Police are investigating after the body of a man was discovered on one of Cardiff's busiest roads.
South Wales Police said the man appears to have fallen from the flyover at the Gabalfa flyover on Western Avenue in the early hours of this morning.
A force spokesman said: "The deceased was wearing a cream jumper and red t-shirt, blue jeans and black shoes and may have walked towards the flyover from the direction of Canton.
"Police officers are appealing for any witnesses who may have been driving across or beneath the interchange between 4:00 am and 5:00 am."
Motorists attempting to enter or exit the city are currently facing long delays due to the incident on the A48.
The road remains closed for the forseeable future and motorists are encouraged to take an alternative route, police added.
Looks like a really serious incident on Western Avenue under the Gabalfa flyover. Police everywhere, doesn't look like it's opening soon...

Wales Online reports that despite the closure at the interchange, the Gabalfa flyover remains open.
A diversion has been put in place onto the interchange to re-route drivers back onto Western Avenue, but traffic is reportedly building up along the A4119.
The BBC reports that traffic is currently queuing for four miles.
