WELCOME TO THE MAGNOLIA BRIDGE PLANNING STUDY DROP-IN SESSION
Talk with staff and share your feedback on 3 possible lower-cost alternatives for replacing the Magnolia Bridge.
Later this year, once a lower-cost alternative is recommended from the planning study, it will be presented to decision-makers alongside the cost and traffic impacts of the in-kind replacement selected through the 2002-2008 Magnolia Bridge Study.
