The FAB-4 Rehabilitation Projects

What are they? They are four major freeway and road rehabilitation projects that will rehabilitate the integrity of structures and restore the safety of San Francisco’s most trafficked arteries.  Included is the 19th Avenue repaving project starting in summer 2025; the US-101 rehabilitation at Hospital Curve starting fall 2025; the Central Freeway/1-80 Bayshore Bridge project starting in spring 2026, and the I-280 pedestrian overcrossing rebuild located at Cayuga Park starting in 2027. Learn more about these exciting projects at www.sfhighwayprojects.com.

Presidio Parkway Marks 10 Years!

A decade ago, Doyle Drive was transformed from an aging, earthquake-vulnerable structure into the safe, beautiful, and resilient Presidio Parkway—a stunning gateway to San Francisco.  Next month the people who made this project possible will convene for a 10-year Anniversary celebration at Presidio Tunnel Tops. Project partners, public officials, and community members will attend.

Featured speakers include Toks Omishakin, Secretary of Transportation for the State of California; Speaker Emerita Nancy Pelosi, and Senator Scott Wiener.

Informational booths, exhibits and the original project model will be displayed to accent a festive day of remembrance!


Smooth Roads Ahead for 19th Avenue!

Get ready, 19th Avenue (State Route 1) neighbors, students, and commuters! Caltrans is kicking off a major repaving project starting in the summer of 2025 to give this vital corridor a much-needed refresh. Stretching from Golden Gate Park (Lincoln Way) to San Francisco State University (Holloway Avenue), this project will upgrade nearly 19 lane miles—including the busy Park Presidio and California Street intersection.Why does it matter? Whether you’re a student heading to class, a local running errands, or a shopper visiting neighborhood stores, smoother roads mean safer, more comfortable trips for everyone.

Work will be rolled out in two phases: repaving the parking strips is scheduled to begin in August 2025, followed by full lane resurfacing in the Spring of 2026. Construction happens on weekdays, with at least one lane open in each direction to keep traffic moving—though commuters should consider alternate routes during rush hours (6–10 AM, 3–7 PM).

Better roads are on the way!


Increased Efforts for San Francisco Unhoused Residents

Caltrans and the City of San Francisco are working together on a new, street-level initiative to provide real-time responses to the needs of the city’s unhoused population. This collaborative effort aims to address mental health crises and other emergencies with greater urgency, coordination, and compassion. Recognizing the growing need for responsive and humane support, the partnership brings together transportation and city resources in a unified approach. By focusing on high-need corridors and neighborhoods where Caltrans' right-of-way intersects with city streets, teams can reach individuals more quickly and efficiently.


I-280 Bridge Ramp Work Near Finished

Significant progress is being made on the I-280 Highway Maintenance Bridge Project. Despite wet weather delays, the work crew is nearing completion of the ramp rehabilitation project and plan to wrap up on schedule by summer 2025. Launched in October 2024, the project spans seven key locations along a 10-mile stretch of the I-280 corridor. The goal: to extend the life and safety of six aging bridges through critical maintenance work, including polyester concrete overlays, joint seal replacements, and asphalt repairs.

All work has been taking place overnight to minimize daytime disruptions, though full ramp closures have been required during active construction. Crews began at the Lyell Street undercrossing and are progressing one bridge at a time.

As the project enters its final phase, motorists can look forward to smoother, safer freeway access throughout the I-280/US 101 interchange and beyond. Stay tuned for updates on the remaining locations and detour information.
