Barriers designed to prevent cars from using a dedicated Lynn bus lane have been fixed, but not all buses are using the road.
The bollards at each end of the Hardings Way route have been reinstated, six months after they were taken out of service because of technology problems.
But, this morning, Stagecoach in Norfolk announced it was diverting its 46, 55 and 505 services, which normally use the route, along London Road until further notice.
However, commercial manager Will Smith said the company expected to run the services along their normal routes tomorrow.
He said: “We have suspended service due to transponder issues on board our vehicles and roadworks at the bottom of Millfleet which is making it difficult to proceed.
“This will only be a short-term diversion and normal service will resume from Friday 26th June.”
