There is one parcel there where the address is lane all of the rest are street. The transportation layers show both street and lane with functional class and operations consider it lane. The all roads layer has street. The city shows it as street. The county is the official record of home addresses so I'd say at least that one house is addressed as lane, the rest are streets. The city probably assigned the address to the parcels and the country just hold the records.  The city is probably the creator record of the street names and it says street.  I don't know who maintains the address database for 911 there but that should be a clone of the official records.  The sign shop can make typos so you can't rely on signage.
