"Thousands of trucks have jammed National Expressway 110 since Aug. 14, creating a traffic jam stretching 100 kilometers. Authorities attribute the mess to highway construction exacerbated by accidents and breakdowns. Police are trying to keep tempers from flaring in what is the second massive jam to tie up the highway in the past month.... No one expects things to improve until the project wraps up on Sept. 13." - Shannon Jiménez
