Harbor Tunnel Lane Closures and MARC Schedule Shifts to Impact Thursday Commute

Overview of the Morning Commute
Commuters in the Baltimore metro area should prepare for a mix of scheduled maintenance and ongoing infrastructure projects this Thursday, March 5, 2026. While the morning rush is expected to follow typical congestion patterns, specific alerts on the I-895 Harbor Tunnel and the MARC Penn Line will require extra planning. Current weather conditions are cloudy with temperatures near 44°F and a slight 25% chance of rain, which may lead to damp road surfaces and reduced visibility during peak travel hours.
Major Arteries and Roadwork
The most significant impact today involves the I-895 Baltimore Harbor Tunnel. The Maryland Transportation Authority (MDTA) has scheduled maintenance that will culminate in the closure of the northbound tunnel bore tonight starting at 9:00 p.m. While this is an overnight closure, two-way traffic operations will be implemented in the southbound tunnel, which can lead to early evening backups. Motorists should expect delays of 15 to 20 minutes if traveling through the tunnel after the work begins.
On the I-695 Baltimore Beltway, construction continues in the Towson and Parkville areas. Drivers between MD 43 (White Marsh Boulevard) and Lillian Holt Drive should look out for off-peak, single-left-lane closures on both the inner and outer loops between 9:00 a.m. and 3:00 p.m. A reduced work zone speed limit of 45 mph is strictly enforced in these sections to protect road crews.
Additionally, a fatal pedestrian-involved crash was reported early this morning near BWI at the intersection of Aviation Boulevard and Amtrak Way. While the scene has likely been cleared, commuters in the immediate vicinity should remain alert for any lingering police presence or localized delays during the early morning hours.
Public Transportation Alerts
MTA Maryland and MARC riders are advised of several service modifications active today:
- MARC Penn Line: An interim schedule remains in effect due to regional Amtrak trackwork. Notable changes include Train 511 departing Perryville five minutes later than its standard time, and Train 421 departing Penn Station ten minutes later. Train 634 is currently skipping the West Baltimore stop; this service is not expected to be restored until mid-March.
- Light RailLink: Passengers should anticipate minor delays throughout the day as trains continue to operate at reduced speeds for safety inspections.
- Metro SubwayLink: All stations are now fully equipped with new CharmPass QR code scanners at the fare gates, streamlining the entry process for mobile app users.
Commuter Recommendations
To avoid the heaviest congestion, travelers are encouraged to use the I-95 Fort McHenry Tunnel as an alternative to the Harbor Tunnel during the transition to overnight work. For those using rail services, checking the MARC interim timetable PDF is essential, as several departure times have shifted by 5 to 10 minutes from the previous spring schedule.
