When necessary, provide commercially available mailbox supports constructed of a single 4-inch by 4-inch wooden post, a single 4-inch diameter wooden post or a single metal post.

Anchor plates are prohibited on metal posts. Provide commercially available post-to-mailbox assemblies. The Engineer will accept the mailbox supports and post -to-mailbox assemblies based on compliance with the specified requirements and visual inspection for condition at the point of usage.
847.3 Construction Requirements
Remove the existing mailboxes and supports, and lay the mailboxes and supports on the owner’s property. The Engineer will inform the mailbox owners that on ly mailboxes and mailbox supports that comply with the requirements of the U.S. Postal Service will be reinstalled. If the owner’s mailbox is unacceptable, it is the owner’s responsibility to provide an acceptable mailbox fo r reinstallation. If the owner’s mailbox support is unacceptable, the Contractor will provid e an acceptable mailbox support for re installation. The Contractor will reinstall the mailbox owner’s original mailbox if said mail box complies with U.S. Post Office requirements. If the mailbox owner provides a lightwe ight newspaper delivery box, the Contractor will install the newspaper box below the mailbox (on the side of the mailbox support) when the mailbox is reinstalled. If the mailbox owner chooses to reinstall their own mailbox, the Engineer will inform the owner of highway permit procedures, and advise the owner that the reinstallation must be approved by KDOT. When the mailboxes are reinstalled, use these guidelines for installation: Locate the mailboxes on the right-hand side of the roadway in the direction of the delivery route. 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, presence of sight distance constraints, right of way impacts, etc.
