Segment Landscape Spline Question

I’m new to Unreal, and I’m starting out with basic level design. I am to the point of using the Landscape splines to lay road along the terrain, but what do you do when you get to where you want to place an intersection? Is this something where you’d want to use a static intersection prop and then try to align to that? Or are there ways to dynamically set the intersection as roads intersect with one another? I have the same question when it comes to laying out railway track using the same method.
