An alternate entrance to the Great Park is now in place and will be through mid-November. This will not affect any ongoing or scheduled events. Please take Trabuco Road (which will become Great Park Boulevard on Aug. 1), off Sand Canyon Avenue between the I-5 and Irvine Boulevard, which will serve as the main entrance to the Great Park during the summer months. The usual entry point at Marine Way will be closed to allow for construction work for the future Marine Way extension. Trabuco Road, which also can be accessed off Jeffrey Road, is often used as an entrance to the Great Park, especially during major events such as last year’s U.S. Department of Energy Solar Decathlon.
