Mining haul road bridges & grade separations
Corrugated soil–steel bridge solutions engineered for heavy mining trucks, deep embankments, and safe grade separation within active mine operations.
Heavy haul performance
Designed for off-highway mining trucks, dozers, and deep cover embankments.
Grade separation & safety
Separates heavy haul routes from site roads, conveyors, and pedestrian traffic.
Efficient installation
Bolted plate assembly enables streamlined construction with minimal disruption to mine traffic.
Engineered for heavy haul road performance
ViaPlate bridges function as soil–steel composite systems, where corrugated steel plates interact with engineered backfill to distribute loads efficiently. Each structure is sized through structural calculations based on specified live loads, cover depth, backfill conditions, and site constraints.
Heavy live loads
Off-highway trucks and earthmoving equipment.
Deep embankments & cover
Designed for variable cover heights and engineered backfill interaction.
Operational traffic flow
Grade separation reducing conflict points between heavy and light vehicles.
Structural corrugated steel plate tunnels
ViaPlate is a corrugated structural plate system forming soil–steel bridges and grade separations in arch, pipe-arch, or box-type profiles.
In mining environments, these structures are used to:
- Carry haul roads over site roads, conveyors, rail spurs, or watercourses.
- Create underpasses for light vehicles, service traffic, and personnel beneath busy haul routes.
- Construct access road bridges on mine approaches and internal networks.
The system integrates with concrete or MSE headwalls and wingwalls depending on site and impact requirements.
Applications in mining & access roads
ViaPlate soil–steel bridges are deployed across mining operations where reliable grade separation and heavy-load performance are required.
Carrying heavy haul routes above plant roads, conveyors, or service corridors.
Allowing light vehicles and staff to pass safely beneath active haul routes.
Stream and culvert crossings within mine infrastructure networks.
Configuration & structural options
Profile types
Arch, pipe-arch, and box-type profiles selected based on required clearance and site conditions.
Geometry & alignment
Variable spans and rises, including skewed alignments, to accommodate haul roads and site layouts.
Cover & backfill design
Structures sized according to specified live loads, cover heights, backfill parameters, and site constraints.
End treatments
Integration with concrete or MSE headwalls and wingwalls depending on structural and site requirements.
