Recent studies show a route through Crest Canyon is the highest rated of five potential choices for a railroad tunnel that would take the railroad tracks off the eroding coastal bluffs in Del Mar.
Other possible underground routes include one along Interstate 5, one beneath the street of Camino Del Mar though the city of Del Mar, and two more through Crest Canyon, according to a conceptual analysis by the San Diego Association of Governments and its consultants.
SANDAG, North County Transit District and other local agencies have talked for years about moving the tracks off the bluffs, but only recently have the agencies received grant money for the preliminary studies required. Construction alone is expected to cost $3 billion or more.
