By The Numbers: How $2.4 Billion in Transit Projects Are Reshaping San Francisco's Future

San Francisco's transformation into a modern transit hub is playing out in spreadsheets and construction timelines as much as in steel and concrete. New figures released by the Metropolitan Transportation Commission paint a portrait of a city betting billions on its future connectivity—with mixed results so far.

The Central Subway extension, the city's most ambitious transit project in decades, has consumed $2.3 billion to extend light rail service from Union Square through Chinatown to Fisherman's Wharf. The project, originally budgeted at $1.6 billion when planning began in 2006, represents a 44 percent cost overrun—a figure that tracks with national infrastructure inflation trends but has strained municipal finances nonetheless. The line, now operational since 2022, carries approximately 23,000 daily riders, falling short of the original projection of 31,000 daily trips by this point.

Meanwhile, the Geary Rapid Bus Corridor initiative offers a contrasting narrative. At a cost of $240 million, the dedicated bus lanes stretching 8.5 miles from Market Street to the 48th Avenue terminus have increased average bus speeds by 31 percent during peak hours—from 9.2 mph to 12.1 mph—according to Muni's latest operational data. Ridership on the Geary line increased 18 percent in the first two years of operation, suggesting that more modest infrastructure investments can yield measurable returns.

The Bay Bridge tolling structure, meanwhile, reveals how pricing mechanisms influence movement patterns. Since congestion pricing on weekday mornings began in March 2025, vehicle crossings during 6-10 a.m. dropped 12 percent, while toll revenue generated $847 million in the first fiscal year—exceeding projections by $127 million. Transit agencies have funneled 40 percent of that surplus into expanded ferry service and BART late-night operations.

Perhaps most telling is the real estate mathematics underlying these investments. Properties within a quarter-mile of the Central Subway's Civic Center station appreciated 22 percent between 2019 and 2025, compared to an 11 percent citywide increase—underscoring how infrastructure investments create wealth concentration alongside mobility benefits.

As San Francisco enters another phase of transit planning, including proposals for a second Transbay crossing and expanded cable car service, these numbers suggest the city's leadership must balance ambition with fiscal realism. The data tells a story of infrastructure that works, but often differently—and sometimes costlier—than planners anticipated.
