ROAD WIDENING AND RECONSTRUCTION WORK IS UNDERWAY: Construction of this roadway widening project is now underway. For your convenience, a special website and social media pages have been created to help keep you informed about this project.


During construction there will be traffic control and detours. At times access to sidewalks and street parking may be restricted or closed. Night work may be necessitated in order to lessen impacts during peak commute hours.

Traffic Delays Expected on Stony Point Road September 11-29, 2017: The next phase in the paving operation along the Stony Point Road corridor is moving to the west side of the roadway from Mesa Way to Pearblossom Drive. This phase will begin Monday, September 11 and continue through September 29. Construction crews will be grading and paving the roadway and traffic will be heavily impacted.

Stony Point Road will remain open at all times, with flaggers in place to assist traffic at inter-sections as needed. All schools and businesses in the area will be OPEN during construction. Take alternate routes if possible.
