St. Louis Lambert International Airport Map (Most Up-To-Date)
St. Louis Lambert International Airport functions as two physically separated terminals with vehicle-only connections within St. Louis’s primary air-travel hub: Terminal 1 (long, linear curb) and Terminal 2 (compact box with a choke-point intersection). The overall layout is west–east along Lambert International Blvd, with Terminal 2 encountered first off I-70 Exit 238A, then Terminal 1 farther west. Groundside decisions happen early, and door numbers (Exit 12, Door 10, Door 15) matter more than “arrivals/departures” labels.
Map Table
| Terminal | Key Airlines | Primary Function | Transfer Mode |
|---|---|---|---|
| Terminal 1 | American, Delta, United | Concourses A, C • larger curb frontage | Terminal Shuttle: Exit 12 ↔ Door 10 • MetroLink via garage • no walk route |
| Terminal 2 | Southwest | Concourse E • highest O&D volume | Terminal Shuttle: Door 10 ↔ Exit 12 • MetroLink pedestrian bridge • no walk route |
St. Louis Lambert International Airport Map Strategy
- Commit early on I-70: Exit 238A decision + lane position determines whether you get forced into the Terminal 2 loop before you ever see a “Terminal 1” sign.
- Use door numbers as your primary coordinates: T1 Exit 12 for the terminal shuttle, T2 Door 10 for the shuttle pickup, T2 Door 12 for rideshare island access, T2 Door 15 for parking shuttles.
- Treat Terminal 2 Arrivals as optional during peaks: the fastest “curb win” is often meeting on Terminal 2 Departures (upper level) to avoid the lower-level stall points near the east-end doors.
- Run a clean recovery path if you miss the pickup: exit past the Terminal 2 curb, take the Air Cargo Road loop, turn around via the Cell Phone Lot/Lot E, then re-enter instead of getting pushed onto I-70.

Current STL wayfinding still hinges on the same structural constraints: Terminal 1 and Terminal 2 remain separated by non-walkable road and airfield buffers, and Terminal 2’s curb/approach intersection can gridlock during arrival banks. Door-number navigation (T1 Exit 12, T2 Door 10/12/15) stays the most reliable “map layer” for pickups, transfers, and recovery moves.

What is the exact driving path from I-70 to Terminal 1 Departures that avoids getting forced into the Terminal 2 loop?
Staying on Lambert International Blvd past Terminal 2 is the key move, because entering the Terminal 2 left-turn queue commits you to the congested loop and delays any Terminal 1 approach.
From I-70 West, take Exit 238A for Lambert International Blvd and immediately merge to the far-right lane on the ramp/service road. Continue straight on Lambert International Blvd with Terminal 2 on your left, ignoring the Terminal 2 signalized entrance. Stay on Lambert International Blvd for about 1.1 miles past Super Park and cargo areas, then take the signed split for Terminal 1 and follow the Departures (upper level) ramp to the Terminal 1 curb.
What is the exact driving path from I-70 to Terminal 2 Arrivals that avoids the departure-lane crossover choke points?
Using the lane marked for Arrivals and committing to the lower-level split immediately after the entrance turn reduces the forced weaving that triggers the Terminal 2 crossover stall.
From I-70 West, take Exit 238A for Lambert International Blvd and stay in the left or center lane so you can queue for the Terminal 2 entrance at the signal. As you turn left into the Terminal 2 complex, hold your lane through the turn (don’t swing wide), then take the immediate lower-level split for Arrivals by veering left/down. If the signal queue is not clearing through green cycles, use the rightmost approach lane to enter, then immediately take the ramp up to Departures and run the pickup on the upper curb instead of fighting the lower crossover.
Where exactly is the Terminal Shuttle pickup at Terminal 1 (Exit 12), and what is the shortest indoor walking route to it from the Ticketing/Baggage Claim area?
Exit 12 on Terminal 1’s lower (Arrivals) level is the Terminal Shuttle pickup point, and the shuttle stop sits on the first traffic island rather than the immediate sidewalk.
From the Terminal 1 baggage claim hall, move to the center of the carousel area near the Information Booth and locate the signed Exit 12 doors between Carousel 4 and Carousel 5. Go out Exit 12 to the curb, then cross to the first island where the “Terminal Shuttle” sign is posted. From ticketing (upper level), take the central escalators/elevators down to baggage claim, walk straight into the middle of the hall, then exit at the clearly numbered Exit 12 set.
Where exactly is the Terminal Shuttle pickup at Terminal 2 (Door 10), and what is the shortest indoor walking route to it from the baggage claim exits?
Door 10 on Terminal 2’s lower (Arrivals/baggage claim) level is the Terminal Shuttle pickup point, and it sits at the far west end of the curb line.
From Terminal 2 baggage claim, stay inside and walk west (left if you’re facing the curbside doors) past the last baggage carousel toward the international-arrivals end of the hall. Door 10 is the last numbered exit on that west end, near the Southwest Baggage Office, and the shuttle loads directly at the curb outside Door 10. If you exit the wrong door, re-enter immediately and walk inside to Door 10 rather than trying to navigate along the curb roadway.
At Terminal 1, where is Door #6 on the Departures level located relative to the main curb, and which indoor route gets you there from baggage claim with the fewest turns?
Door 6 is on Terminal 1’s upper (Departures) curb near the east end, positioned by the American Airlines ticketing area and the C-Concourse checkpoint zone.
From Terminal 1 baggage claim, go to the Carousel 6 area and take the nearest escalator or elevator up to the ticketing/departures hall. Turn right (east) and walk in a straight line along the counters toward the American Airlines section. Door 6 opens directly onto the departures curb beside those counters, and it is one of the last upper-level doors before the roadway begins to descend away from the curbline.
At Terminal 1 baggage claim, which specific exit/door-number positions give the best driver visibility for a curb pickup (so the driver can spot you immediately)?
Exit 17 on Terminal 1’s lower (Arrivals) curb gives the best driver visibility, because it sits toward the far west end where traffic thins and sightlines open up.
Exit 17 is closest to the Carousel 1 end of the baggage claim hall and is often signed for passenger pickup and car-rental shuttles, which keeps it less cluttered than the central taxi-heavy zone. Exit 14 is the second-best option for visibility because it’s more central, but it can be blocked by taxis and commercial vehicles. For the cleanest pickup, stand outside the doors at Exit 17 and stay curbside (not deep under the overhang) so an approaching driver can spot you earlier.
At Terminal 2, where is the Uber/Lyft pickup zone relative to the arrivals curb lanes, and what is the shortest walk from baggage claim to that exact curb point?
The Uber/Lyft pickup zone is on the traffic island across from the Terminal 2 arrivals curb, not on the door-side terminal sidewalk.
From baggage claim, head to the central exits near Baggage Carousel 3 and 4 and go out at Door 12. Cross the first roadway at the marked crosswalk to the median traffic island, where “App-Based Ride” signs mark the pickup point. If you’re standing at Door 12 on the terminal-side curb, you are one roadway short of the actual rideshare zone; move to the island so your driver can legally stop and see you without circling.
At Terminal 2, what is the exact escape route a driver can take to loop back for a second pickup attempt without re-entering the worst part of the curb queue?
Exiting past Door 15 and looping via Air Cargo Road is the fastest reset, because it avoids getting pushed onto I-70 and lets you re-enter Terminal 2 cleanly.
| Segment | What to follow | Landmark check |
|---|---|---|
| Leave the curb | Continue forward to the end of the arrivals curb | pass Door 15 at the east end |
| Commit to the exit | Follow the terminal roadway as it curves out | “Exit” flow away from the doors |
| Avoid the I-70 dump | Go straight/slight left toward Air Cargo Road | do not take the right that feeds I-70 |
| Turnaround point | Enter the Cell Phone Lot or Lot E entrance, turn around, exit back out | Cell Phone Lot / Lot E signage |
| Re-entry | Turn left to head back west on Air Cargo Road and re-approach the Terminal 2 entrance intersection | returns to the same signalized Terminal 2 entry node |
From Super Park (airport lot) shuttle drop-off at Terminal 2, what is the shortest indoor route to the Southwest check-in counters (by landmark sequence)?
The shortest indoor route is Door 15 → walk inside toward Door 12 → escalator up to ticketing → Starbucks landmark → Southwest counters on the west half of the hall.
Enter Terminal 2 through Door 15 on the lower level, then walk west inside the baggage-claim corridor toward the center doors (aiming for the Door 12 area). Take the first main escalator bank up to the upper ticketing level, where you emerge near the Starbucks on the landside hall. Turn left and continue along the counter line; Southwest check-in occupies the broad west side of the ticketing hall.
From Terminal 2 baggage claim, where is the exact curb location used for parking-lot shuttle pickups, and what is the shortest indoor route to that pickup curb?
Door 15 on Terminal 2’s lower (Arrivals/baggage claim) level is the primary parking-lot shuttle pickup curb, and it is at the far east end where shuttle buses stage and load.
From baggage claim, walk east (right if you’re facing the curbside exits) past Carousel 1 toward the end of the hall and exit at Door 15. Outside, the parking shuttles typically load along the outer curb/traffic-island side, which is why this door area becomes a stall point when multiple buses dwell. If Door 15 is jammed, re-enter and move west to a less congested exit (around Door 12) and coordinate a shuttle pickup only if your operator allows alternate stops.
From the Terminal 2 MetroLink station, what is the exact indoor walking route to the Terminal 2 ticketing/check-in area (including which entrance you emerge into)?
The MetroLink route enters Terminal 2 on the upper (Departures) level via the parking-garage pedestrian bridge, which puts you directly into the ticketing hall without needing elevators.
Exit the train at the Terminal 2 station and go down from the platform to the connected garage level (commonly signed toward Garage Level 3). Follow signs for the pedestrian bridge and walk across the enclosed bridge into the terminal. You emerge inside Terminal 2 near the east end of the upper departures level, where the ticketing/check-in hall opens immediately to your left. Continue left/straight along the hall to reach the main airline counters, with Southwest occupying the larger west side of the ticketing area.
If a passenger accidentally exits at the wrong level at Terminal 2 (Arrivals vs Departures), what is the shortest internal path to switch levels to the correct curbside pickup point?
The central escalator/stair bank just inside Door 12 is the fastest level switch, because it connects the lower baggage-claim corridor to the upper ticketing hall in about two minutes.
From the lower arrivals curb, go back inside through Door 12 (center of the curb line) and immediately look for the main escalators/stairs aligned with the center doors. Take them up to the upper ticketing level, where you come out facing the TSA checkpoint area; turn around and exit at Door 2 on the departures curb. From the upper departures level, reverse the same move: enter near Door 2, walk inward to the escalators by the center of the hall, and descend to the lower level, returning toward the Door 12 area.
At Terminal 2, where are the curbside pinch points/intersections that cause the line to stall, and what alternate curb entry point minimizes time trapped in the queue?
The main stall point is the Terminal 2 entrance intersection at Lambert International Blvd plus the east-end curb zone around Doors 14–15, where shuttle buses dwell and block the exit lane.
| Problem point | Where it happens | Alternate that reduces trap time |
|---|---|---|
| Signalized entrance choke | Lambert International Blvd at the Terminal 2 entrance turn | enter and immediately take the ramp up to Departures for pickup instead of committing to Arrivals |
| East-end curb blockage | Arrivals curb near Doors 14–15 | load earlier at Door 12, before the bus cluster |
| Curb-to-garage conflict | Lower-level lanes where cars queue while pedestrians cross to the island | use Departures level meeting (upper curb) to avoid the crossing zone entirely |
If you must transfer from Terminal 2 to Terminal 1 landside, what is the shortest walk from the Terminal 2 baggage claim exits to the Door 10 shuttle pickup, and where exactly do you arrive at Terminal 1 (Exit 12) relative to ticketing?
Door 10 to Exit 12 is the required landside transfer path, because there is no walkable Terminal 2 to Terminal 1 route.
From Terminal 2 baggage claim, stay inside and walk west toward the international-arrivals end, passing the last baggage carousel and the Southwest Baggage Office area. Exit at Door 10 (far west end) and board the Terminal Shuttle at the curb directly outside that door.
The shuttle arrives at Terminal 1 on the lower (Arrivals) level at Exit 12, centered in the baggage claim hall between Carousel 4 and Carousel 5 near the Information Booth. Ticketing is one level up: the quickest move is the elevator/escalator bank near the center of the hall, which brings you into the middle of the ticketing counters upstairs.
