MP&T Emphasis Points Guidance

1. Sign Condition and MUTCD Consistency
   • Refer to Quality Standards for Work Zone Traffic Control Devices for acceptable condition levels.
   • Faded and deteriorated panels not acceptable.
   • Reflectorization in good condition and clean.
   • Non-standard legends not acceptable
   • Non-standard colors not acceptable
   • Signs look as they appear in MUTCD §6F, see attached pages 6F-1 to 6F-2 and 6F14 to 6F20.
2. Unneeded Signs
   • Fully covered, removed, or otherwise completely eliminated from driver's view.
   • Flagger signs covered/removed when flagger is not present.
3. Low-Mounted Signs
   • No low mounted signs permitted, except for flexible panels meeting current specifications.
   • Adhere to MUTCD §6F, for details see attached pages 6F4 and 6F6.
4. Advance Warning
   • No overlapping, conflicting or unneeded advance warning signs.
   • Refer to MUTCD Appendix 6H for layout reference details, see attached various pages 6H4 to 6H79 for typical approach diagram layouts.
5. Sign Visibility
   • Not hidden by foliage, roadway geometry or other signs.
   • Approach sight distance is adequate.
6. Flagger Signs
   • Used only when flagger is present and visible to the motorist. They must be covered or removed at all other times.
   • Adhere to attached MUTCD page 6E-2.
7. Flagger Control
   • Stop/Slow paddles are to be used where appropriate.
   • Flaggers must be positioned to provide adequate visibility and to enhance the safety of the flaggers.
   • Adhere to MUTCD §6E, see attached pages 6E3 and 6E4.
   • Refer to __DOT EI 93-022, Flagger Station Enhanced Setups for further guidance.
8. Pedestrian and Worker Safety
   • Reasonably smooth, continuous, safe and convenient travel way provided and maintained for anticipated bicycle and pedestrian traffic at all times.
   • Adhere to MUTCD §6D, see attached pages 6D-1 to 6D-5.
   • Refer to State spec for further guidance.
9. Merge Taper Lengths
   • Location of tapers should provide optimal visibility to approaching motorists.
   • Meet minimum requirements in MUTCD §6C-08, see attached pages 6C-9 to 6C-11.
   • Refer to State Spec for further guidance.
10. Temporary Concrete Barrier
    • End flared minimum of 12 feet away from pavement on high-speed roads, if not flared, must be protected by impact attenuator device.
    • Barrier-flares preceded by channelizing devices and buffer spaces.
    • Barrier runs designed to fully protect the hazard.
    • Adhere to State spec
11. Pavement Bumps
    • Reasonably smooth riding surface maintained.
    • Transverse pavement joints and paving rebates must be treated with temporary shims (60:1 taper).
    • "Bump Ahead" signs posted upstream on approach.
    • Channelizing device or object marker placed at bump.
12. Temporary Sign Supports
    • All temporary supports not protected by guiderail must meet requirements of State Standard Specifications.
    • Type A metal supports must meet State Standard Material Specifications
    • Stub heights must not exceed 100 mm (4").
13. Channelizing Devices
    • Good physical condition.
    • Placed at outer limits of the roadway available for use by vehicles.
    • Adhere to MUTCD Chapter 6F see attached pages 6F41 to 6F43.
    • Refer to State Spec for further guidance.
