Queues of more than two hours have been reported by frustrated motorists.

This Friday has been an absolutely nightmare and we've been stuck in traffic for the last two hours and missed so much I can't even begin to voice my disappointment. So disappointing, RIAT.

The blue and red routes seem to be the ones most affected, with traffic at a standstill through Kempsford. Even the dedicated bus route is gridlocked.
