Exit number = Route number

That would be a fun one to include in directions - "Then get off exit 414 for 441 and 41...."

Tangential but I'll mention it.

In north-central PA, generally north and west of Williamsport, there is a PA 14,  PA 44, PA 144, and a PA 414 in the same general area.

PA 41 and 441 also exist, but they are well south of there, in the SE portion of the state (where I define SE as south and east of Harrisburg).
