Zoo Interchange: Has Traffic Congestion Been Reduced?

The state of Wisconsin has spent a lot of money redoing the Zoo Interchange — and it wants to spend more. But has traffic congestion been reduced for commuters? And why does more work need to be done?

More work on the Zoo Interchange in Milwaukee County would take place if Gov. Tony Evers' state budget proposal goes through. The governor wants action on the far north end of the interchange, from roughly Swan Boulevard to Burleigh Street. 

Evers recently told news reporters that with the Zoo Interchange, declared complete last year by then-Gov. Scott Walker, the aim is to truly wrap up  the job.

"The north part of the interchange, the Zoo Interchange, needs to be finished, notwithstanding the claim last time that it was. It wasn't. So, we've still got a lot of barrels up there, we may as well finish the project," Evers said March 1, in Sturtevant.

But Republican legislators have been criticizing Evers' plans to pay for more road spending with a gas tax hike. So last week, the Wisconsin Department of Transportation (DOT), held a news conference at Children's Hospital in Wauwatosa. Milwaukee Regional Medical Center Director Bob Simi says finishing the Zoo Interchange's north leg would ease the minds of parents whose children need care at the hospital.

"You can imagine the level of anxiety the patients and the family members are experiencing, and how important it is, with this massive number of patients and employees to arrive here safely and quickly," Simi says.

He says 150,000 vehicles a day use the north leg, while more than twice that number use some part of the Zoo Interchange. It is a busy junction there, where Interstate-94 crosses with Interstate-41.

Dan O'Brien commutes every work day between his home and the Third Ward in downtown Milwaukee. He recently wrote to Beats Me, wondering whether the past few years of work on the Zoo Interchange have sped up traffic.

After a huge road construction projects—Zoo Interchange—does the department of transportation actually audit to see if traffic is improved?

"In all of those commutes, I avoid the freeway, almost at all costs, because before and after all the construction, it's still super slow," O'Brien says.

Michael Pyritz, communications manager for the DOT's Southeast Region, says there isn't much data yet on traffic congestion relief  in the — mostly — done Zoo Interchange.

"I avoid the freeway, almost at all costs, because before and after all the construction, it's still super slow," says Dan O'Brien.

He says there is more information, mainly on safety, on another huge reconstruction project that wrapped up a decade ago — the Marquette Interchange in downtown Milwaukee.

"We've seen better than a 30 percent reduction in crashes from before the project. You know, one of the benefits you get from that investment is getting an interchange built to modern standards. The Marquette Interchange, the Zoo Interchange were really designed back in the 1950s," Pyritz says.

After the Marquette was rebuilt, Pyritz says congestion persisted. So, the DOT reconfigured some lanes just west of the Marquette.

Pyritz says the congestion O'Brien mentions just east of the Zoo Interchange has to do with a delayed project, a proposed re-do of I-94 between 70th and 16th Streets.

"One of the challenges we have is we are incrementally building and rebuilding the system. So, we have a brand new modern heart, attached to 1950 arteries," he explains.

The Southeastern Wisconsin Regional Planning Commission (SEWRPC) also points to the delayed East-West freeway project. But Executive Director Kevin Muhs says even if that someday goes through, don't expect to always zip along. 

"If anyone's promising complete congestion relief, they're being dishonest," says Kevin Muhs.

"If anyone's promising complete congestion relief, they're being dishonest. But, we are hoping to maintain, long-term, the level of congestion we have right now, so the system doesn't get overwhelmed," Muhs says.

He says SEWRPC's prediction for the next 30 years is that traffic counts will continue to go up.

"We're expecting new people and jobs to come to the region. There will be more demand on the transportation system. More people will be driving on it, and that's going to create more congestion," Muhs says.

SEWRPC recommends a doubling of the investment in mass transit. The DOT says it also supports more transit options — and so does our Beats Me question asker O'Brien:

"It may be that we have to find ways to get cars off the road if we ever want to alleviate the congestion," O'Brien says.

The challenges, according to agencies like SEWRPC, are timing and finding the money.
