Motorists who were caught up in traffic chaos when the off-slip from the M3 to the SSE Arena had been temporarily closed due to a build-up of traffic - are now moving.
A PSNI spokesman said the off-slip from the M3 to the SSE Arena has reopened.
The traffic chaos came on the night of the BBC Sports Personality of the Year awards ceremony.
Some 7,500 people are expected to pack into the SSE Arena for the star-studded ceremony.
Among the favourites to take the title are tennis star Andy Murray, 28, who helped make history by guiding Great Britain to their first Davis Cup victory for almost 80 years, and heptathlete Jessica Ennis-Hill, 29, who won her second world title in Beijing in August, just months after giving birth.
Others in the running include “king of the long jump” Greg Rutherford, who took gold at the World Championships, Formula One champion Lewis Hamilton, world road race cycling champion Lizzie Armitstead and runner Mo Farah, who also enjoyed success in Beijing, winning his third successive 5,000m world gold medal.
