A new weight limit intended to stop heavy lorries using a busy Lynn road has not been implemented because contractors have taken three months to make and install the signs.
County roads chiefs say the delay is partly down to the need for an electrical connection to the signs, which they hope to install this weekend, in Loke Road.
But the wait has been criticised by councillors and residents, who say they fear it will not solve their problems.
People living in Vancouver Avenue, Tennyson Road and Tennyson Avenue first raised their concerns about the impact of large lorries using the roads in their area with Norfolk Police chief constable Simon Bailey in January.
A public consultation then followed on the county council’s plans to introduce a 7.5 tonne weight restriction on vehicles using Loke Road.
Officials believe that will stop drivers using the area as a shortcut.
But, although the consultation finished in mid-March, signs warning drivers of the restriction have only just been completed and the order has yet to be formally implemented.
County councillor Alexandra Kemp, who has backed residents’ calls for action, branded the delay as “shocking.”
She said the authority’s contractors had been told to get the signs ready three months ago.
She added: “Traffic circulation round Lynn should be a top priority. This delay is completely unacceptable.”
A county council spokesman yesterday said it was hoped that the signs would be installed this weekend, before the order is formally brought into force.
She said the need for the signs to have an electricity supply connection, so that they can be illuminated, meant that some delay in the process was “unavoidable”.
But Vancouver Avenue resident Alan Clark said more should be done to tackle that and other traffic issues, particularly speeding, in the area.
He said: “I’ve been living here for the best part of 45 years and it’s just getting worse.”
Residents have also called for the Loke Road weight restriction to be extended along the entire length of the route.
And Mr Clark said “it remains to be seen” whether the proposals would help him and his neighbours.
