Eddie Fellows from construction provider, Amey, has defended the decision to close the tunnels in Birmingham city centre for highway maintenance.
He says it is essential maintenance which is being done at the quietest time of the year.
Cameras from ITV News Central went inside the St Chad's and Queensway tunnels to see the work going on there.
The A38 St Chad's and Queensway tunnels through Birmingham are now closed - and will stay closed for six weeks until September 2nd.
