From the current terminus at Wilshire/Western, the Purple Line Extension will extend westward for about nine miles with seven new stations. It will provide a high-capacity, high-speed, dependable alternative for those traveling to and from Los Angeles’s “second downtown.” Section 2 of the three sections will deliver 2.55 miles of twin-bored tunnels and two new stations at Wilshire/Rodeo and Century City Constellation.

In January 2017, Phase Two of the project, which will extend trackage 2.6 miles (4.2 km) further to Century City, was awarded a $1.6 billion grant from the Federal Transit Administration, covering the majority of the $2.6 billion estimated cost of the project. On January 27, the Metro board awarded a $1.37 billion construction contract to a joint venture between Tutor Perini Corporation and O&G Industries, with construction scheduled to be completed by 2025.
