Moving to a new city means learning the best ways to get around—from understanding local traffic patterns to figuring out whether driving or public transit is the better option for your daily routine. Gaithersburg offers convenient transportation options for commuters: it has a MARC station, a bus network that connects straight into the Metro system, and direct highway access to both Washington, D.C. and Baltimore. None of that helps much on move-in week if you don’t know where to start, though.
This guide covers the best ways to get around Gaithersburg, from commuting and public transit to everyday travel.
TL;DR
Gaithersburg is well connected for a suburb: Ride On buses (now fare-free) link the city to the Shady Grove Metro Red Line station, MARC’s Brunswick Line has a stop in Olde Towne Gaithersburg for trips toward Washington or Frederick, and I-270 plus MD-355 handle most of the driving. For daily errands, several residential areas are within walking distance of grocery stores, restaurants, and parks — worth checking before you assume you’ll need a car for everything.
Commute Options at a Glance

1. Public Transit: Bus, Metro, and MARC
Montgomery County’s Ride On bus system runs more than 80 routes through the county, including several that serve downtown Gaithersburg directly. As of mid-2025, Ride On has eliminated fares, making it one of the more affordable ways to get to work, school, or the grocery store without a car.
For longer trips into D.C. or nearby suburbs, Ride On connects to the Shady Grove Metro Station, the western terminus of the Red Line. From there, it’s a direct ride to Rockville, Bethesda, Silver Spring, and downtown Washington without switching trains.
Gaithersburg also has its own stop on the MARC Brunswick Line, with the station located in Olde Towne Gaithersburg. Since MARC primarily operates on weekday commuter schedules rather than all-day service, it’s helpful to confirm that the timetable aligns with your work hours before relying on it as your primary commuting option.
2. Driving: The Roads You’ll Actually Use
If you’re commuting by car, three roads come up constantly:
- Interstate 270 is the main corridor connecting Gaithersburg to Rockville, Bethesda, and D.C. to the south, and Frederick to the north
- MD-355 (Frederick Avenue) the local arterial running parallel to I-270, useful for shorter trips within Gaithersburg and neighboring Rockville
- MD-200, the InterCounty Connector, links I-270 to I-95, cutting down travel time toward Laurel, College Park, and BWI
I-270 in particular is known for heavy rush-hour congestion, so if your work hours are flexible, shifting your commute even 30 minutes earlier or later can make a real difference.
3. Airports and Longer-Distance Travel
Baltimore-Washington International (BWI) is about a 45-minute drive via the InterCounty Connector, and an ICC shuttle bus also runs from a park-and-ride lot at I-270 and MD-124 for those who’d rather not drive and park. Washington Dulles (IAD) is a similar distance by car. For rail, Amtrak departs from Union Station in Washington, D.C., reachable via Metro or a MARC train that makes several Gaithersburg-area stops on weekdays.
4. Biking and Other Commuter Options
A car- and bus-free commute is realistic for some routes. Bicycle lockers are available at the parking garage in Olde Towne Gaithersburg, right next to the MARC station, which makes bike-to-train commuting a workable option for shorter distances.
Montgomery County’s Commuter Services program is worth a look too — it includes ride-matching for carpools and vanpools, and many employers in the D.C. area participate in commuter benefit programs that subsidize transit costs. It’s a five-minute setup that can meaningfully lower your monthly commuting cost.
5. Getting Around Locally: Walking to Daily Errands
Not every trip needs to involve a highway. Depending on where you land in Gaithersburg, a fair number of daily errands are walkable:
- Kentlands Market Square grocery stores, restaurants, and shops within a walkable town-center layout
- Downtown Crown and RIO Lakefront both mix retail and dining around pedestrian-friendly outdoor space
- Bohrer Park at Summit Hall Farm is a large recreational park with trails, an aquatic center, and sports fields
- Seneca Creek State Park is a short drive from most of the city, useful for hiking or a longer walk without leaving town
If proximity to one of these destinations is a priority, ask about the actual walking distance when touring a community. A neighborhood that’s technically “close” to a shopping center can still involve a 20-minute walk along roads with limited sidewalks.
6. A Few Practical Tips for New Residents
- Test your actual commute during rush hour before you sign a lease, not just the drive time on a map
- Check the MARC Brunswick Line schedule against your work hours; it’s a commuter schedule, not all-day service
- Look into your employer’s commuter benefits before assuming you’ll pay full price for transit or parking
- If you’re biking to the MARC station, check locker availability at the Olde Towne Gaithersburg garage ahead of time
- Keep a backup plan for I-270 an alternate route on MD-355 can help on the worst traffic days
