To improve safety, operation and highway capacity on Interstate 84 in the city of Waterbury, Conn., ARTBA member Lochner was the prime contractor on the 2.7-mile highway reconstruction of a third lane in each direction through the city. Members AECOM and Louis Berger helped complete the $330 million project that included upgrading eight highway bridges and one pedestrian bridge, seven culverts, 20 retaining walls, replacing and upgrading traffic signals, signs and pavement markings, and replacing and relocating utilities. The project also included the relocation of Mad River and Beaver Pond Brook, two bodies of water that run under the highway – a major route for travelers between New York and Boston. It opened in August, a full year ahead of schedule. – Eileen Houlihan

The Snoqualmie Pass is a crucial mountain freight corridor for Washington State. This $564 million project will address projected traffic growth, improv safety, and consider the environmental impact on a 15-mile stretch of Interstate 90. It will provide a six-lane freeway on new pavement designed to last 50 years, help reduce closures due to avalanches and rock slides, and landscaped bridges and culverts for wildlife to pass over or under the highway to protect motorists. Four ARTBA firms are involved in the work: AECOM, design; Jacobs Engineering Group, engineering; and Kuney Construction and Atkinson Construction, contractors. — Mark Holan

The 1970s-era construction of Interstate 71 split Cincinnati’s Uptown neighborhoods but only provided partial access to the highway. This $84 million project—a collaborative effort between the Ohio DOT, City of Cincinnati, and regional governments—reconstructed nearly two miles of the interstate, including new entrance and exit ramps and rehabilitated some older bridges and ramps. ARTBA member Kokosing Construction Company built the full diamond interchange, including several new and rehabilitated bridge structures and 100,000 square feet of retaining walls. The project also widened I-71 and rebuilt numerous local city streets. — John Schneidawind

Georgia Department of Transportation  – Northwest Corridor Express Lanes

Georgia’s Northwest Corridor Express Lanes are a nearly 30-mile connection to downtown Atlanta on Interstates 75 and 575 in densely-populated Cobb and Cherokee counties, which contain several business centers, two shopping malls, and Dobbins Air Force Base. I-75 is one of Atlanta’s most congested commuter and trucking corridors. ARTBA members Archer Western and Hubbard Construction teamed as Northwest Express Roadbuilders for this $840 million public-private partnership (P3), the largest transportation project in Georgia DOT history. Parsons was the lead design engineer and provided integral software to monitor traffic, control messaging signs, and operate access gates. Member firms TranSystems Corp., Arcadis U.S. Inc., and Terracon Consultants, Inc. also contributed. Since opening in September 2018, the express lanes have moved traffic 30 percent faster than general purpose lanes, shaving an hour off rush hour commutes. – Eileen Houlihan

 

Wisconsin Department of TransportationZoo Interchange Core and Adjacent Arterials

The $986 million Zoo Interchange Core and Adjacent Arterial project updated a 1960s freeway. It used a variety of innovative solutions and designs, including efforts to alleviate merging and weaving from the main thoroughfares via 3D modeling. The project included four miles of local roadways, nine miles of freeway, and seven service interchanges. HNTB and Jacobs Engineering Group led the engineering and design team, and four other ARTBA member firms built the project: Lunda Construction Company, Michels Corporation, and Edgerton Contractors, working together as Wisconsin Contractors II in one phase; Walsh Group in a second phase. — Mark Holan
