Sustainable Trail Bridge Design
Designing trail bridges based on trail-specific Trail Management Objectives (TMOs) is essential for providing the desired trail experience, for ensuring user safety, and for maximizing bridge longevity.
Understand and apply common construction specifications/trail management objectives such as corridor height/width, tread width, cross/outslope, protrusions, obstacles, and compaction.
Clear the corridor (brushing, logging out, hazard tree removal, rock/stump removal) in preparation for construction using proper pruning techniques.
Using hand tools, construct a trail with a full bench, raised tread, and/or combination that meets the construction specifications.
Safely use and maintain mechanized trail construction equipment (i.e. mini-excavators, skid steers, trail dozers, compactors, etc) to construct trail that meets construction specifications.
Utilize tools, often mechanical (i.e. excavators, harrow rakes, compact utility loaders, compactors), to meet specifications for final tread surface and backslope preparation and compaction, construction spoils management, and erosion control stabilization.
Construct drainage features that decrease erosion , including grade reversals, berms, ditches, and sheet drains.
Construct a water crossing structure (i.e. puncheon, turnpike, bridge) to span drainageways or wetland areas and raise the trail above the high water line while maintaining uninterrupted hydrology beneath the constructed feature.
Construct stone or wood retaining walls to bolster unconsolidated soils, gain elevation, or transition tread from rocks/natural barriers.
Install the appropriate treadway hardening technique for a trail given the slopes, soils, available material (wood, rock, gravel) and designed use, including advanced hardening techniques (i.e. turnpiking, rock culverts, boulder causeway, rock drains).
Build and maintain trail heads, parking lots, kiosks, sanitary facilities, camping facilities, traffic barriers, and directional signage.
Demonstrated ability to plan and implement the closure, reclamation, and revegetation of a trail segment.
