Architectural Master Plan

One Framework for 100 Acres

The high-level plan for Gateway South: how the district reconnects to the city, what each zone does, and the order it gets built in.

District Framework

Reconnect, Preserve, Build

Once a connected mixed-use district, the area was gradually isolated from downtown and nearby neighborhoods by major rail and highway infrastructure. The plan stitches it back into the city and puts its industrial infrastructure back to work.

Restore the Grid

Re-establish the historic street grid, reconnecting the riverfront to downtown, Soulard, and LaSalle Park.

Preserve & Reuse

Prioritize preservation of heritage buildings and celebrate the site’s working industrial character.

Rail as Public Spine

Use the historic rail corridor as the district’s central spine, linking production, public spaces, events, and everyday movement.

Reach the River

Lookouts, bridges, and boardwalks connect the district physically and visually to the Mississippi.

Character Zones

Three Zones: Make, Meet, and Innovate

The Innovation Core concentrates walkable, mixed-use energy at the north end; the Manufacturing Core puts production at scale on the rail and river to the south. Between them, the Cultural Core is the district’s meeting ground, and transition zones knit all three into the neighborhoods behind them.

North

Innovation Core

Adaptive-reuse workshop, lab, and office space, planned for offices and incubators, prototyping labs, university partnerships, showcase galleries, and street-level retail.

The Meeting Ground

Cultural Core

The district’s shared civic and community center: public space, art and events, childcare and workforce training, connecting the Innovation and Manufacturing Cores.

South

Manufacturing Core

Manufacturing and distribution at scale, with rail access and a planned river port: storage and assembly yards, green buffers, and showcase space that lets the public see building happen.

Phasing

Built in Reinforcing Stages

The district grows incrementally: each phase activates the next, from renovation of what stands today to full build-out.

Phase 1 · Underway

Renovate & Activate

Rehabilitate heritage buildings, deliver the first new industrial facilities, and establish the district’s training, childcare, and employer ecosystem. Targeted by the end of 2027.

Phase 2

Expand the Working District

Add manufacturing, commercial, education, research, and workforce uses across the district, building on the infrastructure and partnerships established in Phase 1.

Phase 3

Grow a Mixed-Use Neighborhood

Introduce housing, retail, hospitality, cultural uses, and public spaces as the district’s employment base and daily population grow.

Phase 4

Complete Build-Out

Roughly 4.9 million square feet across industrial, office and lab, education, residential, retail, hospitality, and civic space.
