A curious reader recently emailed the Johnson City Press, asking about the use for these devices that were recently installed as part of the intersection improvements in Boones Creek at Interstate 26.
We contacted Mark Nagi, the Tennessee Department of Transportationâs Region 1 community relations officer, to find out. Nagi quickly got back to us with the answer.
âThe devices are overhead detection warning systems. They are used to notify any vehicle that has a higher profile than the I-26 bridge over Boones Creek Road has, that they will not safely pass under the bridge,â Nagi said. âThey are placed at locations to allow these vehicles, once warned, ample time to exit Boones Creek Road prior to the underpass.â
Beginning Friday night, Boones Creek Road will be closed to traffic between the Interstate 26 interchange ramps until early Monday morning.
According to the Tennessee Department of Transportation, the road will be closed in the area under the interstate bridges from 10 p.m. Friday until 6 a.m. Monday.
On Monday, one lane of traffic will be open in each direction and this will be the final configuration for the project.
Businesses on either side of the interchange will be accessible.
Detour signage will be in place to direct traffic around the work zone.
This schedule is contingent on favorable weather conditions. Motorists are advised to use extreme caution in this area as workers will be present.
Overhead sign installation for the Interstate 26 interchange upgrade in Boones Creek will result in some lane and ramp closures in the project area beginning Sunday. All work is expected
