Work crews removed a dozen Eucalyptus trees and one palm tree along Morena Boulevard Saturday to make way for a new trolley line expansion.
The Mid-Coast trolley project will connect University City to Old Town.
The project is expected to be completed by 2021.
After construction is finished SANDAG says trees and other vegetation will be planted along Morena Boulevard.
The trolley expansion will notably serve the VA Medical Center and UC San Diego.
