Work has started on a large quarry despite concerns about increased traffic on a busy road from the future development.
Farmland off Holt Road in East Beckham, near Sheringham, will be turned into a gravel and sand extraction site and a new access will be constructed off the A148 Cromer to Holt road.
The 14.5ha site was approved by Norfolk County Council in April last year and Field Dalling firm Gresham's Gravel will develop and run it over 17 years.
Gresham's Gravel will fund A148 safety improvements, including a ghost island to allow traffic to turn right into the site as well as widening visibility from the new access.
The new quarry access will be close to where Holt teenager Martha Seaward was killed, after crossing the A148 and being hit by a lorry in January last year.
Her mother Karen Seaward, from Coronation Road, Holt, said the new junction would be a concern.
She claimed county council highways' concerns for the value of life was 'non-existent' as the safety at Lodge Hill junction, where her 15-year-old daughter died, had not yet been improved.
A county council spokesman said road safety was a key concern for the authority.
Anthea Sweeney, district councillor for the area, said: 'I am not happy about it. There are plenty of problems on the road as it is, with so many junctions. In the summer there is so much traffic. I'm very concerned.
'If anything goes wrong, like the Martha Seaward death, it takes months until anything is done about it.'
The new access off the 50mph road is close to a junction with Holway Road, which goes into Sheringham, and a layby. It is also on a hill.
The quarry will only become operational once the ghost junction is built and entrance visibility improved.
Work is due to finish at the end of May and new road warning signs will also be put up around the quarry.
