The Calamba–Los Baños Expressway[1] is a proposed expressway in the Philippines that will start at South Luzon Expressway Extension (Calamba Exit) traverses along Laguna de Bay and ends up connecting a national road at Bay, Laguna. The construction of the four-lane 15.5adj=midNaNadj=mid expressway will cost an estimated PHP5.9 billion or US$131.11 million.[2] When constructed, it is expected to ease the traffic in the Calamba-Los Baños area, particularly along Calamba–Pagsanjan Road.
