The M2 Medway Bridge was brought to a standstill earlier this afternoon while police responded to reports that a person was on the bridge in distress.
Police received reports of concern for the welfare of the person just after 2.30 pm on Saturday afternoon.
Officers were called and the road was closed in both directions between J2 A228 Sundridge Hill, Rochester and J3 in Chatham.
A man was “dangerously close” to the edge of the busy motorway bridge.
Officers closed both sides of the carriageway as a precaution before detaining the man.
The road has now reopened and the man has been taken to seek medical help
