Schedule changes
The ALMS held its first-ever event in the Northeastern United States with an Independence Day weekend event at Lime Rock Park.[3] The series will also return to Portland for the first time since 2001, as well as return to Mid-Ohio, which was dropped after the 2002 season. Trois-Rivières was dropped after new Quebec anti-tobacco legislation made holding the race unfeasible. Mosport became the only race outside of the United States. Miami was also dropped from the calendar after the CART Series collapsed at the end of 2003. The Grand Prix of Atlanta was dropped as it was only introduced as a replacement for cancelled races. Laguna Seca would hold the season finale and had its distance increased to 4 hours.
