routes help - adds question mark.

I misunderstood your question the first time, that's why I brought up the URI-routing feature.

Modifying application/config/routes.php is cool if you want to modify CI's default behaviour towards example.com/class/function/id/, but can not be used to change the url in the address bar.

You will either need .htaccess for that (as you do now) or play around with redirect() (not recommended for your particular problem/feature/solution/...)
