Plans to build a new motorway junction ahead of the construction of 1,600 new homes in Portsmouth are going on public display.
The city council wants to develop land at Tipner but wants to build a new junction off the M275 first.
The aim is to avoid construction traffic travelling through residential streets. Work could start in 2010.
Staff working on the plan will answer questions at Stamshaw and Tipner Leisure Centre on Friday and Saturday.
David Maxted, the council's project director for Tipner, said: "Quite understandably, residents will have concerns and opinions about the plan - especially people who live near the proposed junction.
"We've been talking to them for some time about plans for Tipner. This exhibition is an opportunity to look at the detail of the junction plan.
"We'll do our best to answer questions they may have, and they will have an opportunity to make their views known as part of the planning process."
The plans will remain available to view at the leisure centre next week.
The council and the South East England Development Agency (SEEDA) are in the process of submitting a planning application for the new junction.
Apart from new homes, of which 30% will be affordable, the council also wants to build a park-and-ride site at Tipner.
The whole development could create 1,500 jobs and "create an attractive modern gateway to the city", the council has said.
