Situated on once vacant and underutilized land, PlayPort represents the first implementation project within Phase 4 of Waterfront Park - an 85-acre urban park that has transformed former industrial wastelands along the banks of the Ohio River into one of Louisville, Kentucky's most beloved public spaces, attracting more than 2.4 million visitors annually. While the first three phases of Waterfront Park were completed by 2013, East-Coast based landscape architecture firm MKSK established a vision in 2016 through the Waterfront Park Phase 4 Master Plan to extend the park westward and reconnect communities that had historically been separated from the waterfront.

Developed through a close collaboration between MKSK, the Kentucky Science Center, Waterfront Park, and local stakeholders, PlayPort celebrates Louisville's industrial heritage and deep-rooted relationship with the Ohio River through a one-of-a-kind play experience. Located across the historic "9th Street Divide" - a physical and social boundary that has long separated Louisville's West End from economic investment and opportunity - PlayPort was envisioned as a destination attraction and neighborhood asset. Today, nearly 3,000 households can access the site within a fifteen-minute walk, creating a highly accessible recreational resource for an area that has historically lacked significant public investment that would contribute to social and economic revitalization.

Built For Community
Through a series of workshops, youth-focused visioning sessions, public meetings, and interactive design exercises, local residents helped shape the project's direction. One particularly successful activity invited children to "build their own play experience" using physical models and creative storytelling. These sessions revealed a strong desire for adventure, exploration, climbing, and opportunities to interact with large-scale objects and equipment. Rather than relying on standardized play components, the design team used these insights to create an environment in partnership with the Kentucky Science Center that encourages imagination and discovery. The project seamlessly integrates learning opportunities into every aspect of the site, inviting users to confront challenges through a risk-reward balance of physical obstacles and STEM-based experiences that introduce principles of engineering, physics, mechanics, navigation, construction, and river ecology through hands-on interaction. Climbing structures reveal concepts of balance and force. Pulley systems demonstrate mechanical advantage. Observation points encourage exploration of the river ecosystem and industrial landscape. The result is a setting where curiosity naturally leads to discovery.

 

A Historic Foundation
The site's history became a powerful source of inspiration throughout the design process. Long before becoming vacant land, the area played a significant role in Louisville's development as one of the city's earliest settlements. For generations, this stretch of riverfront was a gateway for commerce and transportation along the Ohio River. The riverfront evolved alongside the city, supporting shipping operations, industrial manufacturing, steel fabrication, rail infrastructure, and river-based commerce. Each era left behind physical traces and stories that contributed to Louisville's identity as a working river city.

The concept for PlayPort emerged from the idea of creating 'play out of work', a place where children could experience and interact with the equipment, materials, and artifacts that once defined the site. To accomplish this, the team embarked on an extensive search for authentic industrial and maritime artifacts. Boneyards, salvage yards, decommissioned river operations, industrial storage facilities, and construction equipment suppliers throughout the Ohio River corridor were explored in search of unique elements that could be safely adapted for play. The team identified and acquired an extraordinary collection of salvaged artifacts, including a full-sized excavator, a massive dump truck bed, industrial scooper buckets, maritime buoys, chains, towboat components, crane structures, and many more. Each artifact was carefully evaluated, modified, and integrated into the design, allowing visitors to interact directly with authentic pieces of the region's past. The result is a landscape that functions simultaneously as playground, outdoor museum, science center, and community gathering space.

The River
The park is organized around three major play zones - The River, The Big Dig, and The Overlook - each inspired by a different chapter of Louisville's relationship with the Ohio River and each providing a distinct play and learning experience. The River celebrates Louisville's maritime history and the role of the Ohio River as a transportation corridor. Here, children interact with authentic shipping and navigation artifacts, including shipping containers, buoy tenders, crane jibs, industrial pulleys, and river-related equipment. The large Buoy Tender boat, based on an actual Coast Guard ship that can be regularly seen traveling up and down the Ohio River, encourages imaginative role play, allowing visitors to become river captains, dock workers, engineers, and explorers. Integrated educational opportunities teach visitors about river navigation,
commerce, ecology, and the significance of waterways in shaping cities and economies.

The Big Dig
The Big Dig draws inspiration from the site's industrial and construction heritage. This area transforms large-scale construction equipment into an extraordinary play environment unlike anything found in a traditional playground. Children can climb on excavators, scramble up boulders and slide down the bed of an oversized dump truck bed, navigate giant tires that can be spun around on their axles, scramble through box culverts, and interact with machinery that would normally be inaccessible. The experience encourages physical activity while introducing visitors to concepts related to construction, infrastructure, engineering, and problem-solving. Artifacts associated with the nearby lock and dam, and canal system provide additional opportunities to learn about how human ingenuity has shaped the Ohio River and supported regional growth. The scale of these features creates a sense of wonder and adventure, allowing children to engage with industrial history in a tangible and memorable way.

The Overlook
The Overlook offers a completely different experience focused on elevation, exploration, and perspective. Situated adjacent to the interstate and overlooking the river, this area features a dramatic observation structure that invites visitors to climb through a series of cage tunnels, transfer platforms, ramps, and stairways. As visitors ascend, they gain new perspectives of the river, downtown Louisville, and the surrounding landscape. The elevated experience fosters a sense of adventure while remaining accessible to users of varying abilities. The upper platform serves as a flexible space for outdoor education, science demonstrations, performances, and community events. It also functions as a place of reflection and observation, reinforcing the connection between the city and the river that made its growth possible.

Full Steam Ahead
More than a playground, PlayPort is a community investment, an educational resource, and a celebration of Louisville's identity. Community leaders, educators, elected officials, and neighborhood residents have embraced PlayPort as a transformative addition to Louisville's West End, recognizing its ability to foster pride, connection, and opportunity. Its success has further validated the broader vision established in the Waterfront Park Phase 4 Master Plan, with additional phases now advancing through fundraising and implementation efforts.
