In fall 2014, the Mid-Coast Trolley Extension project received its final environmental clearance from the SANDAG Board of Directors and the Federal Transit Administration (FTA). In September 2016, the FTA signed a Full Funding Grant Agreement with SANDAG to provide the 50 percent federal funding match needed to begin construction in fall 2016. The other half of the funding is provided by TransNet, the San Diego region’s voter-approved half-cent sales tax for transportation improvements. Including financing, the budget for the project is approximately $2.17 billion.  

Pre-construction activities – consisting of the relocation of utilities out of the project alignment – began in early 2016, and primary construction activities began in October 2016. Construction reached its halfway point in spring 2019. The Trolley extension opened for revenue service on November 21, 2021, on time and on budget.
