If you are someone who lives in the UK and regularly travel on the motorway, I can understand how frustrating it can be when you discover that there are mile long jams caused by some repair work or an accident. Even if you don't travel up and down the motorway regularly and venture on to the motor ways occasionally, you might want to check out the following sites below:
1. Frixo, a road / motorway traffic reporting site which is updated every 3 minutes via feeds from various sources.
2, My Way, a joint initiative between RAC and Expedia, which provides alternative routes to some of the UK's worst congestion hotspots.
