A “perfect storm” of traffic has hit Chicagoland:

The recent traffic backups aren’t a mirage, say transportation officials. It’s really a perfect storm of ongoing construction projects occurring at nearly all points of the expressway system. This includes the Jane Byrne Interchange project, the behind schedule and over budget construction job that offers one of the worst choke points for congestion in the heart of downtown Chicago…
The last week in September saw some of the worst traffic in recent memory, thanks not only to the ongoing construction — including the start of three-weekend lane reductions on Interstate 57 to accommodate ramp patching and resurfacing — but also an emergency closure of the outbound Dan Ryan Expressway ramp to the outbound Stevenson Expressway that isn’t expected to completed until Sunday, according to IDOT…
Transit experts say that Chicago, which has some of the worst congestion of any American city, is also grappling with its return to normalcy following closures brought on by the pandemic. The added congestion comes at a time when many workers such as Cavanagh are returning to the office after two years of work-from-home protocols. Rider usage of transit systems such as the Chicago Transit Authority, Metra and Pace also haven’t yet returned to normal…
“In other words, drivers are making more trips, but they’re shorter trips on average,” Dan Ginsburg, TTWN’s director of operations said in an email.
So the old joke in Chicago, “there are two seasons: construction and winter,” rings true again?
But, this is a bigger issue than just construction. The infrastructure needs help. More people are driving. People live and work in different locations. Mass transit is not being used much. Mass transit does not necessarily reach where it needs to reach. People want to drive faster. There is a lot of freight and cargo moving through the region and so on.
This “perfect storm” could be an opportunity to ask how to address traffic and congestion throughout the city and region for the next few decades? How will this get any better?
