Washington, DC to MontrealAbout 940 km door to door. I-95 or I-270 to I-81 north, then the I-87 Northway to Lacolle-Champlain. Loading in the District is scheduled around building and street access.
Baltimore to MontrealAbout 880 km, the shortest of the five. I-83 meets I-81 at Harrisburg, then the Northway to Lacolle-Champlain, so Baltimore pickups can be an early stop on a northbound truck.
Alexandria to MontrealAbout 950 km from Northern Virginia. The Beltway and I-66 feed I-81 in the Shenandoah Valley, then Pennsylvania and the Northway. Virginia pickups are sequenced with District loads.
Frederick to MontrealAbout 920 km. Frederick sits on I-70 and I-270, a short hop to I-81 at Hagerstown, so the truck is on its main northbound highway almost straight from the driveway.
Rockville to MontrealAbout 940 km. I-270 north to Frederick and I-70 west to I-81 at Hagerstown, then Pennsylvania, the Northway and Lacolle-Champlain. Suburban driveways tend to give a truck easier access.
