Motorists faced tailbacks up to 12 miles long on the M74 today as roadworks caused major delays.

Drivers faced disruption and queues of around an hour as the major roadwork improvement project continued.

Tailbacks were particularly bad between Junction 8 Canderside and Junction 4 Maryville.

Average speed cameras have also been introduced on the northbound and southbound carriages between Junction 6 Hamilton and Junction 3A Daldowie.

They will remain in place until 2017 to allow for the construction of a new lane and hard shoulder along this stretch of the motorway.

Average speed cameras were first used in Scotland during roadworks on the M74 in 2006, but were used more recently during upgrades to the M80.

The cameras will also be rolled out on stretches of the M73, M8 and A8.

It comes as work on the M8 M73 M74 Motorway Improvements Project is ramped up.
