0 Crosswalk markings provide guidance for pedestrians who are crossing roadways by defining and delineating paths on approaches to and within signalized intersections, and on approaches to other intersections where traffic stops.

Option: Support: 26 On approaches to intersections, solid white lane line markings may be used to separate adjacent through lanes or adjacent mandatory turn lanes from each other. Guidance: 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. 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). In the case of a lane drop at an exit ramp or intersection, such a solid white line may replace a portion, but not all of the length of the wide dotted white lane line. 09 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 Figure 3B-8. The Standard Drawings are for use on Idaho Transportation Department (ITD) and Federal-Aid projects. 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. When supplementing solid line markings, raised pavement markers at a spacing no greater than N (see. When raised pavement markers substitute for solid line markings, the markers shall be equally spaced at no greater than N/4, with retroreflective or internally illuminated units at a spacing no greater than N/2.

Other markings, such as yellow delineators, yellow channelizing devices, yellow raised pavement markers, and white crosswalk pavement markings, may also be placed in the flush median area. 05 If transverse lines are used to mark a crosswalk, the gap between the lines should not be less than 6 feet. 15 When drivers yield or stop too close to crosswalks that cross uncontrolled multi-lane approaches, they place pedestrians at risk by blocking other drivers' views of pedestrians and by blocking pedestrians' views of vehicles approaching in the other lanes. If diagonal or longitudinal lines are used without transverse lines to mark a crosswalk, the crosswalk should be not less than 6 feet wide. A single solid yellow line shall not be used as a center line marking on a two-way roadway. 10 White chevron crosshatch markings (see Section 3B.24) may be placed in the neutral area of exit ramp and entrance ramp gores for special emphasis as shown in Figures 3B-8 and 3B-10 and Drawing A of Figure 3B-9. 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. Can IDOT provide any cores that were previously taken for the existing conditions on I-55. Directional configurations also should be used to avoid confusion resulting from visibility of markers that do not apply to the road user. <]/Prev 655708>> The pliant polymer pavement markings shall consist of a mixture of high-quality polymeric materials, pigments and glass beads distributed throughout its base cross-sectional area, with a layer of wet retroreflective media bonded to a durable polyurethane topcoat surface. The centerline marking for a two-lane roadway where passing is allowed in either direction shall be a 4-inch broken yellow line composed of 10-foot segments separated by 30-foot gaps. Standard: An arrow at the downstream end of a turn lane can help to prevent wrong way movements. 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. 04 Except as provided in Section 8B.28, stop lines shall not be used at locations where drivers are required to yield in compliance with a YIELD (R1-2) sign or a Yield Here To Pedestrians (R1-5 or R1-5a) sign or at locations on uncontrolled approaches where drivers are required by State law to yield to pedestrians. or Alteration (FAA Form): FAA 7460-1, Revenue-Generating Facility Eligibility Evaluation Form (FAA), Detailed Project Justi&cation/Description, Airport Snow Removal Equipment Inventory Sheet, Apron Size Calculations for Transient Aircraft, Guide for Justifying Snow Removal Equipment Buildings (December 2011).
