HOUSTON, Aug 1 (Reuters) - Williams Cos ( WMB ) got the

green light to continue building its Louisiana Energy Gateway

project (LEG) on Wednesday, a natural gas pipeline, after a

court threw out rival company, Energy Transfer's ( ET ) last bid

to halt its construction.

The two companies have been in dispute over Williams' LEG

project, under construction in Texas and Louisiana, after Energy

Transfer ( ET ) pushed back on the line for crossing its own systems.

Williams crossed the final hurdle on Wednesday, after a

favorable ruling from the 30th Judicial Court of Vernon Parish,

Louisiana brought an end to the crossing disputes.

"Construction can begin in earnest on the Louisiana Energy

Gateway, which is expected to be in service by the second half

of 2025," a Williams spokesperson said on Thursday.

The 1.8 billion-cubic-feet-per-day (bcfd) line would feed

gas from the Haynesville shale field to the U.S. Gulf coast.
