A £1.9 million road designed to ease traffic chaos around Birmingham’s NEC has never been used by a single vehicle.
The road was completed last July but has yet to open because Solihull Council is waiting for electronic signs to be delivered from Germany.
The local authority built the road on the NEC site to cope with traffic from large shows such as Crufts, Horse of the Year and the Good Food Show.
The slip road is less than a mile long and links Station Way and Bickenhill Lane with the A45.
Currently there is just one route taking all traffic from Birmingham International train station, the airport, the NEC and the business park to the A45 Coventry Road.
The new road was built with an £11 million Department for Transport grant which Solihull Council received to improve public transport links across the borough.
Judi Turner, who works for a financial services company on the business park at the NEC site, said: “We were thrilled when they started building the road because it’s badly needed.
“There are a couple of companies on this site, all with lots of employees, and when we leave for the day when the big shows are on we sit in our cars at the island for half an hour because the traffic is so bad.
“It took them two years to build this road and when it was finished last summer we couldn’t wait for it to open.
“But we’ve been waiting and waiting and it is still closed.”
Mrs Turner rang the council to ask when the road would be opening but was told it was awaiting signs from Germany.
“This week it’s Crufts, which we’re dreading, because that’s the biggest show of all and the traffic will be horrendous,” she said.
“How can it take so long to get a couple of road signs?”
A Solihull Council spokesman said the slip road was part of a Department for Transport project improving access to the NEC and airport by public transport. He said although the road was completed last July, the council was still waiting for the signs, but denied the project had been “delayed”.
“There has been no delay with signage for any part of the project – the signs being installed are not traditional road signs, they are electronic signs that can flash up different pieces of information for road users,” he said.
“The whole project has been phased in over a number of years and had a number of elements that need to be in place before it can be completed.
“The signs, which are part of a larger signing contract covering the approaches to the area, are currently being manufactured and should be installed by March 31.”
He added: “The project has been phased in over a number of years and has a number of elements that need to be in place before it can be completed.
“The slip road between Station Way and Bickenhill Lane will help improve the flow of traffic in the area and will complement the improved public transport links.”
A spokeswoman for the Kennel Club, which organises Crufts, said it was disappointed the road was there but not operational.
“With more than 140,000 visitors and close to 28,000 dogs and their owners expected at Crufts this week, we would hope that the new road will provide welcome assistance in getting people into the car parks as efficiently as possible in years to come,” she said.
“However, the NEC has always worked hard to provide the most efficient traffic management and no doubt will be well prepared for our visitors this year.”
The NEC said it welcomed the road but was well-equipped to deal with the extra traffic created by big shows even without it being open.
Andrew Melville, NEC operations manager, said: “We work closely with the Highways Agency and police to ensure congestion is kept to a minimum at busy times. And with our extremely experienced on-site team of traffic officers the management of our roadways are tailored accordingly to ensure all visitors have a fantastic experience at shows.”
