[ARCHIVED] Roundabout Project Underway at First and California


The City of Napa’s Roundabouts Project is underway. The project to construct the State Route 29 (SR 29) Northbound First Street Ramps and California Boulevard Roundabouts began back in July 2018. The following summarizes project progress so far and what is to come.

Utility relocation (AT&T, Comcast and PG&E) is necessary to clear the necessary space to begin the demolition and grading of the new intersection.  

Similar to the utilities, there are some trees that need to be removed to accommodate the footprint of the project. A tree contractor, The Professional Tree Care Company, will take out only those trees that need to be removed in the coming months. There will be occasional traffic control through the intersections during this phase.    

Demolition, grading for the project and construction of the roundabouts will begin in earnest during Spring 2019 and is anticipated to be complete by Winter 2020. 

The final phase of the project will be to install project landscaping, which includes the planting of trees and ornamental plants designed to create an enhanced east-west corridor through Napa as well as replace plantings and trees removed as part of the project.


  • AT&T and Comcast have mobilized and relocated their facilities. 

In Progress:

  • PG&E Gas and Electric mobilizing in Sept/Oct 2018 to relocate their underground facilities.
  • Tree Removal will be occurring between now and the end of November 2018.

Coming Up:

  • Staged demolition and grading to begin in April 2019.
