The “diverging diamond” design has cars crossing over to the opposite side of the Catawba Avenue bridge to make entering and exiting the highway flow more smoothly.
The DOT Is planning to rebuild the I-77 overpass into what’s called a “diverging diamond interchange,” or DDI. Under the new design, the eastbound and westbound lanes of Catawba Avenue actually will cross over one another in a new traffic pattern that’s supposed to improve traffic flow and make entering and exiting the highway smoother.
The Town of Cornelius is planning a simultaneous project to improve the appearance of the overpass, making it a “gateway” to town. Plans call for a nautical-themed design with decorative bridge abutments, 5-foot lanterns at four corners, a central pedestrian walkway on the bridge, and trees and other plantings.

The N.C. Department of Transportation has given Cornelius officials an updated timeline for the planned Exit 28 reconstruction project, and it offers some hope for drivers and businesses on Catawba Avenue: It may not take as long as originally projected. Cornelius officials now say they expect the work will last 14 to 18 months, from the start of utility relocation this fall to the end of construction. They previously had warned the project could take two years.
Town officials and a spokeswoman for the NC DOT both said Wednesday the situation remains confusing and complex, and the timeline is just an estimate. But if all goes smoothly and weather and other delays are limited, the project could be completed in early to mid-2015.
The DOT hopes to choose a wining bidder in late September, and the project could begin as early as Oct. 28, according to DOT spokeswoman Jennifer Thompson. Read the full story
