The North Carolina Department of Transportation (NCDOT) has announced the anticipated reopening of Interstate 40 between North Carolina and Tennessee, following severe damages caused by Hurricane Helene. Slated for January 1, the reopening will bring relief to travelers, although the route will operate under modified conditions to ensure safety. With over a mile of the eastbound lanes washed out, traffic through the Pigeon River Gorge will be limited to one lane in each direction on the westbound side, creating a narrower passage than the interstate standard. This restriction reduces lane widths to 11 feet, leading to a lowered speed limit of 40 mph for added caution.
Efforts to stabilize and reinforce the westbound lanes have been a priority. Contractors are working under an $8.5 million stabilization contract set to conclude by January 4. Key to this plan is the use of a concrete barrier in the middle of the westbound lanes to create safe passage while leaving enough space for reconstruction on the eastbound lanes. Wanda Payne, NCDOT’s Division 14 Engineer, emphasized that, while conditions may be tight, patience from motorists will be essential for smooth travel through the modified stretch.
For approximately nine miles — with five in North Carolina and four in Tennessee — I-40 will function as a two-way corridor, a setup that Tennessee already implemented last month on their section up to the last exit within the state. The two-way traffic will remain in effect until contractors finalize plans and designs for the eastbound lanes. According to Payne, multiple strategies are under review, and the best long-term solution will be selected collaboratively.
Damage to I-40’s eastbound lanes stemmed from severe flooding along the Pigeon River on September 27, which scoured the banks and destabilized the road in about ten spots in North Carolina, with additional sections in Tennessee also impacted. To secure the westbound lanes, contractors have employed “soil nailing” — a technique involving driving steel rods into bedrock beneath the road, grouting them for adherence, and applying concrete to the cliff face. This process reinforces the roadbed, allowing safe passage despite the compromised terrain.
The reopening of I-40 will also see dedicated tow trucks stationed along the gorge to assist with any vehicles that may break down or encounter issues within the narrower lanes, minimizing further disruptions. Although the journey through the Pigeon River Gorge will be slower and potentially prone to backups, it marks a significant improvement in accessibility for both locals and freight transporters.
Additionally, Hurricane Helene’s impact extended to other crucial routes. Interstate 26, which also connects North Carolina and Tennessee, was severely affected after two bridges collapsed over the flooded Nolichucky River. However, as of October 30, Tennessee’s Department of Transportation has constructed a temporary causeway over the river, restoring limited access on I-26.
