Introduction to Temporary Logging Bridges
The forestry industry faces unique challenges when accessing timber stands separated by streams, wetlands, and sensitive habitats. Traditional crossing methods often create significant environmental disruption, regulatory complications, and operational inefficiencies. E&H Manufacturing’s temporary logging bridges provide an innovative solution that balances operational needs with environmental responsibility.
Our stress-laminated timber bridges deliver reliable, durable crossing infrastructure specifically engineered for logging operations. Designed to support heavy equipment and fully loaded logging trucks while minimizing environmental impact, these portable structures can be quickly deployed, easily relocated, and efficiently removed when harvesting is complete.
Key Benefits for Logging Operations
Rapid Deployment in Remote Locations
Time is money in logging operations. Our temporary bridges are designed for efficient installation in remote forest locations with minimal equipment requirements. Most installations can be completed in a single day using standard forestry equipment like dozers or skidders.

Case Studies: Logging Applications
Multi-Phase Timber Harvest
A timber company needed multiple stream crossings during a 5,000-acre harvest operation. Traditional crossings would have required extensive permitting and created significant environmental disruption. E&H provided temporary bridges that were relocated throughout the project as harvesting progressed, maintaining operational efficiency while ensuring environmental compliance. The bridges supported fully loaded log trucks and heavy equipment while completely protecting stream habitats and water quality.
Results:
– Maintained harvest schedule despite multiple water crossings
– Reduced permitting timeline by 8 weeks
– Eliminated $125,000 in environmental mitigation costs
– Relocated bridges 5 times to support different harvest units
– Maintained full compliance with forestry BMPs
Sensitive Watershed Timber Management
A logging operation in a municipal watershed needed to access timber stands across multiple headwater streams. Water quality protection was paramount due to downstream drinking water supplies. E&H’s temporary logging bridges maintained access while protecting water quality throughout the harvest. Post-project monitoring confirmed that water quality parameters remained within baseline conditions throughout operations.
Results:
– Maintained all water quality parameters within baseline conditions
– Simplified regulatory approval process
– Reduced environmental compliance costs by 65%
– Completed harvest on schedule despite multiple water crossings
– Established positive relationship with watershed management authority
