If you have any slope I would probably not build a bridge but run a 
drain line. Just like you would in a field. I did that at my old place. 
The back yard became a pool every year. Took a roll of 4" perf pipe and 
4 12' sections of 10" plastic. Dug a long trench across the yard with 
very little slope. Off of that I dug feeder trenches at an angle. Laid 
in the pipes, backfilled with creek run gravel and buried the entire 
thing. Used the extra dirt to level the yard. Worked great. Basically 
just like a septic leach field in reverse. To keep animals out I used 
some stainless 1/4" rods and just drilled holes so there was a grid on 
the end.
