Facility Overview

The Weldon Spring Commuter Lot is a vital public park-and-ride facility located at the crossroads of Interstate 64 (US-40/61) and Missouri State Route 94 in Weldon Spring, MO. Operated and maintained by the Missouri Department of Transportation (MoDOT), this expansive open-air surface lot provides seamless vehicle staging for daily regional commuters, carpoolers, and outdoor enthusiasts visiting the scenic St. Charles County river corridor. The parking area features a well-laid-out, single-level asphalt surface with wide drive aisles and clearly painted stall striping, ensuring smooth two-way navigation.

Because it is an open-air surface facility without overhead clearance bars, roof canopies, or ceiling restrictions, the lot offers unlimited vertical headroom. It comfortably accommodates passenger cars, full-size pickup trucks, large commercial SUVs, rooftop-cargo carriers, high-roof conversion vans, and vehicles outfitted with bicycle racks. Generous turning radiuses throughout the parking lot also make maneuvering and reversing effortless even for long-wheelbase vehicles.

Visitor & Driver Tips

As a state-managed MoDOT commuter lot, parking is available at no cost on a first-come, first-served basis, meaning you never need to download paid parking apps like ParkMobile or SpotHero. While spaces are generally plentiful, arriving before 7:15 AM on Tuesday through Thursday guarantees the closest stalls to the entrance during the peak morning commuting period.

For those meeting weekend biking or hiking groups, remember that Missouri conservation regulations apply in nearby trailheads; please lock your doors and stash all valuables out of sight inside your trunk. When leaving the lot during the evening rush (4:30 PM – 6:00 PM), westbound traffic exiting I-64 onto Route 94 can build up quickly, so exercise caution and follow traffic signals carefully when turning back onto the highway.
