IDOTs Bureau of Design and Environment (BDE) issues the BDE Special Provisions four times a year. PDF NOTICE TO CONTRACTORS BULLETIN - idot.illinois.gov 01 If speed hump markings are used, they shall be a series of white markings placed on a speed hump to identify its location. When making modifications to these details, designers should review the MNMUTCD and Chapter 7 of the TEM. Option: Section 3B.16 contains information regarding placement of stop line markings near crosswalk markings. 09 Center line markings shall be placed on all paved urban arterials and collectors that have a traveled way of 20 feet or more in width and an ADT of 6,000 vehicles per day or greater. 04 Examples of channelizing line applications are shown in Figures 3B-8, 3B-9, and 3B-10, and in Drawing C of Figure 3B-15. Examples of parking space markings are shown in Figure 3B-21. 620.2 Pavement and Curb Markings (MUTCD Chapter 3B) Special Provision for Temporary Pavement Marking. 33 The ONLY word marking shall not be used in a lane that is shared by more than one movement. This link takes you to the 2009 MUTCD with Revisions 1, 2, and 3 incorporated. Share sensitive information only on official, secure websites. The typical details listed on this page represent the recommended pavement marking design; they may be added to the blank plan sheet border (see below) when assembling a Pavement Marking Plan for a particular project. Route numbers (route shield pavement marking symbols and/or words such as I-81, US 40, STATE 135, or ROUTE 10), Cardinal directions (NORTH, SOUTH, EAST, or WEST), Destination names or abbreviations thereof. These pavement markings can be helpful to road users in some locations by supplementing signs and providing additional emphasis for important regulatory, warning, or guidance messages, because the markings do not require diversion of the road user's attention from the roadway surface. 05 The minimum taper length should be 100 feet in urban areas and 200 feet in rural areas. Figure 3B-28 Example of the Application of Speed Reduction Markings. Because of the low approach angle at which pavement markings are viewed, transverse lines should be proportioned to provide visibility at least equal to that of longitudinal lines. Option: When crosshatch markings are used on paved shoulders, they shall be diagonal markings that slant away from traffic in the adjacent travel lane. Guidance: Option: On August 5, 2022, FHWA published a final rule in the federal register adding new provisions to the Manual on Uniform Traffic Control Devices (MUTCD) relating to maintaining minimum levels of pavement marking retroreflectivity. 22 An additional arrow or arrows may be used in a turn lane. 02 Word, symbol, and arrow markings, including those contained in the "Standard Highway Signs and Markings" book (see Section 1A.11), may be used as determined by engineering judgment to supplement signs and/or to provide additional emphasis for regulatory, warning, or guidance messages. 02 Channelizing lines may be used to form channelizing islands where traffic traveling in the same direction is permitted on both sides of the island. hb``b`` 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. A dotted white line marking shall be used as the lane line to separate a through lane that continues beyond the interchange or intersection from an adjacent lane for any of the following conditions: For exit ramps with a parallel deceleration lane, a normal width dotted white lane line shall be installed from the upstream end of the full-width deceleration lane to the theoretical gore or to the upstream end of a solid white lane line, if used, that extends upstream from the theoretical gore as shown in Drawings A and C of, For exit ramps with a parallel deceleration lane, a normal width dotted white line extension may be installed in the taper area upstream from the full-width deceleration lane as shown in Drawings A and C of, For an exit ramp with a tapered deceleration lane, a normal width dotted white line extension may be installed from the theoretical gore through the taper area such that it meets the edge line at the upstream end of the taper as shown in Drawing B of, For entrance ramps with a parallel acceleration lane, a normal width dotted white lane line shall be installed from the theoretical gore or from the downstream end of a solid white lane line, if used, that extends downstream from the theoretical gore, to a point at least one-half the distance from the theoretical gore to the downstream end of the acceleration taper, as shown in Drawing A of, For entrance ramps with a parallel acceleration lane, a normal width dotted white line extension may be installed from the downstream end of the dotted white lane line to the downstream end of the acceleration taper, as shown in Drawing A of, For entrance ramps with a tapered acceleration lane, a normal width dotted white line extension may be installed from the downstream end of the channelizing line adjacent to the through lane to the downstream end of the acceleration taper, as shown in Drawings B and C of. 04 Examples of lane line markings are shown in Figures 3B-2, 3B-3, and 3B-7 through 3B-13. Option: If used, advance speed hump markings should be installed in each approach lane. 07 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 Figures 3B-8 and 3B-10 and Drawing A of Figure 3B-9). 1. bd01.dgn edge of shoulder greater or equal to 15' (4.5 m) driveway detail - distance between r.o.w. Support: Each IDOT district may require additional documentation due to conditions specific to the District. Guidance: 04 Pavement marking letters, numerals, symbols, and arrows shall be installed in accordance with the design details in the Pavement Markings chapter of the "Standard Highway Signs and Markings" book (see Section 1A.11). 03 Lane line markings should be used on all roadways that are intended to operate with two or more adjacent traffic lanes in the same direction of travel, except as otherwise required for reversible lanes. )V01|rssS!ny%!Ayy)yyyp~piRIeA~0 vv )L 35 Lane-reduction arrow markings may be used in long acceleration lanes based on engineering judgment. Option: 0000001128 00000 n Retroreflective or internally illuminated raised pavement markers may be used as positioning guides with longitudinal line markings without necessarily conveying information to the road user about passing or lane-use restrictions. 01 Transverse markings, which include shoulder markings, word and symbol markings, arrows, stop lines, yield lines, crosswalk lines, speed measurement markings, speed reduction markings, speed hump markings, parking space markings, and others, shall be white unless otherwise provided in this Manual. Where it is desired to alert the road user to changes in the travel path, such as on sharp curves or on transitions that reduce the number of lanes or that shift traffic laterally, the spacing may be reduced to N or less. For questions, comments, or suggestions about specific Standard Drawings, please contact the Highway Design Section at (208) 334-8528. An engineering study should be performed before a marked crosswalk is installed at a location away from a traffic control signal or an approach controlled by a STOP or YIELD sign. The passing sight distance on a vertical curve is the distance at which an object 3.5 feet above the pavement surface can be seen from a point 3.5 feet above the pavement (see Figure 3B-4). 09 The individual triangles comprising the yield line should have a base of 12 to 24 inches wide and a height equal to 1.5 times the base. Will County Division of Transportation 16841 W. Laraway Road . 01 Do Not Block Intersection markings may be used to mark the edges of an intersection area that is in close proximity to a signalized intersection, railroad crossing, or other nearby traffic control that might cause vehicles to stop within the intersection and impede other traffic entering the intersection.
