Commuters faced huge tailbacks on the Queensferry Crossing just hours after it reopened.

Vehicles began using the £1.35bn bridge early on Thursday morning following a week of opening celebrations.

Long delays were caused, with queues stretching back to the M90 at Masterton and Pitreavie.

Police were also called after several drivers were reported for using the bus lane on the bridge.

Traffic Scotland operator manager Stein Connelly said: "Demand for using the Queensferry Crossing when it first opened last week was very high.

"People were understandably coming to see the new bridge and this did lead to congestion.

"With the crossing reopening we would urge road users to plan their journeys. Traffic is likely to be very heavy and long delays are possible."

A 40mph speed limit is in place on roads around the bridge.

He added: "If you are commuting, check Traffic Scotland and @trafficscotland on Twitter for the latest information before you leave and if you are coming to the area to visit the bridge, we would ask that you do so when traffic is lighter.

"We have seen tremendous levels of interest in the crossing and we really appreciate people's patience as the new arrangements bed-in."

Inspector Peter Houston said: "We would advise members of the public who currently cross the Firth of Forth as part of their commute to think about disruptions to their journey and to allow for extra travel time as traffic levels adjust.

"Those who are travelling to the crossing for non-essential journeys are asked to consider very carefully the timings of their visit and whether their journey is necessary."

The Queen cut the ribbon on the 1.7 mile structure on Monday during its official opening ceremony.

Hundreds gathered for the ceremony while 50,000 people walked across the bridge at the weekend.
