The Starfleet construction yard in the Iowa countryside where the USS Enterprise of the Kelvin timeline takes shape and where James Kirk boards a recruit shuttle in 2255.
Riverside Shipyard is a Starfleet facility near the town of Riverside, Iowa, in the alternate reality of the 2009 film Star Trek. Unlike the orbital yards usual in other productions, it assembles a starship on the ground, and the unfinished USS Enterprise stands there among scaffolding and floodlights.
After a bar fight with Starfleet cadets in 2255, the aimless James Kirk is challenged by Captain Christopher Pike to do better than his father. He rides his motorcycle to the yard at dawn, looks up at the ship, gives the bike away to a worker and boards the shuttle for new recruits, telling Pike he will finish the Academy in three years.
On that shuttle he meets Leonard McCoy. The film's first teaser trailer also showed welders at work on the ship's hull.
