Typically the project goes like this:
1 - build the detour routes for the project as net new roads
2 - remove the current roads
3 - build the interchange
4 - remove the detours
It is common for these grade separations to have slight changes in road alignment. Even if they don't the over road doesn't build an approach on top of an existing roadway.
