Mailboxes may be located on the left-hand side of the roadway on one-way streets. Embed the mailbox support post into the ground a maximum of 24 inches. Do not embed the post in concrete unless the mailbox support design is shown to be NCHRP 350 compliant when so installed. Set the mailbox according to the Mailbox Guidelines established by the U.S. Postal Service. If there is a question as to the proper location of the mailbox, contact the U.S. Postal Service (local Post Office) for guidance.
For roads not on the state highway system, e.g, roads under city, county or township jurisdiction, the mailbox offset may be less than the distances outlined ab ove and will be determined on a case-by-case basis in consultation with the owner of the facility. Items to be considered include, but are not limited to, roadway width, shoulder width, traffic volumes, pr esence of sight distance constraints, right of way impacts, etc.
