Northbound travel onto the A52 Clifton Boulevard slip is currently blocked due to a police disturbance.
The incident occurred on Thane Road roundabout, underneath Clifton Boulevard.
The resulting tailbacks are affecting Queens A453, back to Tottle Lane so finding an alternative route is advised.
Nottingham City Transport have announced that the disruption is affecting bus services as well, with the Navy 48 line seeing delays.
The Clifton Bridge North stop is no longer being serviced by the 53 and 54 buses.
