[ARCHIVED] Rush Hour Traffic Improving through N.C. 55 Construction

Last week was a difficult one for anyone traveling N.C. 55 at rush hour. But traffic through two newly-configured intersections is moving more smoothly this week and should continue to improve in the weeks ahead.

Work isn’t finished yet on signalized U-turn lanes (known as superstreets) designed to keep traffic flowing on N.C. 55 after the Target-anchored Holly Springs Towne Center opens to shoppers next month at New Hill Road.

But the opening of more U-turn lanes and timing adjustments to traffic signals already are helping at the New Hill Road / West Holly Springs Road and Green Oaks Parkway / Ballentine Street intersections. More changes are coming soon, including synchronizing of all of the traffic lights and installation of traffic sensors in pavement.

The shopping center developer is installing the U-turn lanes as a requirement to handle increased traffic expected from the center.

The N.C. Department of Transportation says the redesign is meant to help move more highway traffic faster by replacing left turns and through movements from side streets.

State transportation engineers stress that the new configuration cannot function at its best until all lanes are open and signals can detect traffic conditions and adjust accordingly.

The N.C.D.O.T. offers these tips for commuting safely and quickly until the work is finished.

Before the end of February if weather permits, the shopping center developer hopes to be finished with the new traffic pattern, sometimes referred to as a superstreet.

Once the work is finished, motorists on N.C. 55 can resume left turns onto the side streets. State transportation engineers say that will reduce the number of vehicles in U-turn lanes.

However, drivers on New Hill Road, West Holly Springs Road, Green Oaks Parkway and Ballentine Street will continue turning right. They will use the U-turn lanes to get to the other side of the highway or to head in the other direction.

Both the Town and N.C.D.O.T are working with the developer to speed road work along. The first week of superstreets along N.C. 55 was especially challenging, Sudano said.

Feedback from motorists through a Town e-mail account,, has helped traffic engineers pinpoint ways to improve traffic flow, said Town Engineering Director Stephanie Sudano. Town officials have shared that feedback immediately with state transportation officials. This has resulted in changes to signal timing and other project components to assist during the construction period.

"The feedback we receive is very valuable information," Sudano said.

The so-called “superstreet” design for N.C. 55 dates to at least 2008, when plans for the shopping center were approved.

Use of the relatively new superstreet design is growing in the Triangle and elsewhere as a way to keep traffic flowing on major roads where congestion is increasing substantially.

In addition to Target, the first phase of Holly Springs Towne Center will include Marshalls, Petco, Michaels, Pier 1 Imports, Ulta, Dick’s Sporting Goods, Children’s Place, Kay Jewelers, Charming Charlie, Massage Envy, and Mattress Firm.

Restaurants and other food establishments will include Olive Garden Restaurant, Buffalo Wild Wings, Orange Leaf Frozen Yogurt, Which Wich Superior Sandwiches, Zaxby’s, and Starbucks. A movie theater and bowling alley are in phase II.
