Even without this latest incident, driving an RV through the gorge would not be a pleasant chore. In the spots where there is only one lane open in each direction I think the lanes are only 12 feet wide with a wall on both sides.
This is from the website BEFORE the latest incident:
This area will have lowered speeds, with a 40-mile-per-hour limit in Tennessee and a 35-mile-per-hour limit in North Carolina. Vehicles over 8½ feet in width will not be allowed to use this roadway. Motorists must remember that this remains an active work zone in both states, with reduced lane widths to protect workers rebuilding the interstate in Tennessee and North Carolina.
In addition, motorists also need to be aware of the following:
The work zone extends from MM 446 in Tennessee to MM 7 in North Carolina.
There is only one lane of traffic open in each direction across approximately 12 miles.
Work crews and construction equipment will enter and exit this roadway daily.
There are no shoulders and no emergency pull-off lanes within the work zone.
There are no exits in the work zone with easy access to gas stations or convenience stores.
