The U.S. Army Corps of Engineers' announcement Sunday that work would be halted on the Dakota Access pipeline was met with jubilation by protesters and their many celebrity supporters online.

On Sunday, the Corps denied an easement for the pipeline to cross Lake Oahe, a reservoir on the Missouri River in North Dakota and a major water source for the Standing Rock Sioux reservation. That segment was the only contested part of the 1,172-mile pipeline, which is almost completed.

Celebrities like Shailene Woodley have been outspoken against the project, which protesters said would contaminate drinking water and disturb sacred sites. Woodley was arrested while participating in the protests in October.

The actress and a host of other celebs took to social media after the news broke Sunday night to express their joy and celebration.

"Solid proof that people coming together can change things for the better," said Pharrell Williams.

"Bravo Army Corps of Engineers, bravo Standing Rock, bravo Sioux Nation. You've taught us all something of great value. Stand your ground!" added Sally Field.

Despite this victory for the anti-DAPL protestors, the project, which is 92% complete, will undergo further study for potential alternative routes at the order of the Army Corps of Engineers. That decision could be reversed by President-elect Donald Trump when he takes office in January. There are also two pending court cases in North Dakota and Iowa regarding the project.
