Nighttime Closures Planned on Herndon Avenue, State Route 99

The California High Speed Rail Authority in cooperation with design build contractor Tutor Perini Zachry Parsons announced a series of nighttime closures along Herndon Avenue and the northbound State Route 99 Herndon Avenue off ramp beginning Nov. 4 and running through Nov. 26, 2025. Work will take place between 9 p.m. and 6 a.m. and will involve intermittent lane closures as crews perform utility and roadway work tied to the broader rail project. The advisory was posted Oct. 31, 2025, and officials say signage and detours will be in place.

Closures will be concentrated on Herndon Avenue between Parkway and Riverside Drive, and will include the northbound State Route 99 off ramp that feeds traffic onto Herndon. Pedestrian access will be restricted in some areas during the overnight operations, though the advisory states that access to businesses and residences will be maintained. Contact information for project representatives is posted on the advisory for residents and business owners who need more information or who may be directly affected.

For Fresno drivers the closures will have practical effects on late night and early morning travel. Motorists using the northbound State Route 99 off ramp to reach destinations along Herndon should expect lane reductions and possible delays during the overnight window. Local traffic patterns may shift as detours redirect vehicles, and businesses that operate late may see changes in customer access. Pedestrians and bicyclists should plan alternate routes where sidewalks are closed, and allow extra time for travel during the work period.

The work is part of ongoing construction related to the California High Speed Rail project. Utility and roadway improvements in this corridor are intended to support the larger infrastructure program, and overnight scheduling aims to reduce disruption to daytime traffic and commerce. Even so, nighttime work can affect neighborhood quality of life because of noise and changed travel patterns, so residents and local leaders will likely want to monitor progress and any unplanned impacts.

The authority and contractor emphasize that signage and detours will be implemented and that direct access to homes and businesses will be preserved. Fresno residents seeking specific schedules or who need to report issues should consult the advisory for project contact information. Local officials and the project team will be responsible for coordinating traffic management and keeping the public informed as work proceeds through Nov. 26, 2025.
