The passage of Measure M at the ballot box this week will herald sweeping changes for Los Angeles’ transportation system.

“Today we can stand here and say LA is leading the nation,” said Mayor Eric Garcetti at a press conference Wednesday, noting that Measure M’s $120 billion in funding represented more than 50 percent of the infrastructure investments approved by voters across the country on Tuesday.

While the half-cent sales tax increase doesn’t go into effect until next year, transit leaders are already promoting the projects that will transform the region. Which will affect your commute first?

Overseeing Measure M’s progress will be Metro CEO Phil Washington, who manages a list of projects to be prioritized. Dubbed “Operation Shovel Ready,” these are projects that have not only been approved, but also have additional momentum due to outside funding, public-private partnerships, or strong support in the local community.

Here’s how Measure M will work. Once the half-cent sales tax increase kicks in July 1, 2017, revenue will start flowing to all 88 cities in Los Angeles County for local projects such as sidewalk improvements and pothole repairs. Decisions about how to spend the money will be left to those cities. Depending on where you live, you may see new bike lanes, better curb cuts, or smoother roads in the second half of 2017.

Funds will also start to funnel toward the bigger infrastructural projects on the Operation Shovel Ready list. Some of the better-known transit projects that will be accelerated by Measure M—a rail line to LAX, a subway under the Sepulveda Pass, and a Purple Line extension to Westwood—were actually already given a boost by Measure R, the half-cent sales tax increase passed in 2008, which doesn’t expire until 2039.

There are also plenty of highway, bridge, and high-occupancy lane projects on the freeway shovel-ready list, which you can see on the 40-year plan released by Metro to frame Measure M’s improvements, and a list of which projects will be accelerated by M.

Here are the transit projects that will be prioritized under Measure M:

Airport Metro Connector at 96th Street : Station design and construction for transforming a stop of the Crenshaw Line into an airport gateway that connects with a people mover to the terminals.

Metro Gold Line Eastside Transit Corridor : Technical study to extend the Gold Line eastward to Whittier or travel along State Route 60 to South El Monte (these are two options currently being debated).

Crenshaw Line Northern Extension : A feasibility study would look at connecting the under-construction Crenshaw Line from the Expo Line to the Purple Line at La Cienega and also potentially the Red Line in Hollywood.

: Grade separation and other upgrades for the Valley’s transit line. Rail to Rail/Rail to River Trails : This is probably the most exciting new idea for LA: An engineering study for “active transportation” biking and walking corridors that would connect rail stations to rivers and other recreational areas.

: This is probably the most exciting new idea for LA: An engineering study for “active transportation” biking and walking corridors that would connect rail stations to rivers and other recreational areas. San Gabriel Valley Greenway : A study for 135 miles of protected bikeways and pedestrian trails along rivers and streams in the San Gabriel Valley.

: A study for 135 miles of protected bikeways and pedestrian trails along rivers and streams in the San Gabriel Valley. LA River Bike Path: A study and conceptual designs to address the eight-mile gap in the bike path between Riverside Drive near Elysian Park and the city of Maywood.

Calling all of these projects “shovel ready” is a bit of a misnomer as some of the things that are “ready” are environmental reports and feasibility studies. But since these types of reports and studies can sometimes take years, it is almost guaranteed that Measure M money would speed up the process and move more quickly to the construction stage.

One thing is for certain—no other city in the country will be able to build transit infrastructure as quickly as Los Angeles, at least for the next few decades. “This is the boldest, most comprehensive transportation initiative in North America,” said Washington at the conference yesterday. “We are ready to build. We are ready to build right now.”
