Buxton

We understand that ocean overwash along N.C. 12 in the Outer Banks often makes it difficult for residents, visitors and businesses to get where they need to go efficiently. The state of emergency declared by Gov. McCrory helps us move forward with a short-term solution to protect this critical coastal highway at its most vulnerable location – the S-Curves.

Overwash at the S-Curves in March 2013

Currently, when overwash occurs at the S-Curves, it often forces N.C. 12 to close, making it challenging for people to get to jobs, education or medical appointments. A series of storms, including hurricanes Irene and Sandy, severely eroded the beach just north of Rodanthe.  Without the beach to act as a buffer, the strong surf threatens to undermine the structure and safety of the road.

That is why we have acquired $20.8 million in Hurricane Sandy emergency repair funds from the Federal Highway Administration to rebuild the beach at the S-Curves. Nourishment will provide much-needed protection to N.C. 12 until we can put a long-term solution in place in the coming years.

Although Buxton also experiences overwash, it was not included in the emergency declaration for several reasons. When overwash occurs, it washes water and sand onto N.C. 12, but it does not currently threaten the road’s integrity. Following recent storms, our crews have cleared the overwash off the road quickly without requiring repairs. In addition, N.C. 12 at Buxton does not qualify for federal emergency repair funds, and is not a candidate for state transportation funding for repair and protection at this time.

We have identified the section of N.C. 12 in Buxton as a “hot spot” that may see increased erosion in the future. We are studying this location to determine feasible long-term options for maintaining transportation along N.C. 12 if future conditions threaten the long-term viability of the existing roadway.

State of Emergency for NC 12 After Storms, High Surf

On March 19, Governor Pat McCrory declared a state of emergency for N.C. 12 in Dare County to help the N.C. Department of Transportation move ahead with a short-term solution to protect the critical coastal highway from frequent ocean overwash caused by high winds and strong surf.

The declaration comes at the recommendation of Transportation Secretary Tony Tata, following a visit and town hall meeting along the Outer Banks on March 11. The governor and secretary surveyed the area and talked with residents about having a more reliable route between Hatteras Island and the mainland.

“The people there have real concerns about the road they depend on to get to work, school or medical appointments,” said Governor McCrory. “They need a highway that is not forced to close every time a storm approaches. By declaring a State of Emergency, NCDOT can fast-track work to rebuild the beach along the S-Curves, so we can keep the road open until a long-term solution is in place.”

A series of storms, including Hurricane Sandy last fall, resulted in severe beach erosion along N.C. 12 at the S-Curves.

NCDOT has already executed an agreement with the U.S. Army Corps of Engineers to nourish the beach along the S-Curves. NCDOT is currently working closely with the N.C. Department of Environment and Natural Resources to swiftly acquire the permit needed to conduct the work. The target date to begin beach nourishment is mid-to-late spring.

NCDOT has also acquired $20.8 million in Hurricane Sandy emergency response funding from the Federal Highway Administration to pay for the beach nourishment. The one-time emergency response effort will fortify the section of N.C. 12 most often threatened by powerful winds for three years by which time a permanent solution should be built.

“We know this work can’t wait. N.C. 12 is an important pipeline for visitors who have a major impact on the local and statewide economy.” Secretary Tata said. “We want to ensure residents get the help they need now as we continue to look for innovative and strategic ways to make a lasting impact.”

At this time, NCDOT is considering two long-term solutions for the S-Curves, a roughly one-mile section of N.C. 12 just north of Mirlo Beach. They include a bridge within the existing easement and a 2.5-mile bridge that extends into the Pamlico Sound. The department will hold public meetings about the options this summer and plans to award a contract for construction this fall.

In early March, strong winds pummeled the Outer Banks, causing significant overwash at the S-Curves and forcing the road to close on and off temporarily for more than a week. NCDOT crews have reopened the road and are now in the process of replacing the sand that blew off the sandbags installed after Hurricane Sandy last year.

A Drudge of a Dredge

As of right now, no work is going on N.C. 12 at Mirlo Beach because of a mechanical issue with the dredge pump.  The pump is not generating enough pressure to keep its lines from clogging with sand.  A part needed to fix the issue has been ordered and will be shipped overnight.  The repair is expected to be made tomorrow.

The dredge is the large red piece of heavy equipment in background

The gap between the sandbags placed at the north and sound ends of the highway is now approximately 100 feet wide.  Our engineers calculate that it will take 200 sandbags to fill in the gap. However, crews can’t resume the sandbag installation until the malfunctioning dredge is fixed.  The dredge is used to remove water and sand from the work site and sand collected by the dredged is then used to fill the sandbags.

Tomorrow, the plan is to begin hauling sand from Avon to fill in the trench between the sandbags and edge of the road. This will take approximately two days. Once the trench is filled, it will protect the edge of the road any overwash  gets through the sandbags. The trenches need to be filled before crews can begin covering the sandbags with sand to rebuild the dunes.

Weather on Friday will be windy with an “ugly”ocean.   Winds reaching 20-30 miles per hour could batter the Outer Banks starting Thursday night  and continuing into Friday. High surf driving by swells of 8-11 feet could become an issue, depending on winds and high tides.  

By the Numbers: Progress!

Over the weekend, N.C. Department of Transportation crews continued working on the temporary solution to reconnect all traffic on Hatteras Island to points north of Mirlo Beach.

Between Friday, Dec. 7 and Sunday Dec. 9, crews filled and placed approximately 160 sandbags along a 0.4-mile section of N.C. 12 at the S-Curves just north of Rodanthe on Pea Island. As of Sunday evening, crews have placed 456 of the 1,800 sandbags needed to create a protective barrier between the ocean and the road. Once all of the sandbags are in place, crews will rebuild the dunes on top of the sandbags.

Crews brought in 495 truckloads of sand from the sand pit in Avon to fill sandbags, build up the dunes and assist with rebuilding the roadway.

In addition, crews installed survey stakes in the road bed in preparation for grading, prior to repaving. All sections of damaged pavement were removed over the weekend. After sandbags are installed at the most heavily damaged parts of the highway, crews will begin rebuilding the road where it was located before the series of storms hit. All work is heavily dependent on the weather and tidal conditions.

Crews hope to open the newly paved lanes of N.C. 12 to all traffic on or by Dec. 25. Until then, four-wheel drive vehicles must continue to pass through checkpoints at the temporary bridge on Pea Island and at Mirlo Beach to travel between Hatteras Island and the mainland. 

We know it's interesting, but...

....we don;t want anyone to get hurt in the NC 12 work zones.  Not in your cars.  And not on foot.  We've had some folks venturing out to take pictures of the work, to get a higher view, etc. But as interesting as it it, with all the heavy equipment out there, and the debris and deep sand  it's just not safe.  We know you understand.  Thanks!

NC 12 Plan Q&A

Q&A about Hurricane Sandy Recovery Efforts along N.C. 12

We’ve gotten a variety of questions about our recovery plans along N.C. 12 in Dare County. We want to answer those questions, so you can better understand why we’re doing what we’re doing.

Q: Why are you rebuilding N.C. 12 in the same place?

A: We’re rebuilding N.C. 12 in the same location at the S-Curves, because it is the fastest way to restore access from Hatteras Island to the mainland. We know it hasn’t been easy for residents and visitors to use the emergency ferry route and the four-wheel drive route to get where they need to go. That is why we’re committed to reopening the highway to all vehicles as quickly as possible. Our goal is to have traffic flowing on N.C. 12 on or by Dec. 25.

Q: Are you considering beach nourishment at the S-Curves?

A: Yes. Beach nourishment is currently under consideration as we work to rebuild and reopen N.C. 12 near Mirlo Beach. We’re working with the U.S. Army Corps of Engineers to evaluate this option. No final decision has been made yet.

Q: Can you put down mats on the four-wheel drive route?

A: It is possible to put mats on the soft sand; however, they will only stabilize the route for four-wheel drive vehicles. The mats will not provide a surface stable or level enough for all-wheel drive and two-wheel drive vehicles. Therefore, we have chosen at this time not to use mats, because they would not greatly enhance the level of service we can provide, and they would take a great deal of effort to maintain.

Q: Can you put down gravel on the four-wheel drive route? Why not pave the four-wheel drive “sand road” and put dunes to the east of it?

A:  If we put down gravel or asphalt on the four-wheel drive route, we would be creating a permanent structure on Pea Island that is not inside our property lines. To do that, we would need to get special approval from a number of regulatory agencies. In addition, if we built a road on a new location, we would also need to build a temporary bridge at the overwash area to ensure access during storms. These combined steps would take far longer to implement and open to traffic than our current plan of rebuilding N.C. 12 in the same location, which should be complete on or by Christmas Day. Our goal is to reopen the highway as quickly as possible.

Q: Do you have long-term plans for the S-Curves?

A: Yes. In Rodanthe, the department is considering two options. The first one includes elevating N.C. 12 onto a bridge within the existing easement, which would end just north of the community center and not require beach nourishment. The second option is constructing an approximately 2.5-mile bridge that would extend into the Pamlico Sound and connect back to Rodanthe just north of the community center. These long-term solutions are currently moving through the environmental planning process required by the state and federal governments. We plan to award a contract for construction in the fall of 2013.

We Have a Date!

Calm weather conditions have prevailed in Dare County and our crews have made significant repairs to N.C. 12 and we are now able to move to the next step - a   temporary solution to reconnect all traffic on Hatteras Island to points north of Mirlo Beach. This will be a multi-step process that will include installing sandbags, reconstructing dunes, and rebuilding the road near Rodanthe where Hurricane Sandy and a pair of Nor’easters damaged the highway.

What's Happening Now
Crews are currently placing 15-foot-long sandbags along a 0.4-mile section of N.C. 12 at the S-Curves just north of Rodanthe on Pea Island. In all, 1,800 new sandbags will go in to create a protective barrier between the ocean and the road. Once the sandbags are in place, we'll rebuild the dunes on top of the sandbags.

At the same time, broken pavement will be hauled off from this section of N.C. 12. After sandbags are installed at the most heavily damaged parts of the highway, crews will begin rebuilding the road where it was located before the series of storms hit. And as you know, all work is heavily dependent on the weather and tidal conditions.

Weather permitting, we hope to open the newly paved lanes of N.C. 12 to all traffic on or by Dec. 25. Until then, four-wheel drive vehicles must continue to pass through checkpoints at the temporary bridge on Pea Island and Mirlo Beach to travel between Hatteras Island and the mainland.

Motorists are reminded that any private vehicle larger than a one-ton truck cannot use the route in order to protect access and allow traffic to flow more efficiently. In addition, private trucks with trailers are not permitted. Two-wheel drive vehicles are not allowed on the route under any circumstance.
More information on N.C. 12 recovery efforts is available on our N.C. 12 Recovery webpage and N.C. 12 Facebook page. For the latest details on the emergency ferry route, as well as schedules for our regular ferry routes, call 1-800-BY-FERRY and press 1, or visit the NCDOT Ferry page.

Updates: Temporary Bridge, Rodanthe and The Emergency Ferry

What's Happened? What's Next?

Paving 
As you may know, paving at the temporary bridge was completed yesterday.  Replacement of guardrail is the only remaining work there and that should begin today or tomorrow.  A temporary signal with a one lane traffic pattern will be in place at the temporary bridge until the guardrail is completed.

Paving of the repaired spans on Bonner Bridge were completed on Monday.
 
In an effort to reduce the length of the closed areas that have to be managed, Dare County is moving the checkpoints south of the temporary bridge.  

All other work with the exception of guardrail at the temporary bridge is complete.

S-Curves
At Rodanthe, sandbag installation continues along the east side of NC 12.  The contractor is working from south to north.  Additionally, removal of damaged pavement is set to begin on Monday. 

Monday Ferry Schedule Note
  
On Monday, Dec. 3, the 10 p.m. emergency ferry departure from Stumpy point to Rodanthe will be delayed so that a davit cable for the lifeboat on the Motor Vessel Hatteras can be replaced.  More details.

UPDATE: 4WD Access Opened Ahead of Schedule!

Our crew completed the maintenance work on the four-wheel drive access detour two hours ahead of schedule and it is now open to traffic!

Big, big kudos to the folks out there who worked hard to shore  up the access detour!

NOTE: The weight restrictions on the 4WD access that were initiated Tuesday ARE still in place.

4WD Closure set for Thursday

The large amount of traffic using the four-wheel drive access route on NC 12 at the S-curves, as well as the condition of the sand is forcing us to close the road tomorrow so that crews can  increase the stability of the sand on the north end of the route.  

The maintenance will also help reduce the likelihood of overwash on the access route as well. 

The four-wheel drive access will be closed Thursday, Nov. 29, from 9 a.m. to 4 p.m.

The traffic volume and sand conditions also forced NCDOT crews to implement vehicle size and weight restrictions.

Since the four-wheel drive route along N.C. 12 on Pea Island opened, a number of vehicles have gotten stuck in the sand and required a tow truck to get them out. This not only causes delays for the other vehicles using the route, but it also damages the makeshift road.

To help protect access and make traffic flow more efficiently, NCDOT is no longer allowing any vehicle larger than a one-ton truck to use the route. In addition, trucks with trailers are not permitted. Two-wheel drive vehicles are not allowed on the route under any circumstance.

Vehicles who do not meet the weight requirements and/or vehicles with trailers are becoming stuck in the sand, and this causes unnecessary back-ups as tow trucks and heavy equipment remove them.
 
Those of you who can use the route - please remember - the ride will be rough as you will be traveling over sand, damaged pavement and some water. On the sandy portions of the route, please follow lane markers.

Other important safety measures to take on the four-wheel drive access:

• Only drive four-wheel drive vehicles with a high ground clearance. Cross-over four-wheel drive vehicles that are lower to the ground may get stuck in the rugged terrain;
• If you drive at night, use extreme caution. There will are no lights staged along the route, so your vehicle’s headlights will offer the only way for you to see;
• Drive slowly;   
• Pay close attention to the temporary traffic signals; and
• All four-wheel drive vehicles are encouraged to lower tire pressure to minimize the chances of becoming stuck.

New Weight Limits for 4WD Access

Since the four-wheel drive route along N.C. 12 on Pea Island opened, a number of vehicles have gotten stuck in the sand and required a tow truck to get them out. Sunday alone, 49 vehicles had to be towed. This not only causes delays for the other vehicles using the route, but it also damages the makeshift road.

To help protect access and make traffic flow more efficiently, NCDOT is no longer allowing any vehicle larger than a one-ton truck to use the route. In addition, trucks with trailers are not permitted.

Now that it's calmed down a bit...

Over the Thanksgiving holiday, the wind, tide and overall weather situation calmed down some and if you're a regular follower of our Facebook page or Twitter account, you know the four-wheel drive access has not been closed quite as frequently.

Four-wheel drive access on Friday, Nov

While surf conditions have calmed considerably,  normal tides are still at the edge of the old road. Traffic through the holiday weekend was very heavy over the four-wheel drive access, which was able to remain open through high tide on Saturday and Sunday.  Today at Rodanthe sandbag installation began at the south end. 

 

So, with the improving weather, what's next?  

  

Our engineers are out looking at the trouble spots today and tomorrow, and are evaluating options.  As soon as details are available we will let you know. 

We've also had some questions regarding other issues related to NC 12, beyond the S-curves/Rodanthe trouble spot:

 

Bonner Bridge: Paving is expected to take approximately one day.  Once that's finished, the crews will then move down to the temporary bridge to begin work.

Signal timing @ temporary bridge: The timing of this signal will not be changed. There was more traffic over the holiday.  Things should be back to a more ‘normal’ rate this week. Also, paving will begin at this site tomorrow and the temporary signal might be replaced with flaggers during paving hours. 

  

Four-wheel Drive Access times: Dare County Sheriff’s Department is escorting vehicles until 10 p.m. Safety and traffic volume are the main reasons for the 10:00 p.m. closure time.
