I've moved troops over the bridge on the east and that on the west, but it still says I did not secure the two main bridges.

1. There's a bridge in the middle. Is that it?
2. Isn't there some easy way to highlight where the objectives are?

Any help appreciated.

I think secondary objectives are highlighted by default with a flag pole with a silver base. Those bridges for example.

Click on the objective itself would bring you to the objective, so if you click on the x of the secondary objective or any objective stated will automatically brings you to highlight that objective.

The 2 bridge you are looking for is the 2 bridge that have a flag with silver bottom guarded by an engineer each, on the left you will face AT cover fire while the right bridge have a Stuart and bunker supporting it.

General fact is that gold base flag pole is primary objective, silver is secondary while bronze is minor objective

Thanks to you both!
