Building Permits for the delivery and installation of an industrial, temporary vehicular bridge can be the simplest thing or a giant headache. First thing to be aware of: do NOT just ask your neighbor what they did to install their equipment bridge 10 years ago. Building and civil engineering regulations change, and what was allowed then with a simple one-page permit may now be woefully inadequate for modern heavy construction standards.

Do not be tempted to just skip the whole process and think, “No one will notice if I’m installing a temporary construction bridge up in the back woods somewhere for a 1-month project.” I know this from personal experience. We had a project—it was a simple property upgrade—and the local inspector stopped by, looked me in the eye, and said, “You knew better than this.” We had to halt the industrial project site, engage an architect, and prepare formal structural drawings. We got the permit easily enough, but it caused a major logistical delay.

Core Industrial & Structural Permits to Consider:

  • Local Building Permit: Almost every jurisdiction requires a standard building permit for a temporary or portable vehicular bridge designed for heavy equipment transport. All of Spanweld Bridges’ engineering drawings are stamped by a licensed structural engineer, which goes a long way toward getting quick approval. Be sure to discuss HOW the bridge is being used with local planning officials. A short-term temporary rental bridge for heavy civil construction may involve a completely different application process from a vehicle bridge permanently installed over a small ravine on a residential driveway, even though the structural design of the bridges is virtually identical.

  • Floodplain Development Permit / No-Rise Certification: If your equipment stream crossing crosses a FEMA-designated floodplain, you will need certification to show that the temporary bridge structure will not cause a “rise” in floodwaters or block flowing water.

  • Zoning or Land Use Permit: This ensures your temporary access bridge complies with setbacks, property lines, and local land-use regulations. For instance, it verifies that the bridge footings aren’t sitting on your neighbor’s property and aren’t interfering with any utility easements.

  • Right-of-Way (ROW) / Driveway Encroachment Permit: Required if the temporary industrial bridge connects private property directly to a public road, or if heavy civil construction equipment needs to operate within the public easement during installation.

  • State and Federal Land Permits: If the portable bridge is to be installed on state or Federal lands, is going over a navigable waterway, or is being deployed in a habitat of endangered species, additional environmental permits will be required.

IF YOUR BRIDGE IS TRULY A CLEAR-SPAN TEMPORARY BRIDGE FOR LIMITED-TIME SITE ACCESS, THE PROCESS MAY CHANGE SLIGHTLY.

There is often a “fast-track” permit pathway for short-term industrial projects:

  • Full stamped drawings by a licensed structural engineer with specific heavy-duty load ratings and details showing exactly how the bridge will be used will always be required. Clearly showing that this is a temporary bridge rental project for heavy-duty construction traffic and not for permanent public vehicle traffic can help satisfy local safety concerns.

  • Federal (USACE) – Nationwide Permit 33 (NWP 33): The U.S. Army Corps of Engineers has a specific fast-track category called NWP 33 (Temporary Construction, Access, and Dewatering). This requires you to submit a site restoration plan showing you will return the waterway and terrain to original conditions once the temporary bridge is uninstalled.

  • State DNR / EPA: Most states offer an expedited General Permit or a “Temporary Waterway Crossing” authorization for industrial site access. You will be required to show environmental “best practices,” such as installing geotextile fabric under gravel approaches to minimize site impact and avoid disrupting waterways.

  • FEMA Floodplain & “No-Rise”: Often the biggest hurdle here. If the temporary bridge is over an active floodway, plans may be required showing how the structure will not cause a rise, or if that is unavoidable, a rapid-response plan must be submitted showing how the portable bridge can be removed at short notice in the event of a flood. A full hydrological study may be waived under certain conditions if you are only using a temporary or portable construction bridge for a short period of time.
