What Are the Parking Garages at BWI Airport and Where Are They Located?

BWI Marshall Airport has five distinct on-airport parking facilities, each at a different location around the terminal loop. According to official airport data, the total on-airport capacity is approximately 22,000 parking spaces across all facilities. Here is where each one sits:

• Hourly Garage — Directly attached to the terminal. Enter from Aviation Boulevard (MD Route 170). Walk straight into the terminal — no shuttle required.
• Daily Garage — Adjacent to the Hourly Garage, also on Aviation Boulevard. A short walk or free shuttle connects you to the terminal. Closest option after the Hourly Garage.
• Express Parking — Located on Scott Road, near the Cell Phone Lot, close to the intersection of I-195 and Aviation Boulevard. Requires a free shuttle to the terminal.
• Long-Term Lots — The farthest on-airport option. Accessed via the terminal loop road. Free shuttle runs every 10–15 minutes (every 25 minutes between 1–5 AM).
• BWI Rail Station Garage — Located at the BWI Amtrak/MARC rail station. A free 24/7 airport shuttle connects the garage to the terminal.

The primary access road to BWI is Interstate 195, which connects directly from I-95. Travelers coming from Annapolis use Interstate 97, and those from D.C. typically take the Baltimore-Washington Parkway (MD-295). Signage along all major approach roads directs drivers to specific parking facilities. Before you leave home, check real-time traffic on Waze — congestion on I-95 or I-195 can add significant time to your drive.

The Cell Phone Lot is free and located on Scott Road directly across from Express Parking. Drivers waiting to pick up arriving passengers can wait here for up to one hour at no charge. It is not a parking garage but is a critical part of the BWI parking layout to know.

BWI Airport Parking Garage Map: Level-by-Level Layout Guide

The BWI airport parking garage map is best understood by splitting the facilities into two groups: the attached garages (Hourly and Daily) and the remote lots (Express, Long-Term, Rail Station). The official BWI parking page offers a downloadable PDF map, but the text layout below gives you a working mental map for each structure.

Hourly Garage — Level-by-Level

The Hourly Garage is a multi-level structure attached directly to the terminal building. Each level is typically labeled by a letter or color section (A through D or similar zone designations). The ground level connects directly to the terminal's lower-level arrivals area. Upper levels feed into sky bridges or internal walkways that connect to departures. If you park above the ground floor, follow the interior signage toward the elevator banks, then cross the sky bridge to the terminal's departures level. The smart parking guidance systems being rolled out in 2026 will display real-time space counts per level — look for the overhead LED indicators as you enter each floor.

Oversized vehicles — including large SUVs, trucks with roof racks, and cargo vans — may not fit in the Hourly or Daily Garages due to height clearance restrictions (see the dedicated section below). Plan accordingly before you arrive.

Daily Garage — Level-by-Level

The Daily Garage sits adjacent to the Hourly Garage and shares a similar multi-level structure. From any level, follow the internal walkway signs toward the terminal connector. At ground level, a direct walkway reaches the terminal. On upper levels, use the elevators to reach the sky bridge connection. The Daily Garage is a strong choice for trips of one to three nights because the $16/day flat cap keeps costs predictable. ADA-accessible spaces on the lower levels are clearly marked and closest to the elevator banks.

Express Parking, Long-Term Lots, and Rail Station Garage

These three facilities are surface lots or lower-profile structures rather than multi-story garages. Express Parking on Scott Road is an outdoor lot — park, note your row and space number (take a photo), then catch the free shuttle at the marked pickup point. Long-Term Lots are the largest facility by capacity and are organized into clearly marked sections. Again, photograph your space number and the bus stop number before walking to the shuttle pick-up area. The Rail Station Garage is a structured garage at the Amtrak/MARC station — park here and the free 24/7 shuttle takes you directly to the terminal.

How Much Does BWI Airport Garage Parking Cost? (Hourly, Daily, and Long-Term Rates)

BWI on-airport parking rates are set by the Maryland Aviation Administration (MAA) and have been in effect since July 1, 2024, the first rate increase since 2009. Here is every on-airport rate side by side (checked on bwiairport.com in October 2026):

The Hourly Garage is only cost-effective for short visits of about two hours or less ($12 for two hours). At three hours it costs $18, more than the Daily Garage at $16/day, and Express Parking at $14/day is cheaper still with a predictable flat rate. For multi-day trips, the Long-Term Lots at $11/day are the cheapest on-airport option. For a full breakdown of per-day costs by trip length, see our guide to BWI airport parking per day rates for every lot.

BWI accepts cash, Visa, Mastercard, American Express, Discover, and contactless payments at all parking facilities. You do not need to pre-book on-airport parking — walk-up rates apply at the gate. However, off-airport providers typically require advance booking online to secure the advertised rate.

How Do You Get from the BWI Parking Garage to the Terminal?

The route from garage to terminal depends entirely on which facility you parked in. Each option has a different connection method — and the wrong assumption can cost you time.

• Hourly Garage → Direct internal walkway to terminal. No shuttle. Ground level connects to arrivals; upper levels use sky bridges to departures. Fastest walk-in option at BWI.
• Daily Garage → Walk via covered internal walkway, or take the free shuttle. Allow 5 minutes to walk, or 10–15 minutes if you wait for the shuttle.
• Express Parking → Free shuttle only. Walk to the marked shuttle bus stop in the lot, then ride to the terminal. Shuttle runs every 10–15 minutes (every 25 minutes between 1–5 AM).
• Long-Term Lots → Free shuttle only. Same frequency as Express — every 10–15 minutes. Add buffer time for early morning flights.
• Rail Station Garage → Free shuttle to terminal, runs 24/7. Or walk to the rail platform and take the MTA Light Rail directly to the BWI Marshall Airport station inside the terminal loop.

A practical tip that frequent BWI travelers use: photograph your space number and your shuttle bus stop number the moment you park. Both are posted on signs at the space and at the pickup area. This saves significant stress on your return, especially at night or after a long trip. The Long-Term Lots in particular span multiple sections, and finding your car without a reference photo is harder than it sounds.

Allow at least 30–45 minutes from parking to clearing security if you are in the Long-Term Lots or Express Parking — especially during peak travel periods. If you have TSA PreCheck, security lines move faster, but you still need shuttle time in your plan.

Which BWI Parking Option Is Best for Your Trip Length?

The best on-airport option depends directly on how long you are leaving your car. Here is a clear breakdown based on verified 2026 rates:

• Up to 2 hours: Hourly Garage at $6/hour ($12 for 2 hours), direct terminal walk, no shuttle delay.
• Same-day or overnight (1-2 nights): Daily Garage at $16/day or Express Parking at $14/day. Both cap your cost and are close to the terminal.
• 3-7 nights: Long-Term Lots at $11/day. At $77 for a 7-day trip, this is the cheapest on-airport option. The shuttle adds a few minutes, but the savings are meaningful.
• Any longer trip: off-airport lots on Triply undercut every on-airport option per day. Doubletree Baltimore at about $6/day comes to about $43 for a week, about 44% less than the $77 Long-Term total.

For a deeper comparison of off-airport lots versus on-airport options, our guide to BWI airport offsite parking covers every lot with current rates and shuttle details. Bookings on Triply come with free cancellation with a full refund up to 24 hours before check-in.

What Are the Height Restrictions and Special Rules for BWI Parking Garages?

Height clearance restrictions apply to the Hourly Garage and Daily Garage at BWI. These are enclosed multi-level structures with overhead clearance limits. Vehicles exceeding the posted height limit — typically marked at the garage entrance — cannot enter. This affects:

• Full-size pickup trucks with bed toppers or elevated suspension
• Large SUVs and minivans with roof-mounted cargo carriers or ski racks
• Cargo vans and full-size commercial vans
• Vehicles with roof tents or raised antenna systems

If your vehicle is oversized, use the Long-Term Lots or Express Parking instead — both are open-air surface lots with no height restrictions. The trade-off is a shuttle ride to the terminal, but there is no risk of being turned away at the entrance. Always check the posted clearance sign at the garage entrance before driving in. If you are unsure whether your vehicle fits, default to Express Parking or Long-Term.

Is There EV Charging or ADA Accessible Parking in the BWI Garages?

EV charging stations are available within BWI's on-airport parking facilities. Based on current airport data, charging is available in the Hourly Garage area. For specific station locations and charger availability before your trip, check the BWI charging locations on ChargeHub for real-time status. Charging technology upgrades are part of BWI's ongoing 2026 infrastructure improvements.

ADA-accessible parking is available in all on-airport garages and lots. Per official airport data, the closest accessible spaces to the terminal entrance are located in the Hourly Garage and Daily Garage. These spaces are clearly marked and situated near elevator banks for direct terminal access. If you need accessible parking and want to minimize walking distance, the Hourly Garage is your best option — it offers both ADA spaces and a direct walkway to the terminal with no shuttle required.

BWI also operates a free shuttle with ADA-accessible vehicles connecting the remote lots to the terminal. If you are traveling with mobility equipment or a wheelchair, notify the shuttle driver — they are trained to assist and the buses are equipped with ramps or lifts.

How to Save Money on BWI Airport Parking: Garages vs. Off-Airport Lots

The cheapest on-airport garage rate is $11/day at the Long-Term Lots. The five off-airport lots Triply sells at BWI run about $6 to $8/day, all below that. Only the Westin and Sheraton state a free shuttle, and shuttle hours differ by lot, so check the table. Here is how the on-airport and off-airport options compare side by side:

For a 7-day trip, Doubletree Baltimore saves you about $34 versus on-airport Long-Term: about $43 against $77, roughly 44% less. Its shuttle runs 24 hours, every 15 minutes from 5 AM to midnight. Even the priciest Triply lot here, Clarion Hotel BWI North at about $58 for the week, comes in below Long-Term. Free cancellation with a full refund is available up to 24 hours before check-in.

If you want the absolute best deal and do not mind a slightly longer drive from the highway, compare all five BWI off-airport lots at once. The BWI long-term parking coupon guide also covers current promo codes and discount strategies. On Triply, the off-airport lots run about $3 to $5 per day less than the $11/day Long-Term Lots.

A note on the $520 million Concourse A/B Connector — completed and opened January 9, 2026, this is the largest capital project in BWI's history. It added 142,000 sq ft of new construction and directly connects Concourses A and B without backtracking through the main terminal. This does not affect parking access, but it does mean a smoother experience once you are inside. Southwest Airlines passengers using Concourses A, B, and C will notice the improved flow.
