For McMahon, 2025 was a year of meaningful progress. From reimagining public spaces to improving transportation, supporting education and fostering community bonds, McMahon has been proud to play a role in shaping stronger, more connected communities. Here’s how 2025 unfolded:

Reimagining Public Spaces

Libraries are more than just books — they’re a hub for collaboration, creativity and learning for all ages. This year, McMahon helped plan the transformation of the Neuschafer Public Library and Community Center in Fremont, Wisconsin, into a modern, welcoming space for everyone. With thoughtful design and spaces for all ages, this project is a shining example of how public spaces can bring communities together. Learn more about the library project here.

McMahon is proud to have partnered with the Wolf River Development Company to bring the Wolf River Office Building to life in Keshena, Wisconsin. This three-story facility is a testament to intentional design and functionality, blending professional spaces with features that serve the broader community. The upper floors house the Wolf River Development Company and a financial group, while the first floor features a multi-purpose training room, a retail coffee shop and incubator spaces to support local startups.

In the Town of Westville, Indiana, McMahon donated the design, layout, engineering and even the project plaque to two new lighted pickleball courts at Prairie Meadow Park. It’s a powerful example of what’s possible when public and private partners come together to invest in the community.

Enhancing Transportation Infrastructure

By focusing on efficient design and functionality, McMahon’s transportation projects are helping communities stay connected.

The County J interchange in Kaukauna is now open to traffic, featuring upgrades to the bridge over I-41, ramps and roundabouts. McMahon was selected to provide the construction engineering services for the project. 

In the Town of Neenah, the reconstruction of Larsen Road is now complete, featuring a full roadway rebuild, widened shoulders, a new trail on the south side and stormwater management improvements. This significant upgrade enhances safety and accessibility, providing long-term benefits for both drivers and pedestrians alike.

Protecting Community Health and Sustainability

In 2025, McMahon also turned its attention to essential but often invisible infrastructure, designing comprehensive upgrades to the wastewater treatment facilities for the Village of Morton in Illinois. By modernizing the wastewater facility in this growing region, McMahon’s work embodies our commitment to community, public health, environmental stewardship and long-term sustainability.

• Elementary STEM remodels
• Einstein Middle School remodel and addition
• James Madison Middle School remodel and addition
• Appleton East High School remodel and addition

Supporting Local Growth

VerHalen, Inc. is now operating out of its brand-new headquarters in the Town of Lawrence. McMahon provided civil and structural engineering design and construction administration for the 90,000-square-foot facility, which includes offices, a showroom and warehouse space to support VerHalen’s distribution across the Fox Valley, Green Bay and beyond.

In fact, the Town of Lawrence continues its rapid development with McMahon’s Matt Greely serving as the town’s civil engineer. Read more about how the area has become a major manufacturing and industrial corridor in Northeast Wisconsin.

Inthe Town Westville, Indiana, McMahon contributed to the growth and improvement of utilities and wastewater treatment. With Phase 1 completed in 2025, McMahon looks forward to watching the community grow and thrive as it completes Phase 2 in 2026.

The completion of the new pedestrian and golf cart bridge at Road America marks another phase in McMahon’s longstanding partnership with this iconic venue. Designed to enhance accessibility and improve the overall visitor experience, the bridge allows seamless movement for both pedestrians and golf carts. Learn more about this project here.

Additionally, 2025 saw McMahon become the Official Engineering and Architecture Firm of Road America solidifying a great partnership with the iconic racing organization for years to come.
