Drivers faced delays of nearly half an hour on the M90 at the Fiarton Bridge after a lorry fire on Thursday.
Two crews from Perth were called to the fire at around 4.30am.
The bridge was shut at the height of the fire and one southbound lane remained shut until just before 11.30am.
That caused delays of nearly half an hour for drivers heading south.
The lane has now been cleared.
