The Jurassic Mile is a disappointment.
From the end of Zone H in East Coast Park, you keep walking until you go past the NSRCC Sea Sports Centre, there the path forks into two: the Jurassic Mile leading to the airport, and the Coastal Park Connector leading to Changi Beach.
The Jurassic Mile path takes you to a road which you have to cross, then you follow the pavement along the road. It's still not the 'actual' Jurassic Mile, although you'll find some cardboard cutouts of cartoon dinosaurs along the way to guide you.
Eventually you'll reach the 'actual' Jurassic Mile, one side concrete wall, the other side a tall metal fence with some plastic statues of dinosaurs. And pre-recorded sounds of dinosaurs are being played.
There was a clusterfuck of cyclists, and bottlenecks occur when people gather around the dinosaurs to take photos and selfies.
The end of the Jurassic Mile takes you to the multi-storey carpark next to T4. You can take the buses at the nearby bus stop to get out of Changi Airport: bus numbers 24, 34, 36, 110. There is no shuttle bus to take you from T4 to T2/T1/Jewel.

So boring, plastic statues of dinosaurs.
