Honestly, driving to Baltimore/Washington International Thurgood Marshall Airport (BWI) is a bit of a gamble if you don't know the rhythm of the DMV. One minute you're cruising down I-295 with the sun hitting the trees, and the next, you’re staring at a wall of brake lights near the MD-100 interchange because a ladder fell off a truck. It happens. Getting directions to BWI airport isn't just about plugging a destination into a GPS and hoping for the best; it’s about understanding the geography of a hub tucked perfectly—or awkwardly, depending on who you ask—between Baltimore and D.C.
BWI sits about 9 miles south of downtown Baltimore and roughly 32 miles northeast of Washington, D.C. Because of that middle-child positioning, your experience varies wildly based on which direction you’re coming from.
Coming From the South: The D.C. and Northern Virginia Shuffle
If you are starting in Alexandria or D.C., you have choices. Most people instinctively jump on the Baltimore-Washington Parkway (MD-295). It's scenic. No trucks are allowed, which is a blessing. But it’s narrow. If there is a fender bender near the National Security Agency exit, you are basically stuck in a beautiful, tree-lined parking lot.
Usually, the directions to BWI airport from D.C. involve taking New York Avenue out of the city to hit the Parkway. Keep your eyes peeled for the I-195 East exit. That’s your golden ticket. I-195 is the dedicated spur that feeds directly into the airport terminal circuit. If you miss that exit, you’re headed toward Baltimore, and turning around on 295 is a nightmare.
Alternatively, you’ve got I-95 North. It’s wider and handles more volume, but you share it with massive semi-trucks. Take I-95 N to I-195 East (Exit 47). This is often the faster route during the "dead zones" of the day, but during rush hour, the merge at the Capital Beltway can add twenty minutes to your trip just like that.

Navigating from the North: Baltimore and Beyond
Coming from Baltimore is a breeze, relatively speaking. You’re basically just dropping down 295 South or I-95 South. From the Inner Harbor, it’s a straight shot. You take Russell Street, which turns into the BW Parkway, and look for—you guessed it—the I-195 exit.
People often overlook the I-895 (Harbor Tunnel Thruway) option. If I-95 is backed up near the stadium complex, 895 can be a lifesaver, though it costs a toll. It merges back into I-95 just south of the city, putting you right where you need to be to catch the airport spur.
The Secret Language of BWI Signage
Once you get onto I-195, the road opens up, but the signs get busy. BWI is structured in a giant loop.
- Upper Level: This is for departures. If you’re dropping someone off, stay in the left lanes as you approach the terminal.
- Lower Level: Arrivals and baggage claim. This is where the chaos lives. If you’re picking someone up, do not—I repeat, do not—linger at the curb. Maryland Transportation Authority (MDTA) police are famous for their "keep it moving" attitude. They will whistle at you. They might even yell. It’s nothing personal; they just have a lot of traffic to manage.
Parking: Where Do You Actually Go?
Looking for the Hourly Garage? It’s directly across from the terminal. You enter by following the "Hourly Parking" signs from the main loop. It’s expensive, but if you’re only there for an hour to meet someone at the gate (though you can't go through security without a ticket), it’s the most convenient.

The Daily Garage is a bit further out. You’ll see the entrance on Terminal Road and Scott Drive. There are frequent shuttles, but honestly, if you have the time, it’s a solid middle-ground option.
Then there are the Long Term Lots (A and B). These are the budget-friendly heroes of BWI. They are located off MD-162 (Aviation Boulevard). When you follow directions to BWI airport for long-term parking, you’re looking for New Ridge Road or Stoney Run Road. The shuttles run 24/7, but give yourself an extra 20 minutes. I’ve waited ten minutes for a bus before, and when you’re stressed about a flight, ten minutes feels like an hour.
Train Travel: The MARC and Amtrak Hack
Sometimes the best directions don't involve a steering wheel. BWI has its own rail station (BWI Marshall Rail Station).
If you're coming from Union Station in D.C. or Penn Station in Baltimore, the MARC Penn Line is incredibly cheap—usually under $10. Amtrak also stops there if you want a bit more comfort. Once you get off the train, there is a free shuttle that runs every few minutes to the terminal. It’s a 10-minute ride from the tracks to the ticket counter.

What Most People Get Wrong About the Cell Phone Lot
Don't be the person circling the terminal for 30 minutes. BWI has a great Cell Phone Lot. It’s located on Scott Drive, right next to the Daily Garage entrance. It’s free. You sit there, wait for the "I have my bags" text, and then it’s a two-minute drive to the arrivals curb. It saves everyone a headache.
Navigating the Terminal Construction
As of early 2026, BWI is still tweaking things. There has been significant work on the Connector between Concourses A and B. This doesn't change your driving directions, but it might change how long it takes to walk from the garage to your gate. Always check the airport’s official site or Twitter (X) feed for "Day-Of" alerts regarding road closures or lane shifts on the terminal loop.
Actionable Steps for a Smooth Arrival
- Check the MDTA Traffic Cams: Before you leave, look at the live feeds for I-95 and MD-295. If one is red, take the other.
- Aim for I-195: Regardless of your starting point, I-195 is the only way into the terminal. If your GPS tells you to take a back way through Dorsey Road, only do it if there’s a major accident on the highway.
- Use the "Arrivals" trick for "Departures": If the upper level is slammed with cars during a holiday rush, have your ride drop you off at the lower level (Arrivals). You can just take the elevator up. It’s often much emptier.
- Pin Your Parking: If you use the Long Term lots, take a photo of the bus stop number and your row. Those lots are massive, and finding a silver Honda in a sea of a thousand cars at 11 PM after a cross-country flight is a special kind of misery.
- EZ-Pass is Mandatory: Well, not literally, but if you take the tunnels (I-95 or I-895), you’ll want it. Pay-by-plate is more expensive and a hassle to deal with later.
BWI is generally one of the easier airports to access in the Northeast Corridor, provided you respect the rush hour windows (generally 7 AM – 9 AM and 3 PM – 7 PM). Outside of those times, it's a straightforward trek. Just keep your eyes on the signs for I-195, and you'll find your way just fine.
