This $19.7-million Caltrans project creates a new concrete barrier within the median and a resurfaced freeway on one of the most traveled and worst areas of freeway in California. It is located on Highway 80 in Solano and Napa counties in and near Vallejo, from east of the Tennessee Street overcrossing to American Canyon.
The scope of work involved a median freeway widening and repave with asphalt. The project team also replaced the existing thrie-beam guardrail with a new concrete median barrier, installed all new median drainage, built three retaining walls totaling approximately 2,200 lineal ft, and grinded and rehabilitated the existing roadway and overlay with 22,000 tons of open graded asphalt, 40,000 tons of asphalt and 35,000 tons of rubberized asphalt.
