Getting from Boston University to the Massachusetts Institute of Technology is a short trip across the Charles River, spanning roughly 1.6 to 2 miles depending on your exact starting point and destination buildings. Whether you're heading over for a cross-registration class, a research collaboration, or a weekend event, the journey takes anywhere from 5 minutes by car to 30 minutes on foot.
The two campuses sit facing each other across the water in the Greater Boston area, making inter-institutional travel quite straightforward. Multiple public transit options, rideshares, and pedestrian pathways connect the main BU campus to MIT’s Cambridge grounds, letting you choose a route based on your budget and schedule.
Walking and Biking Across the River
If the weather cooperates, walking is one of the most reliable ways to make the trip. The walk takes about 30 minutes if you cross via the Harvard Bridge or the BU Bridge, offering views of the Charles River Basin and the Boston skyline.
Biking or using local micro-mobility services cuts that travel time down significantly. A bicycle or shared scooter trip takes around 10 minutes.
- The BU Bridge Route: Best if you are starting near the western end of BU's campus. It drops you right near MIT's West Campus and the student residence halls.
- The Harvard Bridge Route: Ideal for travelers starting near central or eastern BU. Crossing via Massachusetts Avenue puts you right at 77 Massachusetts Ave, the main entrance of MIT.
- Bluebikes Sharing: Docking stations for Boston's bike-share system sit right outside both universities, making a one-way pedal cheap and easy without needing to lock up your own bike.

Public Transit via the MBTA
Public transit options run frequently, though taking a direct bus or combining a tram with a bus usually requires a bit of planning around schedules.
The MBTA operates local bus routes that bridge the river gap efficiently. For instance, the Line 47 or designated local buses connect transit nodes near Commonwealth Avenue straight toward Cambridge. Alternatively, you can hop on the MBTA Green Line from BU Central to a transfer point like Hynes Convention Center, then catch the #1 bus across the Harvard Bridge.
Total transit time usually ranges from 20 to 30 minutes, and fares remain low—typically costing just a few dollars using a CharlieCard or contactless payment.
- Bus Line 47 / CT2: Excellent connections from campus arteries toward Central Square and MIT's campus zones.
- Green Line to Route 1 Bus: A classic combination that drops you right on Massachusetts Avenue in Cambridge.
- Red Line Context: While MIT sits directly on the Red Line (Kendall/MIT station), getting there from BU's Green Line requires heading inbound toward Park Street or downtown to transfer, making buses or walking a faster choice for most direct trips.
Driving, Taxis, and Rideshares
When you're carrying heavy equipment or running late, a car or rideshare gets the job done fastest. A taxi or rideshare service takes about 4 to 6 minutes under normal traffic conditions, with fares generally landing between $7 and $12.
However, Boston traffic can be unpredictable. Peak rush hours around the Charles River bridges can double or triple driving times.
- Rideshare availability: Uber and Lyft operate continuously around both campuses.
- Parking restrictions: Visitor parking at MIT is strictly limited and mostly paid. If you drive, check ahead for campus garage rates or public lots near Kendall Square.

Choosing Your Best Option
Your ideal mode of travel depends on what you're carrying and how much time you have.
+--------------------+------------------+------------------+
| Mode | Estimated Time | Cost |
+--------------------+------------------+------------------+
| Walking | 30 minutes | Free |
| Biking | 10 minutes | Minimal/Pass |
| Bus / Transit | 20-30 minutes | ~$2.40 |
| Taxi / Rideshare | 4-6 minutes | $7 - $12 |
+--------------------+------------------+------------------+
If you travel this route daily for classes or research, buying a monthly MBTA pass or investing in a personal bicycle saves both money and time.
Frequently Asked Questions
Can I cross the river on foot safely during winter?
Yes, the sidewalks on both the Harvard Bridge and the BU Bridge are cleared of snow by city crews, but high winds off the water make warm layers essential during winter months.
Is there a direct shuttle between Boston University and MIT?
Neither university operates a dedicated inter-campus shuttle for general students. Everyone relies on public MBTA buses, walking, biking, or rideshares.
What is the absolute cheapest way to get across?
Walking is entirely free, while taking an MBTA bus or subway connection costs standard local transit fare, making public transit the cheapest motorized option.
How do cross-registration students usually commute?
Most students cross-registering between the two schools prefer biking in good weather or taking the bus, as parking at either campus is expensive and difficult to secure.
