Air Force Officials said a "security incident" that closed the east gate at Peterson Air Force Base for more than an hour is now over.
Authorities said the closure was due to a tip about an explosive substance left near the gate, but they didn’t find anything after a search.
No one was hurt.
Multiple Colorado Springs Police cruisers were on Marksheffel Road directing traffic away from the gate while the search was underway.
All gates at Peterson are back open.
