TDOT gave Channel 3 a tour inside the construction zone Tuesday where they are getting ready for Phase 1 of the project to begin. 

The work is being done at the Interstate 24-75 split in an effort to cut down on traffic and the number of accidents. TDOT says they plan to widen I-75 to include an additional lane in each direction.

TDOT officials said interstate congestion is an issue near the split and this project aims to fix it.  

"The main issue is to make I-75 a true mainline where anything exiting or merging into I-75 occurs on the right side of the road," said project manager Mike Nadolski. 

TDOT tells Channel 3 the modified split will also improve driver safety-- one of their top priorities. 

"Safety and weaving are amongst the highest-- it's not just about capacity," said Nadolski. 

The project is split up into two phases. 

Crews are currently stockpiling dirt so they will be ready to begin construction for Phase 1 later this fall. 

TDOT says Phase 1 will cost approximately $130 million and will wrap up in June 2021.

They plan on starting the second and final phase shortly after. 

TDOT says the project will take several years to complete and will cost around $200 million total. 

Officials say there will be road closures and detours. They will notify the public days in advance so drivers can plan an alternate route.
