A £58m plan to solve traffic problems at one of the Midlands' busiest motorway junctions will be unveiled to the public later this month.
The Highways Agency is running an exhibition for the bypass scheme at M40 junction 15 in south Warwickshire.
The publication of an Environmental Statement over the weekend has started the statutory objection period.
The two-day exhibition at the Warwick Hilton Hotel on the A429 Warwick Road, near Warwick, starts on 21 July.
Visitors can see the plans for a new dual-carriageway over the M40, linking either end of the A46 - from the Warwick bypass towards Stratford.
The scheme includes a new bridge over the M40 and a roundabout south of the motorway, plus two new underpasses.
Highways Agency project leader Jonathon Pizzey said: "We hope people will come to the exhibition where they can see the plans and put questions to the project team about the scheme and its environmental implications.
"We have worked closely with local authorities and agencies to develop the plans to this stage."
People can make comments on the scheme in the statutory objection period running until 16 September.
The agency said it will then respond to queries and objections and aim to resolve them. A public inquiry could be held early next year.
