Bonner Bridge over Oregon Inlet near Nags Head, NC

(Bridge Hunter)
I thought this1962 bridge was made with concrete girders until I looked at Bridge Hunter. It uses steel stringers.

The work on the new $246 million bridge reminds me that satellite images are about a year old. The replacement bridge is about half done and should complete in 2018. [Update] Design for the new bridge was done in 2011. But environmentalists delayed construction until a groundbreaking on March 8, 2016. [Groundbreaking] Rodanthe citizens were complaining about the extra cost to address environmental costs. [Protest] My reaction is that people should not have been allowed to live on the outer banks in the first place. That is, even the first bridge should not have been built.

A video of the replacement construction indicates the bridge is higher with fewer piers. I assume the height is to get it above storm surges. They stated that fewer piers are used so that they can afford to make them deeper to better withstand sand erosion.

I saved a satellite image because it includes an ocean going boat. I find it interesting that the propwash is about as long as the ship itself. It must be going rather fast considering how close it is to the bridge. The captain must be confident in his "aim." Or maybe it is easier to steer more accurately with a strong flow past the rudder.

It must be the winter time because I found only three cars on it in the satellite image. A Street View shows a boat and only one car. This is the first bridge I have seen that seems to have more boat traffic than auto traffic. But a Google Photo shows that it does have a lot of traffic sometimes. I assume the busy time is in the Summer.

  1. Thanks for posting. I used to camp at the NPS campground at Oregon Inlet as often as I could.There is a sport fishing launch there but I think that ship is part of the dredging about 1000ft astern. As for living there, tons of tourism pretty much sustains the whole coastal region. Plus, Wright Bros first flight, Roanoke Colony,ship graveyard, Blackbeard....
