BATON ROUGE — Shreveport's Interstate 49 inner city connector project is teed up for a $100 million cash infusion in a surprise bill that secured final passage here Tuesday.

"It's huge for us," said Sen. Barrow Peacock, R-Bossier City.

House Bill 578 by Rep. Tanner Magee, R-Houma, had initially included $275 million for two road projects, but it expanded to $690 million for 10 key infrastructure projects throughout the state as it moved through the Legislature.

"This is the bill of the session," said Sen. Page Cortez, R-Lafayette, chairman of the Senate Transportation Committee. "It's like opening packages at Christmas."

Lawmakers are financing the projects with $700 million the state secured in the settlement for the 2010 Deepwater Horizon Gulf oil spill.

Though the state receives the money in annual payments of $53 million, the projects could be bonded out to begin work almost immediately.

The bill now heads to Gov. John Bel Edwards' desk for his signature.

Peacock and fellow Shreveport-Bossier City-area Sens. Ryan Gatti, Republican, John Milkovich, Democrat, and Greg Tarver, Democrat, signed off on the amendment that added Shreveport's project to the bill.

"It's a clear catalyst for economic growth and prosperity," Peacock said.

State Rep. Larry Bagley, R-Stonewall, was the catalyst for the project to be amended into the bill.

"It will change the face of Shreveport and give the city a kick start to add business and industry by making the city more accessible," Bagley said. "The project will benefit every person in and around Shreveport."

The state funding makes the project eligible for multiples of matching federal funds for the $547 million project.

"Now it's up to the congressional delegation to step up to the plate and secure federal funding," Peacock said.

The state has a $14 billion backlog in infrastructure maintenance.

"This is going to biggest infrastructure investment in three decades and shows we can make a meaningful impact when we work together," Magee said.

The following projects are the 10 projects in the bill:

Capital region: Hooper Road widening from Louisiana 3034 to Louisiana 37 (Baton Rouge), $15 million;

New Orleans: Acquisition of two cranes for the Port of New Orleans, $20 million;

Central Louisiana: Sugar House Road extension (Alexandria/Rapides Parish), $19 million;

Statewide: System bridge program, $40 million;

Southwestern Louisiana: New Cameron Ferry, $20 million;

Shreveport: Interstate 49 inner city connector, $100 million;

Southeastern Louisiana: Louisiana 3241, $50 million;

Acadiana/Lafayette: Interstate 49 South, $150 million;

West Baton Rouge Parish: Louisiana 415, $125 million;

Lafourche: Louisiana 1, $150 million.
