Drivers are facing long delays in Chesterfield town centre because of work to fix a roof.
One lane of Holywell Street, outside Eyres furniture shop, is currently closed.
A spokesman for Derbyshire County Council said: “The lane closure is to allow scaffolding for access to repair a damaged roof.
“The closure is due until Thursday.”
Drivers have contacted the Derbyshire Times to complain that the work was causing road “carnage”.
