Modernize 75 Map

How can I find out about road closures and detours?

Weekly construction alerts will be posted on the website home page. A list of road closures and detours anticipated as part of construction will be posted to, and maintained on the website.

Why was this stretch of I-75 the first segment to start construction?

The first construction segment from north of Coolidge to north of South Boulevard was initially funded several years ago. This 2.69-mile section is the least costly segment of the overall project and does not require property acquisition, which often adds years to a project. Additionally, the Square Lake Road interchange will be modernized with right-hand exits and entrances, which will significantly improve the current outdated design. The improved interchange will be safer and operate more efficiently, with less opportunity for crashes. It will be easier for motorists to enter, drive through, and exit. This segment can be built and can operate independently of the other project improvements.

Who benefits from this project?

Everyone. This portion of I-75 currently carries up to 174,000 vehicles per day, which includes residents, commuters, carpoolers, local businesses, intrastate and interstate commercial vehicles, and tourists. Since this freeway was originally built in the 1960s and has never been rebuilt, modernization is greatly needed. The addition of the HOV lane will help ease the increasing congestion. Improving this aging segment of freeway infrastructure will increase safety and provide an improved driving surface and experience.

Is every effort being made to decrease sound levels?

Yes. Per federal guidelines, all federally funded projects that improve the roadway by adding capacity are required to be studied to determine the reasonableness and feasibility of noise protection. If any area qualifies for noise protection by the FHWA, it will be built as part of the project.

Will any trees be removed during construction? Will there be plantings?

It is expected that some trees will be removed during construction. However, they will be replaced, and in some cases with more trees than what was originally in place. Additional opportunities for landscaping are also included within the project.
