Motorists faced extra headaches on Monday when they were diverted the wrong way up a new one-way system.
Cambridgeshire County Council and Wisbech Town Council have altered the flow of traffic around the town’s Market Place.
The traffic flow was reversed with drivers only able to enter the town centre via Church Terrace and Hill Street.
But on Monday morning, drivers were faced with a new challenge due to a diversion put in place by UK Power networks.
A county council spokesman said: “The utility company was given approval to carry out work and a new traffic management plan agreed which reflected the new one-way system.
“The implementation of the traffic management while the works are ongoing is down to the utility company. Unfortunately the company seems to have used their old plans and as soon as we were made aware on Monday the signs were removed and the company is changing the system to what had been agreed.”
Wisbech postmaster Ray Wicks said the traffic situation was ridiculous on Monday.
He said: “It had been chaotic but it has been calmed down.
“We need enforcement as the parking bays are not being used correctly.
“They also need to look at the phasing of the traffic lights.”
A map has now been released to illustrate the changes.
Calls were also made last week for the county council to have done more to warn drivers of the changes.
The spokesman said: “We understand some people might be uncertain of the changes. However, there is new signage in place to guide drivers around the town centre. We have also been working with the police on enforcing the new system.”
