Drivers face a 40-mile detour due to a 60-metre broadband roadwork closure in Cockshutt, Shropshire.
Locals fear rising fuel costs and business losses, with some criticizing Freedom Fibre for poor communication.
The closure, set for March 16, may extend beyond the stated one-day period, with additional restrictions from March 24.
Freedom Fibre insists access will be maintained, but residents remain frustrated.
