The world class sailing venue is due to be completed in November
Residents are being invited to examine plans to improve transport in Weymouth ahead of the 2012 Olympics.
The Weymouth Transport Package will be displayed with the Weymouth Relief Road exhibition at Weymouth and Portland Borough Council offices this week.
Some £18m has been set aside for improvements before the Olympic sailing events in Weymouth and Portland.
Dorset County Council will submit a business plan to the Department for Transport by the end of the year.
'Better traffic management'
Mike White, the local authority's strategic projects manager, said: "Ahead of a more detailed consultation on the package in spring 2009, we want to update residents with where we are in the process and remind the community what the project aims to achieve.
"The 2012 Games has given us a unique opportunity to tackle some of the major problems for public transport in Weymouth and Portland.
The relief road is set to relieve congestion on the A354 and A353
"Plans include improving the rail and bus interchange at the train station, improving bus services, with fleet and bus stop improvements, and better traffic management through junction improvements."
Both exhibitions demonstrate part of the Integrated Transport Strategy for the Dorchester-Weymouth-Portland corridor, a council spokesman said.
Work on the relief road to Weymouth and Portland - due to start early next year - is expected to be complete before the area hosts the sailing events.
Campaigners, including the Campaign to Protect Rural England (CPRE) and Transport 2000, said the route would cut through the legally-protected countryside and would affect the ancient woodland and a nature reserve.
But the county council has the support of many local residents and businesses who said their daily lives and commercial activities were blighted by traffic congestion on the main road into the seaside town.
