Section 532.320 Location
Considerations
a) When practical, mailbox turnouts should be located on the near
side, in relation to direction of traffic, from a private entrance or side road
to incorporate the entrance or roadway surface into the turnout length.
b) A location that would require or encourage a backing movement
by the postal patron or mail carrier should not be considered.
c) Wherever practical, mailboxes should be grouped to minimize
the number of stops required to serve the boxes.
d) When adjacent mailboxes are close together, and adequate
shoulder width exists, consideration should be given to a continuous surfacing
to eliminate as many off-on-movements as possible.
e) Where existing roadway shoulders are of adequate width, and
adequately stabilized, no additional turnout surfacing will be provided.
f) The mounting of mailboxes back of barrier curbs which would
cause stopping in a traveled lane should be discouraged. Postal authorities
and affected postal patrons should develop alternate means of mail delivery.
