  1. Channelizing devices placed near the off ramp will be spaced more closely together. Spacing requirements (D Max., 1/2D Max., 1/4D Max.) are shown in parenthesis next to the length dimension.
  2. The design criteria contained in Publication 13M (Design Manual Part 2 - Highway Design) should be used for determining the alignment.

  4. The temporary Exit (W25-4) sign shall be located in the temporary gore. It shall be mounted at a minimum height of 7' from the pavement surface to the bottom of the sign. This sign may be either black on orange or white on green. This sign may be the Exit Gore (W25-4) sign or a Type I through IV sign as shown on TC-8701D sheet 8 in Publication 111, Traffic Control-Pavement Markings and Signing Standards.

PATA 506 (Old PATA 37) Lane Closure Near A Freeway Or Expressway Entrance Ramp

  1. The acceleration lane should be maintained at the longest length that will accommodate adjacent tapers.
  2. If a ramp entering a freeway or expressway is normally controlled with a yield sign, then the yield condition should remain during temporary traffic control if both a and b are true:
    1. Available sight distance for traffic emerging from the ramp is greater than the minimum stopping sight distance shown in the MUTCD Table 6C-2.
    2. An acceleration distance of at least 200' is provided.
    3. If either a or b are not satisfied or if an engineering and traffic study has been approved with therecommendation for a stop condition, than implement a stop condition.
  3. When Stop (R1-1) signs are used to control ramp traffic, Stop Ahead (W3-1) signs shall be placed along the ramp. When Yield signs (R1-2) are used to control ramp traffic, Yield Ahead (W3-2) signs shall be placed along the ramp.
  4. Placement of the temporary Merge Right (W4-1R) sign is optional if the permanent Merge Right (W4-1R)sign is clearly visible and is within 500' of the location shown in this PATA.
  5. Refer to PATA 007 for installing advance warning signs for freeways and expressways.
  6. Refer to PATA 012 for arrow panel sizing

PATA 507 (Old PATA 38)
Two-Way Traffic On One Roadway Of A Normally Divided Highway

  1. The maximum length of temporary one-lane operation, excluding transitions, should not exceed approximately 3 miles. Temporary one-lane operations longer than approximately 3 miles shall only be permitted if justified by an engineering analysis of crossover locations, traffic operations, safety, and other related factors.
  2. The alignment of the crossover may be designed as a reverse curve. When the crossover follows a curved alignment, the design criteria contained in Publication 13M (Design Manual Part 2 - Highway Design) should be used.
  3. For existing concrete pavements, temporary bituminous overlays should be used as shown to cover misleading pavement joints.
  4. Refer to PATA 007 for installing advance warning signs for freeways and expressways.
  5. Refer to PATA 012 for arrow panel sizing.
