Of course, not sure what tunnels you are referring . Necho Allen Hotel was on the corner of Centre and Mahantango. Norwegian Street was the next street to the north of Mahantango. Are you referring to the Yuengling Ice Cream plant is essentially located between Mahantango & Norwegian streets and Fourth & Fifth Streets. Ice Cream plant is across the street from the brewery and currently houses the gift shop and museum; it is also used for water treatment and storage. There maybe tunnels between the two buildings.
