Facility Overview

The Union Station PEX Lot, located at 2020 Clark Avenue in downtown West St. Louis, is a versatile open-air surface parking facility serving the iconic St. Louis Union Station entertainment complex and the surrounding sports and civic corridor. Situated just south of the historic train sheds and grand terminal hall, this paved surface facility provides spacious, ground-level parking that eliminates the anxieties associated with tight multi-story parking ramps. Because it is an outdoor lot with no overhead barriers or ceiling restrictions, the PEX Lot comfortably accommodates all vehicle types, from compact sedans and sports cars to full-size pickup trucks, passenger vans, and high-profile SUVs with roof cargo boxes or bike racks.

Prime Location & Nearby Attractions

Strategically positioned at 2020 Clark Avenue, this lot places visitors in the heart of top-tier entertainment, dining, and athletic action. It serves as direct on-site parking for all primary attractions within the Union Station complex, including the St. Louis Aquarium, the 200-foot-tall St. Louis Wheel, the Carousel, Mini Golf, the Mirror Maze, and the St. Louis Union Station Hotel (Curio Collection by Hilton). For sports enthusiasts, the facility is within an easy 5 to 7-minute walk (approx. 0.3 miles) to CITYPARK stadium, home of MLS franchise St. Louis CITY SC, situated right up 20th and 21st Streets.

Visitor & Driver Tips

Due to high regional popularity, particularly during CITY SC home games, Blues matches, holiday events like The Polar Express Train Ride, and weekend festivals, this lot often switches to special-event flat-rate parking that can sell out early. Visitors are strongly advised to reserve parking passes in advance via digital booking platforms to guarantee a spot. When approaching via I-64, take the 20th Street or 22nd Street exit for the quickest route to Clark Avenue. Make note of your parking space number or row upon arrival, and allow an extra 10-15 minutes when leaving immediately following major sell-out sporting events.
