Measure M, Orange County’s half-cent transportation sales tax, continues to make a significant difference in the lives of residents who benefit every day from improvements on freeways, streets and roads, and the transit system.
About Measure M
Voters first approved Measure M in 1990 for a 20-year period. Their trust was rewarded by more than $4 billion in transportation improvements, including adding 192 freeway lane miles, improving 170 intersections and 38 freeway interchanges, and implementing Metrolink service in Orange County. After experiencing 20 years of success and progress, voters renewed the sales tax for transportation improvements in 2006 for another 30 years.
