MDT standard plans

MDT publishes the standard plans and standard drawings required on Montana construction projects. The authoritative set always lives on the agency's official site — linked below — and every sheet opens in the PDFDepth workspace for markup, measurement, and review.

Find the sheet on the MDT site, copy the PDF link, and paste it here — the workspace opens it in your browser. Nothing is uploaded for storage; marking up and measuring happen on your device.

What MDT standard plans cover

  • Drainage details — inlets, pipe bedding, culverts, endwalls, and underdrain
  • Traffic control and signing — sign supports, pavement markings, temporary traffic control
  • Roadside safety — guardrail, barriers, attenuators, and terminal treatments
  • Pavement and earthwork — typical sections, joint details, slope treatments
  • Structures — retaining walls, noise walls, traffic signals, lighting, and ITS supports

Coverage varies by state — always verify against the current edition on the official MDT site. PDFDepth is not affiliated with MDT or the State of Montana.
