Temporary Road Closure – 10th Street at Old Highway 

July 22, 2026 – Mariposa County Sheriff's Office officials announce temporary road closure on 10th Street at Old Highway in Mariposa. Beginning Thursday, July 23, 2026, 10th Street at Old Highway will be closed until further notice.

Why is 10th Street temporarily closed?

This temporary closure is being put in place to improve safety around the Sheriff’s Office. We’ve received multiple reports of vehicles traveling at excessive speeds in this area, creating a dangerous situation for staff and pedestrians. There have been several close calls, and this closure is intended to help prevent someone from being seriously injured.

The closure is authorized under California Streets & Highways Code 942.5 and is being implemented to protect the public.

Homes located on 10th street can be accessed by using Jones Street.

We’ve received a lot of questions about the temporary closure of 10th Street, and we want to explain why this decision was made.

The Sheriff’s Office has facilities on both sides of 10th Street, which means our staff, deputies, community members, and visitors are constantly crossing back and forth throughout the day. We also serve as the location for child custody exchanges, bringing families and children to this area on a regular basis.

Unfortunately, we’ve experienced multiple close calls over the years. Vehicles often travel through this area at unsafe speeds, and we’ve even had patrol vehicles struck by passing traffic. The intersection of 10th Street and Old Highway has no stop sign, the roadway is narrow, and the steep hill creates limited visibility for both drivers and pedestrians. Those factors combined create a dangerous situation.

Our goal is simple: to get ahead of a tragedy before one happens.

This temporary closure is not intended to be a permanent solution. We recognize that a long-term answer will require additional planning and collaboration. However, doing nothing while we wait for a permanent fix is not an option.

The safety of our employees, community members, children participating in custody exchanges, jurors, witnesses, victims, and everyone who visits our facilities must come first.

We appreciate your patience and understanding as we work toward a safer solution for everyone. Using another alternate route may add a few extra seconds to your drive, but if it helps prevent even one crash, those few seconds are well worth it.

Thank you for your patience and understanding as we work to make this area safer for everyone.
