Three vehicles were involved in a crash on the A329m this morning.
Thames Valley Police said that one lane was closed as a result.
The reason is that there is a large diesel and oil spillage on the carriageway. This has now been cleared sufficiently to enable the road to reopen fully.
Highways England will be coming to the site to sort out the incident, which took place on the A329m between Winnersh Triangle and the M4 junction towards Bracknell.
No one was injured in the accident although a picture tweeted by the police show that airbags had been deployed and the front of one of the cars had been wrenched open during impact.

#A329M is now fully reopened as lane 1 has been adequately covered in dress and dry by Highways to soak up the oil / diesel. #P5562 https://t.co/5Ytsec40YI
