Mailbox supports must be installed in accordance with departmental policies and for mailboxes.

Type 2 markers should be used to delineate mailbox supports. For further information, refer to the

Sign Crew Field Book

for installation requirements.

Cities should be encouraged to adopt the same or comparable standards for those installations on the state highway system within the incorporated city limits.

For safety and operational purposes, consideration should be given to placing installations a sufficient distance from the edge of the travelway to permit the delivery and receipt of mail without occupying the travel lane. Factors which should be considered include the number of mailboxes, average daily traffic, and sight distances. All weather access should be provided for these installations.

Newspaper delivery tubes may be attached beneath the mailbox on the downstream side, opposite of "Type 2" marker on the same support. Newspaper tubes should be of light sheet metal or plastic construction of minimum dimensions suitable for holding a newspaper. The name of the newspaper may be imprinted on the tube; however, no other printing or advertising should be allowed. Tubes should not be painted except to eliminate advertising.

For those installations requiring numerous mailboxes such as apartment complexes, mobile home parks, etc., the postal patron should be encouraged to place the installation on a low volume intersecting roadway or on private property whenever possible.

Neighborhood Delivery and Collection Box Units (NDCBU) should not be allowed inside the safety clear zone and preferably should not be allowed in the right of way

if safer alternates are present

. NDCBU installation is encouraged on a low volume intersecting roadway or on private property whenever possible. Where this is not practical, installation near the right of way line may be considered based on site conditions and safety considerations.

TxDOT crews shall maintain the walkway or path leading to the NDCBU if installed on state right of way, and the post office should maintain the NDCBU. TxDOT crews may install NDCBUs or other mailbox supports on county right of way with concurrence from the county and post office

.

Homeowners that do not own property adjacent to a state highway shall not install a mailbox on the state maintained highway. Maintenance Division recommends that the county, homeowners association, or the post office fund the mailbox support or NDCBU to be placed on the county right of way.

Any mailbox and/or support that violates the intent of this policy must be removed by the postal patron upon written department notification (certified letter). A standardized form letter (Form ) may be used for notification. If not removed within an acceptable period of time the department will remove the mailbox.
