What is Measure R?

Measure R is a half-cent sales tax for Los Angeles County to finance new transportation projects and programs, and accelerate those already in the pipeline. The tax took effect July 2009. Measure R alone does not fully fund all projects. The Measure contains an Expenditure Plan that identifies the projects to be funded and additional fund sources that will be used to complete the projects.

The Measure R Expenditure Plan

The Measure R Expenditure Plan devotes its funds to seven transportation categories as follows: 35% to new rail and bus rapid transit projects, 3% to Metrolink projects, 2% to Metro Rail system improvement projects, 20% to carpool lanes, highways and other highway related improvements, 5% to rail operations, 20% to bus operations, and 15% for local city sponsored improvements.

Taxpayer Oversight

All Measure R funds will be spent in accordance with the plan approved by voters. There will be an annual independent audit and report to taxpayers and ongoing monitoring and review of spending by an independent taxpayer oversight committee.


Prior to any approval and commencement of any Measure R project, any necessary environmental review required by the California Environmental Quality Act (CEQA) shall be completed.
