Northwest Corridor Express Lanes Named No. 1 Project by Roads & Bridges

Staff Report From Metro Atlanta CEO

Tuesday, October 16th, 2018

The Georgia Department of Transportation’s Northwest Corridor Express Lanes Project has been recognized as the No. 1 project on the 2018 Roads & Bridges Top 10 Roads list. This infrastructure project, the largest of its kind in state history and most innovative express lanes project in the country, opened Sept. 8. with the goal of alleviating congestion and providing more reliable travel times for commuters. 

Roads & Bridges' Top 10 Roads awards, created in 2000, recognize the top projects in North America. Each year, nominations are submitted to the R&B editorial staff, which determines the Top 10 list based on project challenges, impact to region, and scope of work.

The Northwest Corridor Express Lanes Project included the design of six new express lane interchanges on I-75, new access points, and 39 bridges with lengths totaling about 27,500 linear feet. The project did not use existing general purpose lanes interchanges and as a result, four separate access points, some created using isolated side roads, were constructed for the I-285 interchange alone. This, combined with successfully navigating a tight working space and managing environmental sensitivity, are some of the key factors which led it to be named the No. 1 project for 2018.

The project improves travel in the I-75/I-575 corridor by adding nearly 30 miles of express lanes along I-75 from Akers Mill Rd to Hickory Grove Road and along I-575 from I-75 to Sixes Road. Two express lanes were built to the west of the existing lanes along I-75 between I-285 and I-575. From that interchange, one express lane has been added along I-75 north to Hickory Grove Road and one express lane has been added along I-575 to Sixes Road.

“Georgia DOT is honored to receive this award from such a fine publication that is highly valued in our industry,” Georgia DOT Commissioner Russell R. McMurry, P.E. said. “The Northwest Corridor Express Lanes Project was a major undertaking that spanned several years and involved the support of the state legislature, local organizations and stakeholders, and Georgia citizens. 

“The Northwest Corridor Express Lanes offer a glimpse into the future of Georgia’s transportation network, which includes a connected system of express lanes in metropolitan Atlanta. We view this project as one of the most transformative projects in state history, enhancing both mobility and transportation choice for Georgia motorists. It is also a leading example of public-private partnership at work to accelerate construction and reduce impacts. Thanks to the support of Governor Deal and the Georgia General Assembly, we are able to continue this innovative work for years to come using the Northwest Corridor model.”
