Document Description
The California Department of Transportation (Caltrans) proposes to improve operations at four intersections in Merced and Stanislaus counties by replacing existing paved shoulders with widened shoulders to accommodate Surface Transportation Assistance Act of 1982 (STAA) truck turning movements. The four locations are on Interstate 5 (I-5), State Route (SR) 33, SR 140, and SR 165 at the following postmiles: 1) Mer-165-11.73, 2) Sta-5/140-32.39/0.00, 3) Mer-140/33-4.35/26.46, 4) Mer-33/140-27.11/6.04 In addition, it is proposed to remove the existing mainline intersection structural sections at Locations 2 and 4 and replace with Hot Mix Asphalt (HMA) over aggregate base (AB), structural section to vary by location, and to overlay the entire sections in Locations 1 and 3 with 0.2 ft of Gap Graded Rubberized Hot Mix Asphalt (RHMA-G). It is also proposed to install Transportation Management Systems (TMS) elements at all locations, replace one cross-drain at Location 1, and replace or upgrade roadside signs where needed. The purpose of the project is to improve operational efficiency at four intersections on State Highways in Merced and Stanislaus counties by constructing additional pavement at the corners of the intersections to improve Surface Transportation Assistance Act vehicle turning radius, eliminate conflicts with opposing vehicular traffic, reduce traffic congestion and improve traffic flow. Truck turning movements at these intersections do not meet Surface Transportation Assistance Act off-tracking standards, with wheel tracks and swept paths of Surface Transportation Assistance Act trucks encroaching into outside shoulders and opposing lanes.
