LDA Engineering partnered with the City of Johnson City to transform two miles of West Walnut Street from a blighted industrial corridor into a vibrant, multimodal connection between East Tennessee State University and downtown. The $33 million redevelopment introduced a protected cycle track, wider sidewalks, raised intersections, traffic-calming features, improved transit stops, urban landscaping, a pedestrian plaza, and a new stormwater park.
Working within a constrained 60-foot right-of-way, the team navigated historic buildings, active businesses, shallow rock, high groundwater, and century-old infrastructure. More than a dozen utility systems were coordinated and modernized while maintaining uninterrupted water and sewer service. Improvements also included large-diameter stormwater infrastructure, permeable pavers, underground electrical service, and a dual 42-inch railroad bore.
Today, West Walnut Street is a safer, more walkable, and more connected corridor that has helped attract new restaurants, retail, housing, and private investment. More than a roadway project, it demonstrates how thoughtful infrastructure can strengthen mobility, support economic development, and create a more resilient community.
The West Walnut Street Corridor Redevelopment Project transformed a blighted industrial corridor into a vibrant, multimodal gateway connecting East Tennessee State University and downtown Johnson City. Completed under highly complex conditions—including a narrow 60-foot right-of-way, century-old utilities, shallow rock, and active businesses—the $33 million project required precision engineering and seamless coordination. The result is more than infrastructure: protected bike lanes, expanded sidewalks, pocket parks, stormwater innovations, and underground utilities create a safer, greener, people-focused corridor. Already spurring private development and civic pride, the project stands as a model of visionary design, technical excellence, and long-lasting community impact.
