Technically the only difference is the spanlength. Culverts are upto 6 m length whereas Bridges are longer than 6 m.
Again, Bridges are classified as Minor Bridges if the span ranges from over 6 m up to 60 m and as Major Bridges if the are longer than 60 m.
Span is defined as the c/c distance between two successive expansion joints if it's a multispan Bridge over piers and between the inner surface of the dirt wall to center of the expansion joint over the adjacent pier if it's an abutment span
A culvert is a structure that can allows water to flow under a road, railroad, trail, or similar obstruction from one side to the other side. Typically embedded so as to be surrounded by soil, a culvert may be made from a pipe, reinforced concrete or other material.
