Diverging Diamond Interchange

CMES Inc. crews are scheduled to complete the Georgia Department of Transportation's (GDOT) $26.4 million project in Bethlehem to construct a full diamond urban interchange providing access to and from SR 316 to the crossroad SR 81, on Oct. 31,. The project, taking place in Barrow County, is being financed by state funds.

A project first proposed in 2015 is going to construction after the Georgia Department of Transportation (GDOT) awarded a contract July 31 for the installation of a diverging diamond interchange (DDI) at I-75 and State Route 20 in the Henry County town of McDonough.

Construction of the SR 120/Union Road Interchange takes place in the city of Manteca, which is is the first ever Diverging Diamond Interchange (DDI) in California.

As part of the California Department of Transportation (Caltrans) and San Diego Association of Governments (SANDAG) state Route 11 (SR-11)/Otay Mesa East Port of Entry project, crews from Skanska US Civil are constructing the final segment of the future toll road SR-11 and the southbound connector ramps, linking southbound State Route 125 (SR-125) to eastbound SR-11 and eastbound state Route 905 (SR-905).

Officials ceremonially shoveled dirt in Austin last July to launch the latest rendition of an interchange design called a "diverging diamond interchange." Commonly referred to as a DDI, the design is a relatively new wrinkle in highway architecture. It continues to find favor in the United States for the simple reason that it moves traffic safely.

DDIs are particularly effective at locations, like the one in Alabama, that have: High volumes of left-turn traffic on and off of freeway ramps Left-turn related safety challenges  Moderate and unbalanced crossroad traffic through the interchange A need for additional capacity, without widening  According to the Alabama Department of Transportation (ALDOT), "DDIs improve safety by reducing vehicle-to-vehicle conflict points from 26 — as in a conventional diamond interchange — to 14 points.

Phase 2 of the Florida Department of Transportation's (FDOT) First Coast Expressway project (FCE) is underway and expected to be delivered in mid-2025. Back in March, crews from Sacyr Construction USA LLC first began working on the north segment of the job, a $229 million contract that is being funded by the Florida Turnpike Enterprise.

Another diverging diamond intersection (DDI) is coming to Travis County, following a groundbreaking ceremony on July 24 for the I-35 at Parmer Lane project. The Texas Department of Transportation was joined by Texas Transportation Commission Chairman J.

Described as a project that will help move people and products for decades to come, a $50 million undertaking to reconstruct two busy interchanges along Interstate 17 in north Phoenix, Ariz., is under way. The Arizona Department of Transportation (ADOT) is overseeing the work, which started in late November 2018.

Work is set to begin in March on Segment 2 of the $1.6 billion I-75 modernization project in Oakland County, Mich., part of the Detroit metropolitan area. The roadway is the most heavily used commuter route in the county, with 174,000 vehicles traveling it daily.

Considered one of the top ten construction priorities for the Utah Department of Transportation (UDOT) in 2018, the I-215 Redwood Road project requires crews to build a new bridge east of the existing Redwood Road bridge over I-215. The ongoing work also includes converting the existing I-215 and Redwood Road interchange to a diverging diamond interchange.
