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. The existing high-occupancy lanes on these transitways were converted to high occupancy toll (HOT) lanes. Associated works included a major upgrade to El Monte bus station, expansion of Metrolink's Pomona Station, the creation of a new transit station at Union Station and increased park and ride capacity and bike lockers at many transit stations. In addition, new vanpool vehicles and buses will be purchased. The project was delivered by the Los Angeles County Metropolitan Transporta
