A motorcyclist has fallen to his death after losing control during a high-speed race and being flung off a Melbourne bridge.
The 32-year-old Highett man died about 10pm on Sunday after travelling south over the Bolte Bridge at Port Melbourne and taking an exit ramp where he crashed into a barrier, and was thrown over.
Detective Inspector Stuart McGregor told Nine News on Monday the pair had been racing for many kilometres before the crash and had been travelling at speeds up to 200km/h.
"People see these roads as race track. They're not race tracks. They're are not built for race tracks ... (or) being able to travel at high speeds," he said.
Investigators want to speak to the rider of a second motorbike who was seen driving alongside.
"The fact he left someone on the side of the road dying means we need to get him off the road. There was an agreement to travel in a dangerous manner," Det Insp McGregor said.
Police are also appealing for dashcam footage of the crash or the preceding reported race.
Later on Monday, a woman driving a Winnebago was killed when the vehicle veered off the Great Alpine Road and crashed into a tree at Eurobin.
