Lane closure

Interstate 12’s new westbound lanes between 4-H Club Road and O’Neal Lane are scheduled to open Tuesday, but motorists face the closure for months of two of the three westbound entrance lanes at South Range Avenue.

Two of the entrance lanes carrying traffic toward Baton Rouge from Range will be closed about 1,000 feet past the ramp meters, officials said

The plan calls for shutting down all three westbound entrance lanes to I-12 at South Range Avenue on Wednesday evening, said Bill Grass, a spokesman for the Geaux Wider Program.

When the westbound South Range Avenue ramp reopens around 5 a.m. Thursday, only one of the three lanes will be operational 1,000 feet past the ramp meters, he said.

The lanes likely will remain closed until near the end of the year, he said.
