You don't need to know anything about engineering or building to appreciate a structure like Goodwill Bridge. Stop for a moment and take in the craftsmanship and design on display.
You're spoiled for sightseeing choice in Brisbane Central Business District. Goodwill Bridge is a great place to kick off here, but there are loads of other fine spots to consider. Suncorp Stadium, Roma Street Parkland, and The Gabba are near the modern structure and will round out your day nicely.
