The SR 400 Express Lanes is one of the 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.
Interactive Access Point Map
A constructability study was done by our consultant partners in early 2019 and we found that with the addition of bus rapid transit (BRT), opening to traffic on the original timeline (2024) wasn’t feasible. We adjusted the schedule in June 2019 to reflect an open to traffic date of 2026. With this update, project letting shifted a couple of months; however, we are still on track to meet our INFRA grant obligation deadlines.
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.
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, 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
The next opportunity to provide official comment and feedback about the project will be in mid-2020 at a series of Public Hearing Open Houses (PHOHs).
Georgia Express Lanes
The Georgia Express Lanes are a network of optional, priced managed lanes that run alongside existing interstates in some of the most congested corridors around metro Atlanta. These lanes provide motorists and transit customers with a choice for more reliable trip times during peak travel periods. The result is a network of lanes that provide more reliable and predictable travel times. All Georgia Express Lanes rely on variable pricing, with toll rates rising as demand increases during peak periods of travel and falling at off-peak times. Read more here.
Noise barriers will be evaluated as part of this project in accordance with the Georgia DOT noise policy and Federal Highway Administration noise regulations. Property owners and renters who would benefit from a proposed noise barrier will be given the opportunity to participate in noise barrier voting. Download a noise barrier fact sheet here.
