Lincolnshire County Council is preparing to renew its highways maintenance contract worth £762m.
Spread across three lots covering highways work, design works and traffic signals, the contract will run for six years from April 2020.
There is an option for this to be extended for a further six years.
The highways work lot will cover minor works including potholes; surfacing works; structure maintenance, which includes bridge replacement and repair; emergency response to deal with incidents; winter services including pre-salting highways; and street light maintenance.
The design works lot will comprise major and minor schemes, while the final traffic signals lot covers maintenance and repairs of signals.
Lincolnshire County Council expects to appoint one company to each lot.
Before procurement formally begins, the council will hold a meet the buyers event where it will look to hear feedback from potential bidders.
The event will take place in Lincoln on 18 May, with tendering for the new contracts expected to start on 16 July.
The new deal will replace the Lincolnshire Highways Alliance that was formed in April 2010.
Dynniq, Kier and WSP (formerly Mouchel) carried out maintenance under this deal.
