September featured the release of the 2020 Interim Revisions to the Standard Specifications for Structural Supports for Highway Signs, Luminaries, and Traffic Signals, 6th Edition as well as the LRFD Specifications for Structural Supports for Highway Signs, Luminaries, and Traffic Signals, 1st Edition. Both are available for free as PDF downloads from the AASHTO Store.
