (see Figure 3B-12). Option: The bidirectional marker is capable of displaying the applicable color for each direction of travel. Letters and numerals should be 6 feet or more in height. The downstream end of the no-passing zone at point "b" in Figure 3B-4 is that point at which the sight distance again becomes greater than the minimum specified. Figure 3B-9 Examples of Dotted Line and Channelizing Line Applications for Entrance Ramp Markings. 0000568712 00000 n Standard: NOT FINDING WHAT YOU NEED? Support: Directional configurations also should be used to avoid confusion resulting from visibility of markers that do not apply to the road user. There is also a new compliance date in the Introduction, and a new publication added to Section 1A.11. Examples of channelizing line applications are shown in, Channelizing lines at exit ramps as shown in, Channelizing lines at entrance ramps as shown in, For all exit ramps and for entrance ramps with parallel acceleration lanes, channelizing lines shall be placed on both sides of the neutral area (see, For entrance ramps with tapered acceleration lanes, channelizing lines shall be placed along both sides of the neutral area to a point at least one-half of the distance to the theoretical gore (see Drawing C of, For entrance ramps with tapered acceleration lanes, the channelizing lines may extend to the theoretical gore as shown in Drawing B of. A normal line may be used to extend a wide line through an intersection. Revised MUTCD Maintaining Minimum Pavement Marking Retroreflectivity Support: Similarly, the passing sight distance on a horizontal curve is the distance measured along the center line (or right-hand lane line of a three-lane roadway) between two points 3.5 feet above the pavement on a line tangent to the embankment or other obstruction that cuts off the view on the inside of the curve (see Figure 3B-4).
