Hello, Siyuwj! Welcome to Wikivoyage.
To help get you started contributing, we've created a tips for new contributors page, full of helpful links about policies and guidelines and style, as well as some important information on copyleft and basic stuff like how to edit a page. If you need help, check out Help, or post a message in the travellers' pub. If you are familiar with Wikipedia, take a look over some of the differences here.
Thank you for plunging forward and contributing! However, when an article already has a pagebanner, please do not unilaterally replace it. Instead, make a proposal on the article's talk page and wait for a consensus. In this instance, I think the bridge is much more distinctive than yet another skyline.
All the best,
