Use of Local Aggregates

Rock mined from Azusa Rock and Irwindale has been used to build the most iconic buildings, highways and bridges in the greater Los Angeles area. Projects built using aggregates from the San Gabriel Valley include the Arroyo Seco Bridge, Los Angeles City Hall, Pacific Coast Highway, Riverside Drive, Los Angeles Memorial Coliseum, and the Hollywood Bowl.

More recently, in February 2014, Vulcan Materials Compnay provided 100% of the construction aggregates used to build the foundation for the new Wishire Grand Hotel - which received the Guinness Book of World Records record for the largest continuous concrete mat pour. The majority of the construction aggregates for the pour came from the Vulcan Materials Company's Reliance Facility on Foothill Boulevard.
