Discuss I-880/29th Avenue/23rd Avenue Interchange Project Update
Background
The I-880/29th Avenue/23rd Avenue interchange project in Oakland implements operational and safety improvements on I-880 at the existing overcrossings of 23rd and 29th Avenues. Improvements include replacement of the freeway overcrossing structures, improvements to the northbound on and off ramps as well as to the freeway mainline. A soundwall will be constructed in the northbound direction between 29th and 26th Avenues, and the project includes modifications to local streets and landscaping enhancements.
The total project cost is currently estimated at $114 million. The majority of the funding - $80 million - is from the Trade Corridor Improvements Fund (TCIF) of the Highway Safety, Traffic Reduction, Air Quality, and Port Security Bond Act of 2006, which was approved by the voters as Proposition 1B in November 2006.
The construction phase of the project began in 2014. Construction completion is expected in 2019. The project is being led by Caltrans and the Alameda County Transportation Commission (Alameda CTC). Caltrans and Alameda CTC staff provided an update to the Transportation Commission in March 2014 and in November 2016, and this agenda item represents the third update.
