with the AASHTO (American Association of State Highway and 
Transportation Officials) Transportation Glossary, a bridge is defined 
as a structure including supports erected over a depression or an 
obstruction, such as water, highway, or railway, and having a track or 
passageway for carrying traffic or other moving loads, and having an 
opening measured along the center of the roadway of more than 20 feet 
between undercopings of abutments or spring lines of arches, or extreme 
ends of openings for multiple boxes; it may also include multiple pipes, 
where the clear distance between openings is less than half of the 
smaller contiguous opening.
