Interim Addenda to the Alaska Traffic Manual

Effective August 14, 2015

Interim Addenda represent approved revisions to the Alaska Traffic Manual (ATM). The ATM is the standard for traffic control devices on public roads in Alaska. It consists of the Manual on Uniform Traffic Control Devices (MUTCD) and the Alaska Traffic Manual Supplement (ATMS). It references the Alaska Sign Design Specifications (ASDS), which is the sign layout standard for Alaska public roads.


Alterations to the current ATM will be incorporated into the next edition.
