Mapping Problem ?

Hey guys.. How are you doing :D
sooo.. I was mapping something for a friend.. and then I faced A really annoying problem..



See that sidewalk of the bridge thingy ? That I have arrows pointing to it ? It really pisses me off.. it blocks the way whenever I try to put a bridge leading to the place on the other side of water.. like you can't get on the bridge due to the sidewalk thingy.. I already tried with different bridges.. but none of them are working for me.. I solved this in another way like in the pic :



But as you see.. I looks ugly asf.. plus the fact that the beginning of the bridge of "Cement Blocks" is reaching to half the other bridge.. So I was wondering if any of you have a solution to this.. without making the bridge looking ugly or weird like a curvy on going up and down.. or a bridge of a random object like I did with cement blocks.. So... any one have any solution for this ?


P.S. : Sorry if that's not in the right section :D
