MILWAUKEE (CBS 58) -- If road construction in Milwaukee is affecting your commute, a Milwaukee alderman has a warning. 

"We're about to see a dramatic adverse impact from the closing of a major arterial street in Milwaukee," Ald. Robert Bauman said. 

He's talking about the state's plans to shut down the 27th St. viaduct over the Menomonee Valley.

He points out that the 16th St. viaduct is already closed due to construction, which means that anyone who wants to drive straight across the valley can't do it between 6th and 35th streets -- a distance of about two miles. 

"That'll put a tremendous amount of traffic through neighborhoods, residential neighborhoods, through side streets," Ald. Bauman said. "An immense amount of left turn movements, right turn movements, and it'll become complete chaos. It could add half-hour, 40 minutes to a typical trip crossing the Menomonee Valley."

Ald. Bauman wants the state to delay the 27th St. shutdown, and he's asking Milwaukeeans to write to the governor since this is a state project. 

The closure is currently scheduled to begin Feb. 2. 

We've reached out to the Department of Transportation for a response to the alderman's complaint, but we have not yet heard back.
