Every day, more than 55,000 drivers use the bridges at Wade Avenue and Peace Street.
At the meeting, people got a close-up look at some proposals for the area of Capital Boulevard that is really the gateway into and out of the north end of downtown.
The changes are leaving some businesses, like Finch's restaurant and Rollins Economy Cleaners, worried about their future. Each is in the shadow of the Peace Street Bridge.
In a new proposal to update the bridge, both would probably have to be torn down.
In all, the bridge replacement project will cost nearly $40 million. The City of Raleigh wants more elaborate interchanges with a cost of $54 million.
For now, all ideas are on the table for the public to review.
The public meeting was held at the Meymandi Hall Lobby at the Duke Energy Center for the Performing Arts.
Construction is planned for 2016 and it could take a couple of years depending on which option the DOT decides.
