In a report published on Monday, December 18, the Tennessee Department of Transportation (TDOT) revealed that the widening of State Route 6 has made it into the statewide 10-Year Project Plan.

State Route 6, better known as Highway 31 or Main Street to Spring Hill residents, has been a candidate for widening in the past. In 2019, TDOT did commit funding to the project as part of its three-year plan; however, that funding was removed.

Now, the project is planned to begin taking shape toward the end of this decade.

According to the 10-Year Project Plan, Highway 31's widening will be divided across two concurrent projects. 

For the southern portion, preliminary engineering is set to start in 2028, while right-of-way acquisition will begin in 2030.

For the northern portion, preliminary engineering is set to start in 2030, while right-of-way acquisition will begin in 2032.

Construction is planned for 2033.

"This commitment by TDOT is a major win for the residents of Spring Hill and wouldn't have become reality without the dedicated work of the BOMA and City employees," said Spring Hill Mayor Jim Hagaman. "The widening of Highway 31 has been a priority for our City for years, and we are delighted to finally have this project scheduled and funded."

The total price tag comes in at an estimated $299.8 million.

As mentioned in the 10-Year Project Plan, TDOT will be working with local communities to further describe the needs of the projects featured. As more information about this project becomes available, the City of Spring Hill will provide updates.
