There are several projects underway in Chino. Many of these projects have been in the works for years and once completed, will bring much needed improvements to our community.

We appreciate your patience as you navigate the inconvenience of detours and road closures. Remember to plan ahead and follow posted signage and detours.

Grand Avenue Lane Reductions

Grand Avenue from Pipeline to Roswell Avenue

The next phase of work on Grand Avenue begins January 23 and includes the installation of concrete pavement. Concrete is an alternative to asphalt that is more durable and less likely to create potholes therefore requiring less maintenance and producing a smoother ride.

The work will require several lane closures with portions of the road being reduced to one lane. Access to local businesses will be maintained at all times. Plan ahead, allow for extra travel and use posted detours.

Lane closures will occur on westbound Grand Avenue from Pipeline to Roswell at 9:00am on January 23 through January 29 at 4:00pm.
