Why is it measured from sea level?

How else would you measure it? You need a reference point.

Geez idk, maybe just telling us how tall it is?

If you ask how tall my house is, should I just tell you it sits a 449ft above sea level?... Or I could just tell you it's 30ft tall.

Also, the title is incorrect. The bottom of the Huajiang Canyon is already at 300-400 meters above sea level. What they mean to say is the bridge measures 625 meters tall (from lowest point to the deck).
