Above is a list of highway and transit projects and programs that would receive funding from the Measure M sales tax ballot measure. The list includes groundbreaking dates and project completion dates. The ballot measure would raise the countywide sales tax by a half cent and continue the Measure R half-cent sales tax beyond its mid-2039 expiration date to fund a number of highway, transit, local street, walking and biking programs.
And below are brief descriptions of the projects. One note: the final version of some of these projects are still to be determined by environmental studies. Many of the highway projects will be done in conjunction with Caltrans, the state agency that oversees highways.
I-5 Truck and Carpool Lane Additions: SR-14 Interchange to Lake Hughes Road. Adds one truck lane and one carpool lane in each direction, while maintaining existing general purpose lanes. Project home page.
