The elevated bike path runs about 7.5km and is an excellent piece of infrastructure. Away from car traffic it sits between the road on the ground level and the elevated public transport track. It has separate paths for pedestrians and bikes, although you still find quite a number of pedestrians on the bike path (because it gets more shade from the road above).
The track is not for racing, but fun to ride at a recreational speed. But be on the lookout at the entrace/exit points. The bike lane will have barriers to swerve around to slow you down.
