Major Mobility Investment Program
The Georgia Department of Transportation (Georgia DOT) is committed to improving statewide mobility and building a connected transportation network. An initial 11 Major Mobility Investment Program (MMIP) transportation projects were identified to help move this goal forward.
As the MMIP has developed and design work has progressed, we’ve evaluated how we are delivering the program and refined it to:
- Advance six improvement projects along I-285 already planned as part of the MMIP
- Accelerate the I-85 Widening, Phase 2 project
- Accelerate delivery of the I-75 Commercial Vehicle Lanes project
- Adjust the delivery schedules for the I-285 Eastside Express Lanes, I-285 Westside Express Lanes, and I-285 Top End Express Lanes
These advancements will bring improvements to you sooner and help mitigate disruptive construction congestion. Click here for the updated delivery schedule.
How these advancements benefit you:
- Provide local road improvements earlier in the delivery timeline than previously scheduled
- Provide early operational improvements to I-285 general purpose lanes in advance of major express lanes projects
- Contribute to less disruptive construction congestion and impacts to local roads during major express lanes project construction
- Maintain healthy competition among our bidding developers
- Avoid overwhelming the contracting industry with less projects on the same procurement timeline
The MMIP delivers positive societal benefits at a reasonable cost yielding a benefit of $1.10 for every $1 invested.
- Reduces travel times by 44% for transit vehicles
- Relieves traffic through a travel time savings of 15% or $3.28 billion
- Provides 45 minutes in trip planning time savings
- Curbs pollution with a 13% reduction in vehicle emissions due to less congestion and faster travel times
- Reduces traffic fatalities and serious injuries by 13% due to less congestion and faster travel times
Expanding the Georgia Express Lanes Network
The MMIP includes five express lanes projects, which will expand the Georgia Express Lanes network. Express lanes are travel options for motorists and bus transit customers to bypass congestion for a free-flowing commute. The lanes are a choice that provide more reliable trip times and improve traffic flow.
Proven Success on the Northwest Corridor Express Lanes
- Express Lanes are 30% faster than the general purpose lanes during peak travel times
- Speeds in the general purpose lanes are up to 20 mph faster than before the express lanes opened
- Rush hour has been reduced by over an hour during the morning and evening commutes
- Georgia DOT is responsible for planning, constructing, maintaining, and improving the state’s roads, bridges, and interstates.
- Atlanta-Region Transit Link (ATL) Authority collaborates with regional transit authorities, such as MARTA, CobbLinc, Gwinnett County Transit, and Xpress, that are responsible for operations of heavy, light rail, and bus transit operations and the advancement of transit in the region.
- The State Road and Tollway Authority (SRTA) collects toll revenue and is responsible for operations of the Georgia Express Lanes network.
The major mobility projects will be delivered through innovative methods such as Design-Build and Public-Private Partnerships, allowing Georgia DOT to accelerate construction schedules. The projects will create additional capacity for more reliable trip times, more efficient movement of freight, safety improvements, and expanded multimodal options, including transit.
