CATEGORY: Innovative Solution/Best New Products PROJECT: SR 11 from CSX RR to CR 681/Stephens Street OWNER: City of Winder, GA DESIGNER: GDOT – Roadway Design The project addressed severe rutting due to an extremely high percentage of truck traffic. The solution consisted of replacing approximately 3/4 mile of pavement with pre-cast concrete panels, the first use of this technology on a roadway in Georgia. Lt. Governor Casey Cagle said at the ribbon cutting ceremony: “This is the way roads should be built,” noting the use of innovative road building techniques and the superb aesthetics of the project. CATEGORY: Environmental Protection, Preservation, Restoration and/or Enhancement PROJECT: Successes of the SR 144 Environmental Assessment OWNER: Bryan County DESIGNER: Adrian Collaborative SR 144 extends through Richmond Hill (site of the historic Henry Ford Plantation and work community) along the Ogeechee River corridor. A 5-mile stretch required improvements to capacity, as well as sidewalk and bicycle access. In addition to preserving historic elements, the project met sustainable goals of improving pedestrian and bicycle access between neighborhoods and adjacent land uses. Many of the adjacent wetlands and essential fish habitat will be preserved, while mitigation for unavoidable impacts will be located in the nearby Ogeechee River basin. CATEGORY: Context Sensitive Design/Public Participation PROJECT: SR 61/113 Widening and Reconstruction at Leake Mounds OWNER: Bartow County DESIGNER: GDOT – Environmental Services Widening this section of SR 61/SR 113 included mitigation of a National Register of Historic Places eligible archaeology site, known as the Leake Site. Located along the Etowah River southwest of Cartersville, GA, this American Indian archaeological site dates back to 300 B.C. Over 50,000 square feet were excavated prior to widening the state highway; project components included developing a 1.5-mile loop trail, with interpretive panels presenting information on the archaeological history and surrounding natural and cultural landscape. This project developed out of a unique partnership between federal, tribal, state and local entities. CATEGORY: Bridge/Structural Design PROJECT: I-85/SR 400 Connector Ramps OWNER: GDOT DESIGNERS: Heath & Lineback Engineers, Inc. The well-known congestion at the GA 400/I-85 interchange was vastly improved by the addition of this project, with further enhancements provided by constructing an adjacent ½ mile pedestrian trail. Significant challenges, including those posed by existing utilities, were addressed by incorporating innovative design elements and strategies that resulted in construction costs coming in almost $10 million below the original estimate. The project is recognized as an outstanding example of superior bridge and structural design that will benefit Atlanta commuters for years to come. CATEGORY: Traffic Safety/Intersection Design PROJECT: Windy Hill Road at I-75 (Diverging Diamond Interchange) OWNER: GDOT DESIGNERS: Cumberland CID & Moreland Altobelli Associates, Inc. The area around the heavily-congested Windy Hill Road and I-75 interchange currently experiences crash rates three times the state average, with injury rates in those crashes double the state average. Traffic volumes are expected to increase 15% in the short term, with the Atlanta Braves’ new stadium and mixed-use development expected to further increase area congestion. Studies show the diverging diamond interchange as successful at reducing crashes and increasing safety. In this location, the design will increase efficient traffic flow without the need to reconstruct the existing bridge over I-75. CATEGORY: Highway Design - Urban PROJECT: Canton Road & GA NE RR Over US 41/Cobb Parkway OWNER: City of Marietta, GA DESIGNER: ARCADIS Dense development in the area led to a high volume of pedestrian and vehicular traffic at this interchange, with a lack of facilities and substandard and/or functionally obsolete bridges causing serious safety concerns. The design solution minimized impacts to adjacent rights of way, reduced maintenance for the roadway and railroad, and improved railroad operations. Effective partnering amongst stakeholders made this project a success, with strong GDOT project management ensuring the project was completed on schedule and under budget. CATEGORY: Highway Design - Rural PROJECT: I-75 at US 41/SR 3 Rocky Face Interchange OWNER: City of Dalton, GA DESIGNER: Kimley-Horn The original interchange configuration created long traffic queues due to a short ramp with insufficient storage and significant accident history. Early in the design process, the I-75 bridge over SR 3 was declared insufficient and its reconstruction was added to the scope. The design team’s Value Engineering Study resulted in relocating a proposed lane into the existing 44-foot median, eliminating stream impacts to 15 identified state waters and wetlands, and reducing linear stream impacts to below permit thresholds. Despite the added scope, the I-bats survey was completed ahead of the USFWS mandate, enabling the project’s completion on schedule. CATEGORY: Design-Build PROJECT: I-75 Aux Lane from Eagles Landing Pkwy to I-675 OWNER: Henry County DESIGNER: Moreland Altobelli Associates, Inc. This project involved constructing an auxiliary lane from Eagles Landing Pkwy./Hudson Bridge Rd. north to I-675. To accommodate tight deadlines, a new lane and allow for potential future adaptations, the design team recommended replacing the existing bridge and relocating it further north to reduce the number of construction stages. This initiated critical phasing strategies, one key aspect of which was a phased Erosion Sediment Pollution Control Plan (ESPCP) and Notice of Intent (NOI) – a first for GDOT and now standard in the delivery of Design-Build projects, allowing schedule savings and earlier Open-to- Traffic dates.
