Guidance:

 

  1.    The guide signs should indicate that the ramp is open, and where the temporary ramp is located. However, if the ramp is closed, guide signs should indicate that the ramp is closed.
  2.    When the exit ramp is closed, a black on orange EXIT CLOSED sign panel should be placed diagonallacross the interchange/intersection guide signs.
  3.    The design criteria contained in the AASHTO “Policy on the Geometric Design of Highways and Streets” (see Section 1A.11) should be used for determining the alignment.

 

Standard:
