Do I need to add a URI reroute for every single function for every single class?

Just wondering.
Because if so, it seems like this is going to be a real chore when building a huge website.

This is my current routes.

Code:

$route['tickets/index/(:any)'] = 'tickets/index/$1';
$route['tickets/(:any)'] = 'tickets/view/$1';
$route['tickets'] = 'tickets';
$route['create'] = 'create';
$route['login'] = 'login';
$route['(:any)'] = 'pages/view/$1';
$route['default_controller'] = 'pages/view';
