We know Austin traffic is a constant source of strife, so what are the plans for some of the city’s biggest thoroughfares?

We looked at the projects already underway for four of Austin’s busiest highways: 183 South, Loop 360, Interstate 35 and MoPac.

To begin, work on 183 South is already underway to create a north-south alternative to Interstate 35.

Crews broke ground on the 183 South project in 2016 and have been working ever since to make it a non-stop, signal-free road.

The project should be finished by 2020 with a total cost of $743 million.

On I-35, there are big plans to add two toll lanes in each direction from Williamson County to Hays County.

Senator Kirk Watson unveiled the $8.1 billion plan for the “Capital Express” project in October. But don’t expect relief on one of the country’s most congested highways anytime soon. This one’s still in the planning stage until at least 2020.

On MoPac, express toll lanes north of downtown are finally open. Now, there are plans to add additional express lanes. The project was stalled in 2016 when Save Our Springs filed a lawsuit over environment concerns. But a judge recently ruled In favor of the project.

The next phase of public input for new MoPac toll lanes won’t start until 2018.

The final major improvement project is set for Loop 360. Like 183 South, the goal is to eliminate stop lights at the four biggest intersections: Spicewood Springs Road, Lakewood Drive, Courtyard Drive and Westlake Drive.

Instead, they’ll build grade separations similar to an overpass, cutting down the time drivers wait, watching red lights turn green.

Construction on Loop 360 won’t start until 2022 and will likely continue through 2024.
