The Alameda County Transportation Commission (Alameda CTC), in cooperation with the California Department of Transportation (Caltrans) and the City of Hayward, will implement improvements at the Winton Avenue and A Street interchanges along the Interstate 880 (I-880) corridor.
The I-880 Interchange Improvements (Winton Avenue/A Street) (Project) proposes to provide interchange and local road improvements along I-880 from 0.1-mile north of the I-880/A Street Interchange to 0.4-mile south of the I-880/Winton Avenue interchange. Improvements include interchange on- and off-ramp reconfigurations, signal modifications, local roadway restriping, and bicycle and pedestrian improvements to improve traffic operations, safety and accessibility, in the City of Hayward, in Alameda County.

The I-880 Interchange Improvements Project aims to reconfigure the interchanges at Winton Avenue and A Street and implement complete streets features. The project intends to improve traffic operations, safety, and accessibility to the retail and commercial land uses at Winton Avenue and A Street. The project will also implement bike lanes and pedestrian friendly design at both interchanges, modify signals and reconfigure intersections to improve traffic flow, and improve weaving operations along the segment of I-880 between the Winton Avenue and A Street interchanges.
The California Department of Transportation (Caltrans), in cooperation with the Alameda County Transportation Commission (Alameda CTC) and the City of Hayward (City), proposes to provide interchange and local road improvements along Interstate 880 (I-880) from 0.1 mile north of the I-880/A Street Interchange to 0.4 mile south of the I-880/Winton Avenue Interchange. The I-880 Interchange Improvements Project (Project) would include interchange on-and-off-ramp reconfigurations, local roadway restriping, and bicycle and pedestrian improvements in the City of Hayward, in Alameda County, California. Caltrans, as the California Environmental Quality Act (CEQA) and National Environmental Policy Act (NEPA) lead agency, has studied the potential effects that the proposed improvements may have on the environment. The results of these studies are summarized in an Initial Study (IS) with Proposed Negative Declaration, also referred to as the Draft Environmental Document (DED). This project is subject to and complies with the requirements of both the CEQA and NEPA. In an effort to protect public health and increase public participation and accessibility, Caltrans and Alameda CTC hosted a virtual meeting on Wednesday, June 15, 2022 to watch a live presentation about the project and the environmental review process, pose questions, and provide formal comments on the DED.
