Fresno County begins paving three miles of Mount Whitney Avenue near Riverdale
Crews were paving about three miles of Mount Whitney Avenue near Riverdale, a $5.8 million to $6.4 million job that could shape farm, school and emergency access.
Fresnno County’s work on Mount Whitney Avenue was more than a fresh layer of asphalt: it was a test of how quickly rural roads east of Riverdale can be brought up to standard when farm traffic, school buses and emergency vehicles depend on them. Crews were paving about three miles of the corridor between Blythe Avenue and Garfield Avenue as part of the county’s 2026-27 road overlay program, while county bid documents placed the formal reconstruction project between S. Marks Avenue and S. Blythe Avenue in the unincorporated community of Riverdale.
The project is officially titled Mt. Whitney Avenue Road Reconstruction and Shoulder Improvements, and its scope went well beyond resurfacing. County documents called for reconstruction of the travel lanes, an eight-foot paved shoulder and the parking area using a full-depth reclamation cement treated method, along with signage and striping, excavation and construction of a retention basin, storm drain improvements, and adjustments to sewer manholes and water valve boxes. The engineer’s estimate ranged from $5.8 million to $6.4 million, and the base work was set at 90 working days.
An addendum also opened the door to a pedestrian safety upgrade at Mt. Whitney Avenue and Feland Avenue. The optional bid item would install a Pedestrian Hybrid Beacon, also known as a HAWK system, and would add 20 working days if awarded. That detail matters in Riverdale, where roads do not serve only commuters. They carry tractors, harvest trucks, workers headed to fields, children riding school buses and ambulances trying to reach people quickly across long rural stretches.
The Mount Whitney work sits inside a larger county system that stretches across more than 3,400 miles of paved and unpaved roads. Fresno County’s Road Maintenance and Operations Division says its job is to maintain and improve that network so residents can travel safely and efficiently, and the department says its broader mission is to improve the economic, environmental and social quality of life for people in Fresno County. County current projects also include a separate Mount Whitney Ave Complete Streets Project, signaling that this corridor is still moving through a broader planning pipeline.
Funding came from the Surface Transportation Block Grant Program and a Fiscal Year 2022 Congressionally Directed Spending appropriation, underscoring that local roadwork in Riverdale depended on outside transportation dollars as well as county priorities. The deeper question is where this segment fits in the county’s queue: which rural roads get fixed first, which ones remain deferred, and whether communities on the agricultural edge of Fresno County are seeing investment that matches the demands they place on the system every day.
