This is more in line with the Federal MUTCD and accounts for more limited space in urban type jobs where the speed limit is 30 or less.  \nCENTERLINE MARKINGS  \nWhen paying for the double centerline yellow markings do not pay for them as two 4” solid line white but rather use the pay item…  \n2016 Spec…2582.502 4” DOUBLE SOLID LINE –material by LIN FT  \n2018 Spec…2582.503 4” DOUBLE SOLID LINE – material by LIN FT  \nINTERIM PAVEMENT MARKINGS – ITEM 2580  \nThere has been confusion regarding the use of this pay item and the quantities to be included. A group has been reviewing the use of interim markings and several problems have been identified. This pay item should only be used for same day pavement markings to be placed on bituminous lifts and milled surfaces. Striping for detours or full striping of the project for suspensions should be paid for under pavement marking (2582) pay items. (Normally paint) .  \nInterim markings do not include edge lines and the length of the skip will be 5 ft. with a 45 ft. gap. Quantities must include centerline marking for each lift including any milled surfaces. For two lane, two way roads, quantities for the no passing zones need to be included. These quantities are kept on record in the District Traffic Offices. When being paid for by the linear foot, the plan needs to indicate how many lifts were estimated, the amount of solid yellow line, yellow broken line (skip) and white broken line (skip) .  \nIf the interim markings are being paid for by the lump sum this information is not included in the plan but will be in the ProjectWise restricted file folder.  \nIn either situation, the plan must contain the detail for the interim pavement markings.  \nINTERIM STRIPING TYPICAL  \nThe interim striping typical can go in either the Traffic control section or the permanent pavement marking section. It should only be in one section and must be the typical as shown on the striping typical website. Make sure that the pay item is included in the Statement of Estimated Quantity.  \nMULTI COMPVS EPOXY  \nThe pay item for Epoxy has changed. MnDOT has maintained a Qualified Products List for Epoxy pavement markings; however, many of the products on this list are not ‘true epoxies’, one is a modified urethane and others are modified epoxies. In addition, there are other pavement marking materials for which a separate QPL was maintained (such as Polyurea) . OTST decided to combine these into a MultiComponent list.  \nThe new 2018 spec book has changed the 3590 specification to Multi-Component Liquid Pavement Markings and the pay item had to change as well.  \nThus, when using the 2018 spec book, do not use EPOXY as the pay item – use MULTI COMP instead.  \nONE DIRECTION LARGE ARROW  \nThe Type III barricade with a One-Direction Large Arrow at the end of the merging taper and another identical assembly at the beginning of the taper (if a Flashing Arrow Board was not used) has essentially been what Minnesota has been using for lane closures since Appendix B was published.  \nHowever, there was no language in TTC (Temporary Traffic Control) chapter of the MNMUTCD that allowed this use. The One-Direction Large Arrow is governed by language in Warning Signs Chapter 2C (2C.12) that limits its use to delineating a change in horizontal alignment for curves. Language was drafted for consideration by the Minnesota Committee on Uniform Traffic Control Devices, but it was found to not be in compliance with the Federal MUTCD.  \nPer a recent clarification from the FHWA, it cannot be used for merging tapers, though it will still be used for shifting tapers. Therefore, for all projects submitted for the January 26, 2018 letting or later must following the new layout as described below.  \nDue to this clarification, the Field Manual Committee has developed new layout, instead of the One Direction Lar","cbCaimY0os0c7zAN","https://ap.wps.com/l/cbCaimY0os0c7zAN","pdf",478680,10,"English","# CHAPTER 16: TRAFFIC\n## ADVANCE WARNING SIGN SPACING\n## CENTERLINE MARKINGS\n## INTERIM PAVEMENT MARKINGS - ITEM 2580\n## INTERIM STRIPING TYPICAL\n## MULTI COMPVS EPOXY\n## ONE DIRECTION LARGE ARROW\n## PREVIOUS METHOD NO LONGER ALLOWED - NEW METHOD","[{\"question\":\"How should advance warning sign spacing change for 0–30 mph work zones?\",\"answer\":\"The advance warning sign spacing for 0–30 mph is reduced from 300 feet to 100 feet to better align with Federal MUTCD guidance and limited urban job space.\"},{\"question\":\"What are the key constraints for using the interim pavement marking pay item (2580)?\",\"answer\":\"It should be used only for same-day pavement markings placed on bituminous lifts and milled surfaces.
