Premium Content Subscriber only Motorists were urged to take care driving through Brisbane and the Sunshine Coast hinterland on Wednesday morning as a thick fog covered the region. The weather bureau issued a warning for the Brisbane area just before 6am, saying reduced visibility in fog would “make road conditions dangerous” during the morning. There were heavy delays southbound on the Bruce Highway with traffic backed up from North Lakes to Burpengary following several crashes, with a trip from Caboolture to Brisbane estimated to take 90 minutes. Forecaster Rosa Hoff said it was a similar story for the Sunshine Coast hinterland and Gympie but the coastal strip was mostly clear.
