Hi. I just want to seek advice about bending a bridge? I would like to be turning slightly to the left like a train rail. something like that. Here is a sample… Thank you. 
Wrong section to ask. But anyway, try the Curve modifier, it bends meshes along curves.
I find it’s easier to understand the curve modifier’s behavior if you think of it as placing the object at the start of the curve and then making the object follow the curve from there.
Thanks. sorry for the wrong post. anyway. I’m pretty having problem with the curve because I am using it with array,
Curve should be at the end of the modifier stack.

Here’s couple of examples.
