Is there a certain setting I can use to get rid of the ugly curtain under bridges or do I need a top level graphics card?

It´s not possible as far as I know. They are part of the 3D models themselves as a result of photogrametry. It´s something to improve definitely. Also the road traffic doesn´t go via the bridge but at water level in most cases.
Bridges need to be done manually to remove that. If you check sites like Flightsim.to, you can find lots of hand-done replacements.
Or you could just turn off PG and you’ll see normal bridges…Depending on where you fly this may or maybe not a big deal.
