An IT glitch yesterday brought the traffic flow on King Fahd Causeway to a standstill, according to Al Riyadh newspaper.
The technical fault, which was reported at 6.50pm, caused long tailbacks.
The IT system was restored to the passports section at 7.20pm thanks to the intervention of the National Information Centre, said Eastern Province Passports spokesman Colonel Ma'ala Al Otaibi.
Similar glitches also disrupted traffic movement at the Khafji and Al Raqai entry points.
