The last full weekend closure of San Francisco's Hospital Curve repaving series is now under way. Caltrans closed all southbound lanes of the U.S. 101 Bayshore Freeway between 17th Street and Cesar Chavez Street at 11 p.m. on Friday, November 6, and the lanes are scheduled to reopen at 6 a.m. on Monday, November 9. Crews will use the weekend to repave the remaining two southbound lanes — the final piece of a repaving sequence that began on the northbound lanes in September and continued with two southbound lanes in October.

For the whole weekend, motorists have no access to the 4th Street, 7th Street and 10th Street on-ramps, and the westbound I-80 to northbound 101 Central Freeway connector is also closed. All northbound lanes remain open for public travel. Caltrans is advising drivers to avoid southbound 101 at Hospital Curve altogether because of anticipated delays, and to use southbound I-280 as the alternate route; its detour map also routes traffic via the 5th Street and 8th Street exits to Harrison Street and on to I-280, with Guerrero Street and South Van Ness Avenue as secondary options.

This is the fourth and final closure weekend in the series: the freeway stretch had already been closed on three previous weekends over the last two months, local coverage of the Caltrans announcement noted. The immediately preceding San Francisco freeway closure in the programme — the westbound I-80 Bayshore Freeway weekend of October 23 — finished ahead of schedule, with lanes reopened at 3:32 a.m. on Monday, October 26, according to Caltrans.

A rehabilitation project that began in fall 2025

The weekend's work completes the repaving, but it sits inside a broader U.S. 101 Bayshore Freeway (Hospital Curve) rehabilitation project that began in fall 2025. Hospital Curve is one of Caltrans' four 'Fab 4' San Francisco rehabilitation projects, alongside the Central Freeway (US-101), the entire 19th Avenue (SR-1) repaving and the I-280 Farallones pedestrian overcrossing. Caltrans says the programme is restoring structural integrity and safety on the city's most-used freeways, on which approximately 44,900 people travel daily, and that the Hospital Curve repaving is expected to preserve the 101 corridor for the next 40 years.

For freight and trucking, the Bayshore is the surface link between San Francisco, the Peninsula warehouse belt around South San Francisco and Brisbane, San Francisco International Airport and the Silicon Valley corridor beyond. A full southbound closure pushes that traffic onto I-280 — the route Caltrans itself recommends — and onto city streets around the closed ramps, so dispatchers running weekend loads out of the city should expect slower turns and plan fuel and hours accordingly. There is no separate truck ban in the advisory; the closure applies to all southbound traffic equally.

The closure also lands on the first weekend after the midterm elections, in a city where many Punjabi and South Asian families live and work across San Francisco, Daly City and South San Francisco — a corridor where weekend trips to family, gurdwaras and Peninsula workplaces overwhelmingly run on either the 101 or the 280. Caltrans' advice is simple: take the 280 southbound, and leave extra time.

What happens next

If the work stays on schedule, all southbound lanes reopen at 6 a.m. on Monday, November 9, in time for the morning commute, and the Hospital Curve repaving is finished — no further full weekend closures are listed for this stretch in the series. Caltrans stresses the work is weather dependent, so a wet weekend could still change the timing. The wider Fab 4 rehabilitation continues elsewhere in the city, including the Central Freeway work and the I-280 overcrossing project, and drivers should keep checking Caltrans advisories before weekend trips.

Awaaz Punjab will note the reopening — on time or otherwise — in its California coverage. Readers driving the corridor this weekend can check live conditions through Caltrans QuickMap before setting out.
