That depends on what it carries. All joist/beam manufacturers have span tables that will help you determine this.
Use a steel beam.. That would be code.. steel w10x15 (50ksi) I beam.
It actually depends on the type of beam it is. If it is a cantilever, the formula would be PL/2 and for a simply supported beam it would be PL/4
Depends on the loads and the properties of the beam. Consult a structural engineer.
1'*1'
the beam has a total volume of 60ft 3 what is the maximium horizontal gap that the beam can span
250 Feet
1.50 meter from the support is the max. safe length cantilever beam
250 Feet
250 feet

That question cannot be answered without knowing the load on the beam.

two beam bridges linked together

Span/load beam questions really cannot be answered. You will need to have the plans looked at by a engineer. At the very least the lumber yard selling the beam may have an on-staff engineer to have a look at it.
Arch bridge: the span beam of bridge is the shape of an arch & the load is diverted in compressive method. Beam bridge: the shape of beam span is of simply supported or continuous. here the load is diverted through bending compression method.
