the fact that you have to connect the two bridges and then the beams will need more support in order to stay strong.

Modern arch bridges are held up by trusses. Typically these bridges span from two hundred feet up to eight hundred feet, or 4 meters. Arch bridges are smaller and span more narrow bodies of water.
the longest span of a truss bridge is 2.1 miles long
No. Bridges can span any gap in the terrain.
railroad bridges have a span between pilings, pediments, or bases.
The longest single span bridges are suspension bridges. Currently the longest is the Akashi-Kaikyo Bridge in Japan. Its main span is 1,991 metres.
They all seek to span a gap.
Max am Ende has written: 'Long span bridges' -- subject(s): Bridges
Major types of bridges, such as beam, arch, and suspension bridges, each have distinct strengths and weaknesses. Beam bridges are simple and cost-effective for short spans but can be limited in load capacity. Arch bridges are strong and aesthetically pleasing, effectively distributing loads, but they require solid abutments and are less suitable for very long spans. Suspension bridges can span great distances and support heavy loads, yet they are complex to design and build, making them more expensive.
The design, the load, and its resistance to weather. The biggest though, is the way it holds up weight. This really effects the maxium span. The biggest difference is the span of the bridges.
