A mailbox installation that conforms to the following criteria will be considered acceptable unless in the judgment of the Highway Engineer, the installation interferes with the safety of the traveling public or the function, maintenance, or operation of the highway system.


Mailboxes shall be located on the right-hand side of the roadway in the direction of the delivery route except on one-way streets where they may be placed on the left-hand side. The bottom of the box shall be set at an elevation established by the U.S. Postal Service. The roadside face of the box shall be offset from the edge of the traveled way as follows: the width of the all-weather shoulder present plus 8 to 12 inches or on curbed streets, the roadside face of the mailbox shall be set back from the front face of a flat faced curb 6 to 12 inches or 6 to 12 inches from the back of a roll curb, or 8 to 12 inches behind the edge of pavement/road.

Where a mailbox is located at a driveway entrance. it shall be placed on the far side of the driveway in the direction of the delivery route.

Where a mailbox is located at an intersecting road, it shall be located a minimum of 100 feet beyond the center of the intersecting road in the direction of the delivery route. This distance shall be increased to 200 feet when the average daily traffic on the intersecting road exceeds 400 vehicles per day.


Mailboxes shall be of light sheet metal or plastic construction conforming to the requirements of the U.S. Postal Service. Newspaper delivery boxes shall be of light sheet metal or plastic construction of minimum dimensions suitable for holding a newspaper.
