Santa Rosa - As part of the Highway 101/Hearn Avenue Overcrossing Replacement Project in Santa Rosa, Caltrans will close Highway 101 near Hearn Avenue in Santa Rosa, a closure that will allow workers to demolish the old Hearn Avenue overcrossing, after traffic is moved onto the partially-built new overcrossing this weekend.

To prevent traffic from driving below the old Hearn Avenue Overcrossing while it’s being demolished, Caltrans will detour northbound Highway 101 traffic at the Yolanda Avenue exit and southbound Highway 101 traffic at the Baker Avenue/Corby Avenue exit.

Closure Hours

  • Friday, June 20, 8:00 p.m. – Saturday, June 21, 800 a.m.
  • Saturday, June 21, 9:00 PM to 9:00 AM Sunday, June 22.

Additionally, the northbound Highway 101 on-ramp from Yolanda Avenue and the southbound Highway 101 on-ramp from Baker Avenue will be closed during the mainline freeway closure.

Detours

Caltrans and its partners, the Sonoma County Transportation and Climate Authorities and the City of Santa Rosa, broke ground on the Hearn Avenue Overcrossing Replacement Project in March 2024.

During the project, the existing overcrossing, which has one lane in each direction and a single sidewalk, will be replaced with a new overpass with two traffic lanes per direction, one bicycle lane per direction, and a sidewalk on each side.
