Sometimes you need a view from above to really appreciate the progress of a project! These drone photos show the new interchange and highway relocation project just north of Janesville.
The first photo looks southeast at the new overpasses and the roundabout at the intersection of the southbound on/off ramps and 260th Street.
The next photo is taken from the opposite side looking north, and the last is from the south end of the project near Janesville, also looking north. In the last picture you can see the new Easton Avenue taking shape on the right side of the images, along with the interchange in the distance.
We’ve included a project diagram for reference as well. The contractor hopes to shift traffic to a head to head pattern in the current northbound lanes by the end of June/early July. They plan to have the new interchange completely open to traffic by mid-December. As always, those dates are weather permitting.

✅ Major Milestone Reached on the Iowa 3 Bridge in Downtown Waverly!

After 12 hours of steady work, crews completed a major step in the bridge construction: pouring the new deck.

🚚 93 truckloads of concrete were delivered and placed using two pumps at three locations, totaling just over 814 cubic yards.

To put that in perspective—that’s enough concrete to build 2.5 miles of 5-foot wide, 4-inch thick sidewalk!

👷‍♂️ What’s next? Crews will begin forming and pouring the barrier rails on both the north and south sides of the deck starting next week.
