Here's information provided by the City of Livermore:
The new West Jack London Boulevard Extension between SR 84 (Isabel Avenue) to El Charro Road is now open for traffic. West Jack London Boulevard will provide access to the New Paragon Outlet Mall from Livermore when it opens on November 8, 2012. The new Livermore to Pleasanton Trail adjacent to West Jack London Boulevard will be completed by the end of November 2012.
West Jack London Boulevard was built under the El Charro Specific Plan Infrastructure construction project by Ghilotti Construction Company. The total contract amount for the El Charro Specific Plan Infrastructure Project cost approximately $20 million. The extension of the West Jack London Boulevard is a two lane road, approximately 2 miles long, and includes the construction of the vehicular bridge over the Arroyo Las Positas, and a flood conveyance culvert that connects between the Las Positas Golf Course to a new Flood Conveyance Facility west of the roadway. The new West Jack London Boulevard will provide an alternative access to the Paragon Outlet Mall from Livermore without the use of I-580.
Mayor Marchand emphasized that improving transportation infrastructure is a critical need in the City. “This segment will play a vital role in reducing congestion on I-580 and help ease the time it takes residents to get to the Paragon Outlet mall.” Marchand said.
