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.

Kudos for the Ferries!

We are very proud of our Ferry Division and its staff for their efforts during and after Hurricane Irene, when Hatteras Island was cut off from the rest of the world because of damage to N.C. 12.

Last month, they were recognized for their dedication during the emergency by the U.S. Coast Guard.  The special commendation for Outstanding Humanitarian Response details the hurricane and the results of “widespread destruction” including the breaches on N.C. 12and how critical ferry service was during that crisis.


Congrats to all our ferry personnel!!

Workshops Slated to Discuss Design Options

Mark Dec.5 and Dec. 6 down on your calendars.  We're holding two workshops expressly to discuss the options for permanently fixing the breaches on N.C. 12 on Pea Island and Rodanthe caused by Hurricane Irene.
We need your feedback on the ideas and we'll use it to figure out the best long-term solution for each breach.
Here are the specifics on the meetings:
  • Monday, Dec. 5, from 4 p.m.-7 p.m.
    Dare County Administration Building
    954 Marshall C. Collins Dr.
    Manteo  

  • View Larger Map

  • Tuesday, Dec. 6, from 4 p.m.-7 p.m.
    Rodanthe-Waves-Salvo Community Center
    23186 Myrna Peters Rd. 
    Rodanthe

  • View Larger Map
Drop in any time between 4 p.m. and 7 p.m.. NCDOT representatives will be there to explain the design options and answer any questions. Share your ideas, thoughts and suggestions with us!


New Aerials!

We love it when our photogrammetry guys go flying!

Power to Pea

Cape Hatteras Electric Coop has begun receiving materials to construct a permanent transmission line at the Pea Island breach.

Permanent Solutions





NCDOT staff and partners met today to begin work on the long-term solutions for the section of N.C. 12 hard-hit by Hurricane Irene.

You can read more here about the session, but here are some of the options discussed:
For fixing the largest Pea Island breach:
  • Beach renourishment;

  • Constructing a bridge within the existing easement; and

  • Building a bridge or road on a new location.

For fixing problems areas near Rodanthe:
  • Beach renourishment;

  • Building a bridge where the road now stands; and

  • Constructing a bridge or road on a new location.

Some of the next steps in the overall process:
  • Holding a panel discussion with experts in the fields of coastal science and engineering to learn about the changes in conditions along N.C. 12 resulting from Hurricane Irene, identify issues and constraints associated with future maintenance of the highway, and provide engineering advice on design parameters for long-term solutions at the two breach sites;

  • Hosting public meetings to formally present the options to citizens, gather their input and answer their questions;

  • Providing all feedback to the Merger Team and securing support to begin the permitting process; and

  • Presenting a realistic, fundable, buildable design plan to Gov. Perdue.

The process to develop permanent solutions for the two breaches on N.C. 12 is a continuation of work already under way as part of the Bonner Bridge Replacement Project. Phase one of the project involves replacing the 2.7-mile bridge over Oregon Inlet, which is currently in the design stage. The project also includes an active coastal monitoring program that uses scientific data to determine what types of improvements are needed on N.C. 12 between Pea Island National Wildlife Refuge and Rodanthe and when that work will occur. Using this program, NCDOT will enact phase two of the project, which will permanently fix the areas damaged by Hurricane Irene.

Now What?


Now that the temporary bridge is done and N.C. 12 is open all the way down Hatteras, what happens next? Stay tuned to this blog, ncdot.gov and on Twitter @NCDOT_NC12 for updates and info on the next phase of the post-Hurricane Irene era for this iconic roadway.  In the meantime, we'll try to keep you updated on other events and news happening in and around the area.  Feel free to send us suggestions for how you'd like us to stay in touch!

It's next Tuesday!

Or maybe sooner!

N.C. 12 Update 10/05/2011 


 The N.C. Department of Transportation will reopen N.C. 12 no later than Tuesday, Oct. 11 after the road has been closed due to the damage caused by Hurricane Irene in August.

 “Our hope is to open before then, but right now we are confident work will be complete on or before the 11th”, said resident engineer Pablo Hernandez.  “We will open to road earlier if we can.”

 At the Rodanthe breach area, crews completed paving the asphalt base for the road patches south of the mid Pea Island breach and began grading the sand for the roadway embankment leading to the southern end of the bridge.

At the temporary bridge location on Pea Island, crews worked all night and into the early hours to set deck panels at the north end of the bridge after it was completely lowered onto the permanent bridge bearing supports.

The southern half of the bridge is in the process of being lowered onto the bearing supports. Crews still need to install six of the 12 bridge bearing supports, anchor the bridge in place and finish installing deck panels; however, the following items are complete at the temporary bridge location:

Piling: all 82 piles driven.
Sheet Piling Bulkhead: all 726 linear feet installed.
Concrete Footings: all 12 footings poured.
Bridge Truss Spans: all 662 linear feet placed.

Night Moves

The N.C. 12 temporary bridge crews worked all through the night and into the morning, lowering the north half of the bridge onto its permanent bearing supports, and setting deck panels, among other things.

Jack Under the Wood

This photo came in with this morning's batch from the site of the temporary bridge on NC12 and out of context it might look a little strange, if not precarious:

So, what's going on here?
·           
      Yesterday, our crews installed hydraulic jacks underneath the bridge truss and began lifting it in order to remove the temporary roller bearings used to extend the bridge across the breach.  The jacks will also be used to lower the bridge onto the permanent bearings.  This is a very delicate procedure where the bridge is alternately supported on wood blocks and lowered with the jacks approximately  four to six inches at a time.  Eventually, the bridge will be lowered approximately two to five feet, depending on the location along the bridge alignment.
