A four-car bumper-to-bumper crash inside one of the Santa Venera tunnels brought northbound traffic to a crawl on Wednesday morning, with long delays stretching all the way back to Marsa.The collision happened just before 8.45am and quickly caused major congestion during peak rush hour, after one of the already-busy lanes had to be closed.Drivers heading north were left stuck in a growing tailback that kept building as the morning went on.A woman was taken to hospital with what are believed to be slight injuries.If you’re heading in that direction today, expect delays, especially along the Marsa approach and surrounding arterial routes, as traffic slowly clears.Were you stuck in traffic this morning?•
