I would say the Balrog was lucky to have escaped their vigilance, but it was probably the Dwarves who were luckier.

I think Nerwen is spot on in her observation.
Anyways the entrances to tunnels under Moria probably wasn't situated near the gates or at the main travel rutes, the misty mountains is a massive mountain range and it should be no problem to find a desolate place.
