  3. Lane Drops on Freeways and Expressways

  4. Lane Drops on Conventional Roads

  5. Auxiliary Lanes Between Ramps 2 miles or less

  6. Auxiliary Lanes Between Intersections Now to be widedotted lane line 1 mile or less

  7. Acceleration Lanes

  8. Deceleration Lanes

  9. Compliance Date Replace existing broken lane lines with dotted lane lines for non-continuing lanes: December 31, 2016 or resurfacing, whichever occurs first

  10. Section 3B.05 Other White Longitudinal Pavement Markings 2009 MUTCD 2003 MUTCD Standard for all exit and entrance ramps Channelizing lines shall be placed on both sides of the neutral area

  12. Section 3B.17Do Not Block Intersection Markings

  13. Section 3B.18Crosswalk Markings New marked crosswalks alone, without other measures designed to reduce traffic speeds, shorten crossing distances, enhance driver awareness of crossing, and/or provide active warning of pedestrian presence should not be installed across uncontrolled roadways with: • - ≥4 travel lanes • - Speed limit >40 mph, and • ADT > 12,000 without raised median or pedestrian refuge, or • ADT > 15,000 with raised median or pedestrian refuge
