MTA plans for the next 40 years include historic streetcars

The MTA is unveiling its full proposal for what transit lines could be built -- and when -- if Los Angeles County voters approve a half-cent sales tax increase in November.

Metro has released its plan to transform transportation in Los Angeles County.

The plan includes spending $120 billion in tax revenue over 40 years. Voters must approve the tax increase proposal on the November ballot.

The ballot measure would extend an existing half-cent sales tax for two more decades, and raise the county’s sales tax rate by an additional half-cent for four decades or longer. The measure, which needs a two-thirds majority to pass, would boost Los Angeles County’s base sales tax rate to 9.5%.
