VIA says delays at the Fallowfield crossing in Barrhaven Tuesday afternoon were caused by a safety measure in an instance they don't classify as a malfunction.
One of the gates did not go completely vertical.
A VIA spokesperson says when that happens, the lights continue to flash and the bell continues to ring as a precaution.
The delay held up traffic from approximately 4:45 to 5:00.
It's unclear what caused the problem, as VIA says it's possible something physically obstructed the gate as it rose.
They're apologizing to anyone who was inconvenienced.
