Announcement from WV Executive Magazine

E&H Manufacturing, Inc. is announcing the expansion of their stress-laminated timber bridge line. They recently introduced the new line at the EXPO, coordinated by the Contractors Association of WV.

“We have expanded our timber bridge line from 2 to 7 models,” stated David Haney, President of E&H Manufacturing. “We have noticed increased interest in these products and just felt it was the right time to expand our line,” he added.

The bridges are pre-engineered and pre-fabricated, stress-laminated timber bridges certified to carry a maximum load of up to 80,000 pounds. Several models meet American Association of State Highway Transportation Officials (AASHTO HS-20-44) Specifications.

The E&H bridges are made from CCA-treated lumber encased in a steel channel. The patented Shear Key design allows bridges to operate as a single, solid structure with weight distributed evenly across the entire bridge. Each bridge is designed for fast, easy installation with a dozer, excavator or boom truck.

This timber bridge system meets and exceeds Best Management Practices for stream crossings by minimizing stream siltation and erosion during installation, use, and removal.

Stress-laminated timber bridges are prudent in situations where a temporary or portable bridge is needed and make attractive permanent bridges where applicable.

These bridges are constructed by standing 2 x 6, 2 x 8, 2 x 10, or 2 x 12 boards on edge and hydraulically compressing them together and locking the stress in place with stressing rods, to create a strong, durable structure that can withstand heavy loads and constant use.

Here are some reasons why stress-laminated bridges are important:


Stress-laminated timber bridges are pre-engineered with certified load capacities for safety and certainty that they are adequate for your use.

Quick and easy installation:

Stress-laminated timber bridges can be shipped easily and installed quickly, which makes them ideal for emergency situations or for use where a permanent bridge is not feasible.


Stress-laminated timber bridges are typically less expensive than other types of bridges, which makes them a cost-effective option for many applications.


Stress-laminated timber bridges are designed to be very durable and to withstand heavy loads and constant use. This makes them ideal for use in areas with high traffic volume, such as construction sites or military bases.

Easy maintenance:

Stress-laminated timber bridges require minimal maintenance, which makes them a low-maintenance option for many applications. This can save time and money in the long run.


Stress-laminated timber bridges can be used in a variety of settings and applications, from construction sites to military operations to temporary events like concerts or festivals. Even state parks and recreational sites.

Overall, stress-laminated timber bridges are an important type of bridge that offers many benefits, including certified load capacities, quick installation, cost-effectiveness, durability, low maintenance, and versatility. These factors make them an ideal choice for many different applications and settings.
