Travel Tips for the U.S. 101 Deck Replacement Project

April - May 2020

UPDATE: Caltrans has accelerated the project timeline because of lower traffic volumes due to the shelter-in-place order. Construction now begins on 4/25/2020 (originally 7/7/2020).

The Project

Alemany Aerial

Caltrans will demolish and  rebuild a segment of the deck of Highway 101 at Alemany Circle, just north of the interchange with I-280. Traffic will be severely impacted in both directions. Expect speed reductions, lane reductions, and rerouting of all traffic onto city streets. For more details, click here.
