Het is ondertu en wel bekend dat EA er een gewoonte van maakt om uitbreidingen te maken voor hun games. Deze keer zijn ze echter wel erg vlug, want SimCity 4 ligt pas enkele maanden in de winkels en de eerste uitbreiding komt er al weer aan. Rush Hour gaat hij heten, en de focus zal veel meer liggen op de infrastructuur dan bij het origineel. Zo heb je keuze uit tal van nieuwe wegen, bruggen, treinen en veerboten, en zul je in je stad ook te maken krijgen met verkeersongelukken.For the first time, players will take charge of vehicles in their cities. Is the fire department stuck in traffic on its way to a four-alarm fire? Players will take direct control of the "hook and ladder" and pursue the quickest route to the blazing inferno. Players will also solve mi ions such as catching car-jackers and thwarting bank robbers to earn reward buildings and other vehicles. As players gain traction by fixing transportation problems and solving mi ions, they will watch their mayor approval rating soar and their Sim population grow! They will also be able to put their Sims on the move in new cars, ferries, helicopters, and zeppelins.

New to SimCity 4 Rush Hour are a variety of new bridge options and the ability to create a city based on a modern European building set. Players will also be able to add popular structures to their cities such as historic train stations, cla ic Americana road marks, or European tourist attractions. They can make their final mark as mayor and personalize their city by labeling street names, mountains, neighborhoods, and points of interest. Het is te hopen dat Rush Hour de vernieuwingen met zich meebrengt die opnieuw €30 moeten rechtvaardigen. Het hele persbericht met de eerste screenshots zijn te zien op ToTheGame.
