Bridges of up to 20' length constructed in the field.  All are made to withstand heavy loads, including horses, big game, and even trucks (where appropriate.)  Bridges are constructed of weather-resistant materials to handle moisture, snow loads, and heavy traffic in all seasons.  The 20' long by 5' wide bridge pictured has been engineered to withstand 10,000 pound loads.

Wet crossings can usually be handled with rolling dips and rock armoring, but in some cases a culvert or small bridge will be more effective, and even less costly over time.
