Capital Boulevard was closed in both directions late Monday morning while Wake County sheriff's deputies and Raleigh police dealt with a person apparently having psychiatric problems in that area.
The state Department of Transportation said the road was shut down about 11:45 a.m.
Emergency Medical Services medics and firefighters had been dispatched to the area a short time earlier.
The incident was believed to involve a man on the Durant Road bridge over Capital Boulevard.
Never miss a local story.
Authorities had convinced the man to come off the bridge about 20 minutes after the incident began, they said.
