Introduction
When access challenges threaten project timelines, operational efficiency, or emergency response, E&H Manufacturing’s temporary bridge solutions provide the reliable crossing infrastructure you need. Our professionally engineered stress-laminated timber bridges deliver exceptional performance for temporary applications across logging, construction, emergency response, and environmental projects—all while minimizing environmental impact and maximizing cost efficiency.
Designed to meet AASHTO HS-20-44 specifications and certified to carry loads up to 80,000 pounds, our temporary bridges combine the natural strength of timber with innovative engineering to create durable, portable crossing solutions that can be quickly deployed, easily relocated, and efficiently removed when no longer needed.
Key Benefits of E&H Temporary Bridges
Rapid Deployment and Removal
Time is critical in temporary access scenarios. Our stress-laminated timber bridges are designed for fast, straightforward installation with minimal equipment requirements. Most installations can be completed in a single day using standard construction equipment like a dozer, excavator, or boom truck. When the crossing is no longer needed, our bridges can be quickly removed without leaving permanent infrastructure or environmental damage.
Environmental Protection
Traditional stream crossings often create significant environmental disruption and regulatory complications. Our temporary bridges span waterways without in-stream construction, eliminating streambed disturbance and water quality impacts. This approach preserves aquatic habitats while simplifying regulatory compliance and reducing environmental mitigation requirements—benefits that translate directly to cost savings and accelerated project timelines.
Cost-Effective Access Solutions
Our temporary bridges deliver exceptional return on investment through:
– Reduced project timelines through improved site access
– Elimination of expensive in-stream construction and associated mitigation
– Simplified permitting and regulatory compliance
– Reusability across multiple project phases or locations
– Reduced site restoration costs upon project completion
These economic advantages make our temporary bridges the most cost-effective solution for challenging access requirements.
Versatility Across Applications
E&H temporary bridges adapt to diverse operational needs:
– Logging and Forestry: Access across streams for equipment and timber extraction

Success Stories
Logging Operation Stream Crossings
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.
Emergency Flood Response
When spring flooding washed out multiple rural bridges in a Midwestern county, E&H’s temporary bridges restored critical access within days. The bridges provided stable crossings for emergency vehicles, utility restoration crews, and resident access while permanent replacements were designed and constructed. The rapid deployment minimized community disruption while providing reliable infrastructure throughout the recovery process.
Environmentally Sensitive Construction
A commercial development project required access across a protected wetland area during construction. Environmental authorities required a solution that would provide necessary access while protecting the sensitive ecosystem. E&H’s temporary bridge solution provided the necessary access while satisfying regulatory requirements and site evaluations before beginning construction. E&H’s temporary bridge solution provided the necessary access while satisfying regulatory requirements and protecting the stream ecosystem. The bridge was later repositioned to support construction activities before permanent infrastructure was completed.
