SAN FRANCISCO (AP) - The construction of a $1.6 billion subway through San Francisco's Chinatown has reached a milestone.
The San Francisco Chronicle reports that crews finished digging the tunnel for the Central Subway earlier this month. John Funghi, the subway's project manager, says the excavation was completed on time and within budget.
The 1.7-mile subway will connect the city's South of Market and North Beach neighborhoods.
Next up is station construction and the installation of tracks, overhead wires and electronic systems.
Train service through the tunnel is expected to start in 2019.
