The SR 400 Express Lanes is one of the initial 11 Major Mobility Investment Program projects to improve mobility along this vital north-south transportation corridor. The project will be part of the larger Georgia Express Lanes network, designed to provide a connected transportation system with reliable trip times for motorists.
The project focuses on adding two buffer-separated express lanes in each direction between the North Springs MARTA Station and McGinnis Ferry Road. Additionally, one buffer-separated express lane will be constructed in each direction from McGinnis Ferry Road to McFarland Parkway.
The project is in early stages of development, so the initial concept design is underway and access points are still being determined. Based on comments received at the Public Information Open Houses (PIOHs) in February and March of 2019, along with feedback from the City of Sandy Springs, the project team has evaluated the proposed design of the express lanes at the Northridge area. An alternative has been proposed and while it is not the final design, we are pleased to demonstrate that the Department is serious about listening and responding to concerns from the communities we serve. The alternative that is being considered moving forward can be found here.

Project Public Participation
Public Information Open Houses
A series of Public Information Open Houses (PIOHs) were held in February and March of 2019. The purpose of the meetings was to provide opportunities for the public to view current plans, ask questions, and provide feedback. More than 1,200 people attended the series and submitted over 550 comments.
September 3, 2019: Tim Matthews, the MMIP Program Manager, presented a project update to the Sandy Springs City Council. Based on feedback received at the PIOHs earlier in 2019 as well as letters received from Mayor Rusty Paul, an alternative design is being considered near Northridge Parkway.
