The Bonner Bridge links mainland Dare County with Hatteras Island.
It was shut down from December 3-15, 2013 after North Carolina’s Department of Transportation deemed the level of scour, or erosion, had reached a critical level.
An emergency repair project around Bent 166 of the bridge where the majority of the erosion has occurred was completed in February.
That work included placing more than 200 sandbags and 980 concrete a-jacks around Bent 166 to stabilize it.
On Monday, crews with NCDOT performed a mobile scan of the bridge that will allow them to monitor movements of the bridge.
On Tuesday, one lane of the bridge was closed as work continued with additional stabilization efforts.
That work will address Bents 162 to 165 of the bridge to prevent scour from reaching critical levels.
The $1.8 million project will place sandbags around the pilings and in between the bents and is expected to take three months to complete, as long as the weather cooperates.
A replacement bridge has been planned for years, but construction has been halted by lawsuits.
