There was a huge traffic snarl-up along Nairobi’s Waiyaki Way after an accident occurred at the entrance of the Nairobi Expressway in Westlands on Wednesday.

Eyewitnesses said a Super Metro passenger bus overturned after it hit a guardrail while evading hitting another vehicle that was using the expressway lane.

Several passengers were left with scores of injuries and rushed to the hospital.

The accident happens, barely two days after an Embasava Sacco bus was involved in another accident at Mlolongo toll station.
