Please help, I have reached level 10 and completed all possible side quests

And the Main Quest is "On to Lakeview", but when I go to the bridge, it was broken and here I thought I need to go to sleep for it to be rebuilt, but it wasn't, and I repeated this 2-3 times but nothing happens

It's not the bridge. On the world map, go to the south east to the check point at the watch tower. They will let you through after you have permission from the mayor, which you should already have after beating the orc in the cave.
