Update: I just heard from Milwaukee County Supervisor Pat Jursik, who said work on College west of Pennsylvania is expected to be complete by December. And be prepared: A roundabout is indeed planned on College at Ace Industrial Drive.
In case you haven’t noticed, College Avenue west of Pennsylvania Avenue is now closed to through traffic, setting up a frustratingly long detour around the airport using Layton Avenue to the north or Rawson Avenue to the south.
This happened in the last couple of days, and I’m not quite sure what the current timeline is for the project.
Of course, work on College east of Pennsylvania/Nicholson also continues, so that whole stretch is kind of a mess. But think of how it will look when it’s done!
I am working to find out more details and will keep you posted. In the meantime, please be patient around the delays.

I work downtown and have stopped taking 794 due to the construction. I’m taking the old Lake Drive route through Cudahy/St. Francis/Bay View. You can jump back on 794 at the more civilized on ramp at Howard, or wind your way through Bay View and Walker’s point.
This detour only adds about 10 minutes to my commute and beats being stuck at the top of the Hoan as it bounces around in the wind and traffic.
I, and so many people, have complained about the horrible and deteriorating condition of College Ave., and am so glad it is being repaired and upgraded. Everyone who ever uses it once the work is done will be so happy with the results. So a little inconvenience now will definately be worth it in the long run. Also, signs have been posted on College for weeks announcing the closure. We all just have to add a little extra travel time to our schedules.
