All lanes are now open again on the westbound carriageway of the Prince of Wales Bridge.
Earlier the fire brigade attended reports of a lorry fire at the start of the bridge near junction 22.
Crews from Avonmouth and Temple fire stations attended the scene.
Although there was no fire, the lorry required repairs which resulted in the temporary lane closure.
