MP&T Emphasis Points Guidance
- 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.
- Unneeded Signs
- Fully covered, removed, or otherwise completely eliminated from driver's view.
- Flagger signs covered/removed when flagger is not present.
- 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.
- 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.
- Sign Visibility
- Not hidden by foliage, roadway geometry or other signs.
- Approach sight distance is adequate.
- 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.
- 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.
- 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.
- 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.
- 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
- 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.
- 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").
- 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.
