Drivers are being warned that one of the Tyne Tunnels will be closed this weekend.
The Northbound Tyne Tunnel will be closed to traffic on Saturday and Sunday.
Tunnel operator TT2 Limited is implementation of a contra-flow system between 8pm on Saturday and until 4pm on Sunday as a result of an training exercise.
Traffic from both North and South of the river will travel through the southbound tunnel.
The northbound tunnel is being closed for an emergency training exercise involving TT2 staff and the emergency services. Essential maintenance will also be carried out during the closure.
During this closure the tunnel will be closed to vehicles carrying abnormal loads - meaning vehicles in excess of 2.9m (9ft 6in) in width will not be permitted.
Stuart Sutton, Operations Manager at TT2, said: “In order to minimise disruption to customers the event has been scheduled at the weekend, because the number of drivers using the tunnel is approximately half of what it is on weekdays.
“Thanks to the investment which created the second tunnel, we are in a position to carry out this work with minimal disruption to customers who rely on the A19.
"We thank drivers in advance for their patience and understanding.”
