(LOUISIANA)--Potential sites for a new Mississippi River bridge at Louisiana are being unveiled.

The Missouri Department of Transportation is hosting a public forum from 5 to 6:30 p.m. March 21 at the Twin Pike Family YMCA. Displays, maps and information about each location will be available, and the public will have a chance to vote on its favorite.

The state wants input on the good and bad of several proposed routes, one of which will be chosen next year.

The 85-year-old Champ Clark Bridge is one of the oldest and narrowest on the river between Minnesota and Tennessee.

An environmental study for a new bridge already is under way. Still to be answered are questions such as where the state will find 100 million dollars for the project, when construction could begin and whether the new span will be two-lane or four-lane.
