Standard Plans
Standard Plans are separated into two categories; Miscellaneous (M-Standards) and Safety (S-Standards). The latest published version of the M&S Standard Plans is dated July 31, 2019. S-Standards contain details common for safety, such as delineators, lighting, signs, sign supports, traffic signals and accessories, pavement markings, and traffic control. Electronic files for the 2019 S-Standard Plans are available in English units only. Please visit the M-Standards page for details relating to guardrail, box culverts, roadway, super-elevation, and pavement.
