Pyrenees stages - spectator advice appreciated!

As a 30th birthday present my family booked me a trip to Pyrenees to watch some tour stages (bucket list item!). We're staying in Loudenvielle so we won't need to travel for the Peyragudes stage, however there's a couple of stages where we'll have a couple of hours drive.

Looking at Col d'Aubisque and maybe Port de Lers on the other days. My question is what time roughly/in anyone's experience do these roads close? If we were to get there early morning (say 7am) and hike would we be able to get close? We're more than prepared for a couple of hours hike. Detailed road closures aren't out yet so looking more for approximations based on other years in similar areas.

Any advice appreciated!
