A stretch of road in the north of the county will close this month to carry out repairs to a railway bridge.
Gretton Road, between Gretton and Harringworth, will be closed for two weekends between 10pm on a Saturday and 4pm on a Sunday.
The closures will take place on September 9/10 and 16/17.
This will have an effect on some visitors to the dog show and sponsored dog walk in Harringworth on Sunday, September 10.
A signed diversion will be in place and the show will still take place.
