Best terminal location (proposed)
the El Cajon Transit Center district (Trolley Orange/Green lines). El Cajon's transit center is the East County hub where two Trolley lines meet, with downtown's Main Street corridor alongside. The city is the densest part of San Diego's east county. It captures the entire East County catchment from La Mesa to Alpine.
