Question:
I'm aware that there are some streets in Tiveria which have meisim buried underneath them. Is it mutur to take a bus which drives over these streets?
Answer:
Generally that is correct, kohanim should be careful not to go over streets that are build over buried bodies. If you have a specific question, I would advise you to call R' Lumbard at 054-292-0903.
Best wishes
