The Iowa Department of Transportation is urging motorists not to travel on Highway Two in southwest Iowa, between Iowa and Nebraska. The DOT said Saturday, that traffic is limited to one lane in each direction on the bridge over the Missouri River.

Earlier, only one lane was open. Drivers had been waiting for more than an hour for the bridge to clear so that traffic from their side of the river could cross.

Highway 2 is just north of Hamburg, which has built a second levee to contain floodwaters. Officials say Interstate 29 near Hamburg, remains closed.
