SANDAG began the design, environmental, and permitting process in 2009. The construction contract was awarded in May 2012, active construction began in late 2012, and the crossovers were completed in October 2013. 


The total cost of the project is estimated at $11 million. Approximately $9.8 million came from federal sources, including $8.4 million from the American Recovery and Reinvestment Act. The Caltrans Division of Rail provided $0.5 million for the project’s design from Prop. 116, the Clean Air and Transportation Improvement Act. SANDAG leveraged these funds with $0.7 million from TransNet, the voter-approved half-cent sales tax for regional transportation improvements.
