The morning commute was smooth, according to green bay police.
With the fog and bridge closure it did take people longer to get where they were going.
That includes thousands of drivers who used the Leo Frigo to make a living.
"I am just worried that something is going to happen" says Mike Vizer, the terminal manager for St Marys Cement.
Every day dozens of trucks come to fill up at his dock in the port of Green Bay.
Now the Leo Frigo bridge detour is taking them through the heart of downtown.
"It is going to be a hassle for a lot of our drivers and customers. We do have some that come from that side of town, they either have to come all the way around the city or come through downtown which in my opinion is going to be dangerous" Vizer says.
The corner of Broadway and Dousman has a particularly tight turn for semi truck drivers. In bumper to bumper traffic sometimes they have no option but to take the curb.
It is adding to damage on city streets, causing the curb to break down in several spots.
"The drivers are going to be as safe as they can it is just going to take patients from everybody to deal with the extra traffic" Vizer says.
Semi drivers we spoke with say the closure is adding at least a half an hour to their trip, cost that could eventually be passed on to the consumer.
"It is a lot slower, going through town with all the stop lights" says professional driver Andy Hansen.
"Police are helping out quite a bit by detours and stuff so it has been alright" says Paul Bettine another professional driver.
Other drivers can help the big rigs by stopping well before the cross walk which gives them ample room to turn on narrow city streets.
"Drive safe, keep your concentration, just be alert out there" reminds Bettine.
Police have asked the Department of Transportation to consider reaching out to the rail companies to time their trips through downtown around rush hour so the situation does not get worse.
Officers are already adjusting timing at stoplights to help with traffic flow.
Finally, Green Bay Police say if you can avoid this detour, do so. Try Mason Street which was built to handle heavier traffic.
