Horace Wilkinson Bridge
The Horace Wilkinson Bridge (locally known as the New Bridge) is a cantilever bridge carrying Interstate 10 in Louisiana across the Mississippi River from Port Allen in West Baton Rouge Parish to Baton Rouge in East Baton Rouge Parish. Around the Baton Rouge metropolitan area, the bridge is more commonly known as the "New Bridge" because it is the younger of the two bridges that cross the river in Baton Rouge, downstream of the older Huey P. Long Bridge.
