This project proposes to construct operational and safety improvements on I-880 at the existing overcrossings of 23rd and 29th Avenues in the City of Oakland. Improvements include replacement of the freeway overcrossing structures, safety improvements to the northbound on and off ramps as well as the freeway mainline. A soundwall will be constructed in the northbound direction between 29th and 26th Avenues.

Construction activities have begun and will continue through summer 2018.
