It is expected to attract 8.5 million visitors annually, with 55,000 visitors on peak days, making it one of the most visited theme parks in Europe.
Due to the scale of the project, which included upgrading local roads and rail links, Universal required a Special Development Order (SDO) before it could start construction.
Universal has claimed it will generate nearly £50bn of economic benefit and create 28,000 jobs.
In June, a form was added to the Universal UK website for people to register interest in “future job opportunities”.
About 2,000 suppliers have also expressed interest in working with the park.
