Port Tunnel to close between Wednesday night and Thursday morning

The Port Tunnel is to close on Wednesday night for seven hours.

Both lanes of the underpass will be shut from 10pm on Wednesday night to 5am on Thursday morning.

Operators said the closure is due to scheduled maintenance which occurs when necessary.

Last month traffic chaos was caused after a truck burst into flames in the tunnel and it was temporarily shut.

Gardai immediately lifted the 5-axle ban for Dublin City Centre which pushed hundreds of heavy goods vehicles into commuter routes.
