a good tactic i did for building the bridge(it took me longer to make it this way,but hey it saved me materials and about doubled the length.)and that is that after every stack of blocks i placed, i'd go back to remove every other block, then continue with my new stack,and keep repeating.

by the way, if you build the bridge out of ebonstone, sprinkle purification powder all over the whole bridge. if you don't, then u got several eaters of souls to deal with too. i found that out the hard way.
