Ever onward, upward, outward. Who knows the price tag of Mayo’s next expansions. At this day-dreaming point, budget isn’t the issue.

Breaking news: A peek at Mayo’s 15-year self-image

ROCHESTER, Minn. – Mayo Clinic has a 15-year master plan with new skyscrapers that would dwarf existing buildings and change Rochester’s skyline. News reporter Andy Brownell of radio station KROC posted a photo of a table-top mock-up of the development. Brownell came by the mockup from anonymous sources. Much of the multi-billion dollar expansion would require razing existing structures in a five-block area adjacent to the current campus. The plan includes:

> New hospital. On the site of Mayo’s Ozmun Building, which once was the Olmsted County courthouse.

> Twin towers. These would rise 10 stories higher than the 21-story Gonda Building, the main patient entry.

> New labs. A 15-story tower overing an entire block and replacing current Baldwin pharmacy building.

> Parking. Two new parking ramps would replace the Damon parking ramp and the current Mayo medical sciences building.

Five square blocks. Mayo’s futurologists have more pedestrian subways and skywalks to connect it all.
