The bridge is Route 12.(should be on your map)BUT if you wanna get to Fuchia,you have to go on Silent bridge(Route 12) and Walk through Routes 12-15!Lot `o trainers so watch out.
you can get this on the bridge that connects lavender town to fuscia city, in the house on the bridge
if you mean fire red, he is on the road to fushia city, both of them. he is asleep on the bridge that takes you from lavender town to fushia city and blocks the cycling road. use the pokeflute on him to battle him. he is on level 30 and is pretty hard to catch cuz he uses rest and is holding the chesto berry. he also knows snore so he can attack while he is asleep. i used the ultra ball on him when he is asleep and his hp is low.
You get it from one of the fisherman on Route 12/Vermillion City/Fushia City.

he is the fushia gym leader, u need to get passed the snorlax to get to fushia city which requires the pokeflute
