Design, Construct, and Maintain
The USDA Forest Service Standard Trail Plans and Specifications are for the design, construction, and maintenance of National Forest System trails and trail bridges. These plans and specifications also are available for other Federal, State, and local agencies, communities, trail partners, volunteers, and entities.
The Standard Trail Plans and Specifications reflect current Forest Service trail management efforts and the agency’s Trails Data Dictionary for constructed features and tasks. The Forest Service’s National Technology and Development Program (T&D) developed them in conjunction with the agency’s National Trails Program, with funding and support from the Federal Highway Administration, Recreational Trails Program. These Standard Trail Plans and Specifications supersede the 1996 USDA Forest Service, Standard Drawings and Specifications for Construction and Maintenance of Trails.
How to Use Plans and Specifications
The Standard Trail Plans and Specifications were developed to assist with trail design, construction, maintenance, inventory, condition assessment, and the assembly of trail construction plan packages. The Standard Trail Plans and Specifications include specifications, pay items, and plans
Specifications and Pay Items
- Specifications (PDF and Word)
Specifications are written requirements for performing work.
- Pay Items (PDF and Word)
Pay Items are specific items of work for which a unit and price are provided in a contract.
The Standard Trail Plans are comprised of Standard Trail Drawings that show the location, type, dimensions, and details of trail work.
- The Standard Trail Plans are provided in United States customary units and are available below as PDFs (portable document files) and AutoCAD files. In AutoCAD, when using a postscript printer, this STD.ctb file should be used so line weights print as displayed (STD.zip).
- The Standard Trail Drawings are to be used as-is, with trail and site-specific dimensional needs additionally recorded on each sheet. If the Standard Trail Drawings are modified, the title block must be changed to “Special Project Specifications ” to reflect the change.
The Forest Service Standard Trail Plans are available as compiled sets of PDFs or as individual drawings.
This section contains standard drawings that are normally included in every trail or trail bridge plan package, such as the title sheet, vicinity map, work list, etc.

This section includes standard trail bridge plans for timber and prefabricated steel bridges.
Standard trail bridge plans for timber and prefabricated steel bridges have been approved by Forest Service Washington Office Director of Engineering and Washington Office Director of Recreation for use on National Forest System lands. The standard trail bridge plans are for typical superstructure designs and abutment details commonly used. The plans are not meant to be used as individual drawings. The designer should download all associated plans for the bridge type to ensure they have a complete trail bridge package.
A qualified engineer with trail bridge design experience must approve the use of these Standard Trail Bridge plans for each trail bridge project. Proper bridge siting and design includes many other aspects such as siting, hydrology, hydraulics, foundation, etc. Forest Service Trail Bridge design requirements are found in Forest Service Directives Forest Service Manual (FSM) 7723 and Forest Service Handbook (FSH) 7709.56b, Chapter 80 and in Technology and Development Center’s publication “Locating Your Trail Bridge for Longevity”.
On Forest Service projects, these plans may not be modified without Regional Engineer approval (except for populating the Structure Table on page 1 for each bridge type).
Non-Forest Service entities are welcome to use these trail bridge plans, but must take full responsibility for their use. We further recommend they seek review and approval from their qualified engineer of record for the project.
Trail Bridge Plans are provided below in a combination of editable AutoCAD .dwg and non-editable .dwf formats. Regional Bridge Engineers retain editable .dwg versions of the AutoCAD .dwf plans provided here.
