Bigge employs a number of modular ('jumper') bridges that may be used to span from barge to shore, for roll-on and roll-off operating, and across creeks and culverts. Most often modular bridges are used to "jump" permanent highway bridges of inadequate load carrying capacity. These modular bridges are used by jobs requiring specialized transport on platform trailers. Manufactured by Bigge, multiple bridges can be put together as required for especially long distances or wide loads.
