A construction worker was injured Thursday afternoon in a fall at Fermi National Accelerator Laboratory in Batavia.
The person was working in the Proton Improvement Plan-II area. The Fermilab Fire Department first treated the worker, who then was flown to a trauma center, according to a Fermilab spokesman.
The worker was employed by a contractor.
Ground was broken in April at the PIP-II site for the construction of a particle accelerator.
