Measuring approximately 6.5 km x 1.5 km/4 mi x 1 mi (+/- 1,000 hectares/3,000 acres), PARK21 will be a large park. This opens up opportunities for introducing alternative transportation possibilities in the park. Bike or electric vehicle rentals offer business prospects once the public space design is complete. An aerial tramway or people mover could be introduced and become an attraction in itself.
