Welcome to the State Route 239 Project environmental scoping open house. The California Department of Transportation (Caltrans) and Contra Costa Transportation Authority (CCTA) are seeking input on the environmental scope of the project and project alternatives.

The proposed State Route 239 Project would provide a new, four-lane highway from State Route 4 at Marsh Creek Road in Contra Costa County to Interstate 580 in Alameda County or Interstate 205 in San Joaquin County. This new state route would ultimately improve the transportation network for an area that has few viable north-south roadway connections in this approximately 17-mile stretch between eastern Contra Costa and the Central Valley.

A joint Draft Environmental Impact Report/Environmental Impact Statement (EIR/EIS) is anticipated to be circulated for public review and comment in 2023. The purpose of environmental scoping is to identify the environmental topics that the project team should study to assess the potential environmental impacts of a construction project. Public input on this project is critical for ensuring the SR 239 project team’s studies are comprehensive and thorough. On this website you will be able to review informational materials and submit comments to inform this phase of the project.

Notice of Intent

On November 18, 2022 a Notice of Intent to prepare a Draft Environmental Impact Statement was submitted in accordance with the National Environmental Policy Act (NEPA). This Notice of Intent starts the environmental scoping process under NEPA. During this period, the public and other stakeholders are invited to provide input on the range of issues and potential alternatives to be addressed in the EIS.

We welcome you to submit comments during the 62-day comment period from November 18, 2022 to January 18, 2023, and to join us at a virtual public scoping meeting on December 13, 2022. Instructions for joining the public meeting will be posted on this website on the day of the meeting.

Notice of Preparation

Previously, in December 2021, a Notice of Preparation (NOP) was issued for the Environmental Impact Report (EIR) in accordance with the California Environmental Quality Act (CEQA). A virtual public scoping meeting was held on January 20, 2022. Below you can view the NOP and the presentation given at the NOP scoping meeting.
