MADISON, WI (WTAQ) - If you’re having trouble getting Wisconsin travel information on the Internet, you’re not alone.

The state DOT says its Web-based travel information systems were down overnight, because an upgrade is taking place on the network. As a result, Internet camera images, freeway overhead signs, and estimates of travel times on the freeways might be sporadic Friday morning.

The DOT said its technical staff worked all night so the outages would be as short as possible.

Meanwhile, those who monitor traffic can still see real-time video – and they’re working with law enforcement when necessary. And as usual, the DOT is sharing information on its 511WI Twitter accounts for its 5 regions of the state.
