Solving Temporary Crossing Needs

Portable bridges are essential when permanent installations aren’t feasible and avoiding a crossing isn’t possible. TerraCross bridges provide an engineered solution to quickly and easily bypass small rivers and ditches to maintain seamless access for equipment, materials, and personnel throughout the duration of your project. Additionally, they can protect underground equipment, such as buried gas pipelines by providing an air-bridged pathway over the impacted area. 

Unlike commonly used timber mat bridges that are made from mixed woods of different grades and quality, the engineered TerraCross bridge is made from welded metal. It has certified weight specifications and provides consistent performance. It isn’t susceptible to deterioration like wood so sudden bridge failure due to accidental overloading or internal unseen wood rot is no longer a concern. And the durable qualities of the TerraCross means it can be relocated and reused across different projects, providing a flexible solution for various construction needs. 

Keep your project on time, on budget, and safer with a TerraCross bridge solution.

Prior to deploying the portable bridge to your site, our quality assurance team uses a 26-point inspection to ensure it is field ready.

In addition to providing a safer solution to creek, ditch, or ravine crossings, the TerraCross Portable Bridge can be utilized as an airbridge when crossing underground pipelines with heavy equipment.

Yes. OSHA-compliant handrails are pinned to the temporary bridge.

Due to the critical importance of proper installation, it is recommended that the TerraCross system be installed by a Sterling field operations team. If you want your crew to install the TerraCross portable bridge, a Sterling site advisor must be on site to supervise the installation and breakdown.

All sites must be reviewed and/or inspected by trained Sterling personnel prior to rental agreement.

The TerraCross Temporary Bridging system is easily installed with standard equipment used to create temporary access roads like excavators and front-end loaders.

Depending on the soil conditions and grade change, additional bearing components, soil testing, and/or site preparation may be required. These conditions will be identified during the site review and inspection.

The strength and integrity of the TerraCross design are based on the engineering properties of the TerraLam mat, therefore, it is an integral component of the TerraCross Temporary Bridge system relative to both the bearing surface and the main travel deck. Installing TerraLam with other mats will compromise the safety of the unit.

Installation time depends on several factors, such as site access, soil conditions, and geography. Under ideal installation conditions, the complete system can be installed in as little as two hours to less than one full day.

All components of the TerraCross 40 can be shipped on a single standard flat bed. The TerraCross 56 will ship on two standard flatbeds.
