Another problem on the Forth Road Bridge has delayed its full reopening by up to a month.
Engineers have discovered an issue on the south tower, which is related to movement of truss end links.
While it will not cause another breakage - like the crack on the north tower did in December - work is required to strengthen it.
Full reopening has now been pushed back to mid-March, a month later than the original estimate of mid-February.
Phased reintroduction of HGVs has begun, with up to 600 HGVs allowed on the northbound carriageway between 11pm and 4am every night.
Traffic signals will release HGVs on to the bridge at a rate of one every 30 seconds, subject to weather conditions.
Storms have slowed the progress of the original repair work, and work to fix the latest issue is expected to be even more weather-dependent. This is because it is to be carried out above the carriageway on mobile platforms which are more susceptible to wind, so full reopening could be pushed back even further.
