There was traffic chaos in the CBD on Thursday after a truck became wedged under a bridge.

The vehicle became stuck under the rail bridge at the corner of Flinders Street and Spencer Street.

All lanes have since re-opened to traffic, but commuters should expect delays when using trams.

The 12, 96, 109, 70 and 75 tram lines are all impacted.

“We’re hearing it could still be a few hours before trams get back to normal,” Andrew Crook, from the Department of Transport, told 3AW Drive.
