Touchstones Nelson is proposing to put a tunnel between its basement and the Gray Building next door.
They’ve already leased the so-called Diefenbunker as a new home for their artifact collection.
Executive director Astrid Heyerdahl says physically linking the buildings would have several advantages.
Heyerdahl says a feasibility study has found that it can be done.
They’re applying for provincial and federal grants to make it happen.
