Congestion is causing some delays on the M25 this morning.
Drivers are also being warned to expect delays during peak times for the next few weeks as roadworks begin on some parts of the carriageway.
Rail services are now running on time, according to Southern Rail, after earlier signalling problems and an operating incident caused some delays and passengers from Oxted had been warned to expect delays while a tree was removed from the line at Sanderstead, but that has since been cleared.
