We may suggest 20ft (6m) to be the criteria but i insist this is practically too short. Bridge span of 20meters or less may be a good standpoint reference of "short span".
the beam has a total volume of 60ft 3 what is the maximium horizontal gap that the beam can span
A bridge is a structure built to span a physical obstacle, such as a river or road, allowing for transportation over it. An elevated highway, on the other hand, is a roadway raised above ground level, often supported by columns or beams, allowing vehicles to travel over existing roads or terrain. While both structures elevate traffic, bridges primarily connect two points, whereas elevated highways are part of a continuous roadway system.

What size steel I beam do I need to span a 32 feet garage with a floored storage above and no posts
A bridge's span is the length that crosses the gap.

The span is the distance between supports. The sum of the span lengths is the bridge length.
it is the length of the bridge in the harry potter movie
A span on a bridge is the distance between supports such as from pier to pier. A bridge can have several supports over its length. A bridge length includes the entire bridge.
Sydney Harbour Bridge, completed in 1932, has an arch span of 503 metres, or 1650 feet. Its total length is 1149 metres, including the approach spans. At the time of its completion, it fell 1.2 metres, or 4 feet, short of the Bayonne Bridge in NJ as the longest steel arch in the world, but it it much more eye pleasing. It is still the world's highest arch bridge. The "coat hanger" as it has been called by locals, as of 2009, has dropped to 5th in measured central span length, the two longest being in China.
the total length of Millau viaduct bridge is 2460 mtrs or 1.53 mill. this is the world tallest' bridge that linking Paris to mediterranean.
Probably not. Length would be the entire length to the point the road starts. The span would be the section with air under it. Depending on the design, there could be a fair amout of the bridge supported by dirt or concrete at either end.
It is 4,200 feet.

for short distance half circle bridge is better and for large span flat bridge is used.
