The Metro ExpressLanes project is a transport project in Los Angeles County, California that debuted in 2012 to "improve traffic flow and provide enhanced travel options on I-10 and I-110 in Los Angeles County".
It includes a range of infrastructure developments on the Harbor Transitway and the El Monte Busway.
In addition, new vanpool vehicles and buses will be purchased.
The budget was $290 million and construction, which began in 2011, was completed in February 2013.
Some transit improvements for the Metro J Line are still being worked on.
