About this file
This document contains standard details for an Oregon Department of Transportation project to address culverts along OR58 using Automated Flagger Assistance Devices (AFADs). The project will require one or two AFADs, flaggers, temporary pavement markings, signs, tubular markers, and concrete barrier as shown on other standard detail sheets. When extended traffic queues develop during AFAD operations, the standard details direct protecting traffic by providing advance flaggers and signing according to the "Extended Traffic Queues Detail."
