The victim of a hit and run crash at Holden Hill remains in a critical condition as police appeal to the public to track down a driver allegedly involved in the horrifying incident.

Just before 4.15am on Tuesday, emergency services responded to a collision between a dark-coloured SUV and a pedestrian on Sudholz Rd.

The pedestrian, a 25-year-old man from Mitchell Park was treated at the scene before he was taken to the Royal Adelaide Hospital, where he remains in a critical condition.

The driver of the vehicle failed to stop.

Major crash investigators visited the scene and examined shattered debris scattered across the road. Lying among the debris was a watch.

Witness Gurdeep Singh was travelling closely behind the suspect.

“I noticed an SUV had rolled over something, so I thought it was rubbish or something,” he told 7NEWS.

“When I got closer, I saw a guy was lying on the road.”

Mr Singh pulled over and rushed to the victim’s aid.

“That car was just in front of me, so I thought he would also come out and try to help, but when I got out, he just took a U-turn and ran away,” Mr Singh said.

The victim was treated by paramedics before he was taken to the Royal Adelaide Hospital, where he remains in a critical condition.

“He had a big cut on his eye and his teeth were out, he was bleeding from the mouth … I asked him if he was all right, he said no,” Mr Singh said.

Police condemned the driver’s actions: “That person was left there and we will make every effort to find the driver of that vehicle,” Deputy Commissioner Linda Williams said.

“It’s appalling that you could leave a person on the road in such a condition then just drive off. It’s so reckless and so indifferent to that persons safety.”

Two of the three lanes of Sudholz Road were closed near the intersection of North East Rd and authorities asked motorists to avoid the area.

As of 11am, all lanes had reopened.

Anyone with information about the crash is asked to contact Crime Stoppers on 1800 333 000.

Meanwhile, another man remains in hospital with life-threatening injuries after a smash at Middleton.

Just before 3.30pm on Monday, a car left the road and collided with a tree near the intersection of Michelmore Rd and Airport Rd, Middleton. The Fleurieu man was stuck in the car and has sustained serious leg injuries. He was flown to Flinders Medical Centre and police said his condition was considered life-threatening.
