(WTAQ-WLUK) — Seven flyover ramps in Northeast Wisconsin will see improvements.
Gov. Tony Evers signed a $6.87 million contract to improve six flyover ramps on I-41 in Brown County and one flyover ramp in Winnebago County.
Work begins July 7 on six Green Bay structures and is expected to finish this year. Work on the Winnebago County ramp is expected to take place in 2027.
This work will include long-term closures of ramps.
Project location
I-41/I-43 interchange, Brown County:
- Northbound I-41 to southbound I-43 southbound (over Velp Avenue)
- Northbound I-43 to southbound I-41 (over I-41)
- Northbound I-43 to northbound I-41
I-41/WIS 32/WIS 29 interchange, Brown County:
- Southbound I-41 to westbound WIS 29 (over WIS 29)
- Eastbound WIS 29 to northbound I-41 (over I-41/WIS 29)
- Northbound I-41 to westbound WIS 29 (over I-41)
Winnebago County
- Northbound I-41 to northbound US 45 (over I-41)
Project improvements include milling a portion of the deck, performing deck repairs, and overlaying with a polyester polymer concrete (PPC) overlay at the six interchange flyover ramp bridge overlays that are in Brown County. There will be a polymer overlay at the I-41 and US-45 system interchange ramp in Winnebago County in 2027.
Overall, two-lane ramps will remain open during the day with lane closures, and single lane ramps will be closed and detoured. There may be temporary evening and overnight full closures for repair work. Lane closures may cause delays during peak travel times.

The projects will:
- Longer-lasting infrastructure: The new polyester polymer concrete (PPC) overlay will significantly extend the service life of these critical flyover ramps, reducing the need for major replacements in the coming decades.
- Lower long-term costs: Proactive preservation now means fewer and less expensive repairs in the future, saving taxpayer dollars over time.
- Smoother more comfortable rides: The repaired and overlaid decks will create smoother driving surfaces, improving comfort and traffic flow for thousands of daily commuters and travelers.
- Improved safety: A restored, durable deck surface will provide better traction and a safer driving environment, especially on these high-traffic ramps.
- Advanced, high-performance materials: This project uses Polyester Polymer Concrete (PPC), a modern and more durable overlay technology that outperforms traditional thin polymer overlays. It is especially well-suited for busy flyover ramps that experience heavy traffic and harsh Wisconsin weather.
