The Los Angeles Metropolitan Transportation Authority Board approved a transportation expenditure plan Wednesday that would place a countywide half-cent sales tax increase on the upcoming November ballot.

The sales tax measure would fund $140 billion for use in a variety of transit and highway projects, roadway improvements, and pedestrian and bike paths.

The Los Angeles County Traffic Improvement Plan, approved by the Metro board in an 11-2 vote, aims to create a source of sustainable funding for new rail and bus lines, including a subway line from the San Fernando Valley to the Los Angeles International Airport.

“Today’s action paves the way towards building and sustaining a world-class 21st century transportation system here in Los Angeles County to accommodate the region’s growing needs,” said Mark Ridley-Thomas, chair of the Metro board, in a statement Wednesday.

The measure is expected to be voted on by the Los Angeles Board of Supervisors in August. It would then be placed on the November ballot if approved. Metro is also looking to extend the existing half-cent Measure R sales tax by 18 years, meaning it would run through 2057.

“Our region is on the move and it’s time we stop letting traffic hold us back,” said Los Angeles Mayor Eric Garcetti. “This bold transportation plan will relieve our congested roads, connecting our region with the robust, comprehensive transportation system we need and deserve.”

Also on the agenda, the Metro board approved a staff request to add $10.9 million to its fiscal year 2017 budget in order to fund election-related and public information activities.
