Help? bad builder alert

[Poopoooter]

I have nearly finished my wall around my town but i've come to a small river leading into the town and i'm pretty terrible at doing sea entrances (i've tried) - i was looking for the entrance to connect to the walls on both sides and be like a arch or something? The cords of my base are -2500 65 -1200.

You will see the river and know where i mean, if anyone would like to build this arch i would very much like it
