Vollavia 4-Way (Std Roads)

I've been playing with this interchange design recently. It's essentially an inverted Divided Volleyball interchange, but made in the style of a Pinavia. Like the Divided Volleyball interchange, this uses just 4 bridges which means it would be very economical to build and maintain if it were to be built in real world. The main down-side is that a realistic version would have to be quite big as it would need quite a bit of space for realistic curves and gradiants. It's also basically an inverted and slightly enlarged version of this intersection:

I've added multiple versions to the Steam Workshop, including larger versions that use roads from the Mass Transit DLC, but this version just uses the standard roads.
