A towering, nearly 300-year-old tree at the University of Michigan is set to be moved — carefully — to make way for a school expansion.

It won't be moving far: A trailer scheduled to arrive next month will move the 65-foot-tall bur oak tree about 500 feet, and it'll stay on campus.

Still, it's a pricey move. Transporting the tree and surrounding ground, which combined is estimated to weigh up to 850,000 pounds, is expected to cost as much as $400,000.

The cost is included in the $135 million price tag for the donor-funded expansion of the university's Stephen M. Ross School of Business.

The Texas-based company taking on the project has moved trees for decades and says the bur oak has at least an 80 percent chance of surviving.
