This is a very long westbound drive—roughly 31–34 hours behind the wheel before stops—so it cannot be completed safely in one day. Leave Elizabethtown before dawn and drive to Hershey for breakfast at Hershey Pantry, where a substantial meal typically costs about $15–25 per person and takes around 45 minutes. Because you are traveling on a Wednesday, check the restaurant’s current opening time the evening before; an early start is important, but do not trade sleep for a few extra miles. From there, follow the planned no-toll routing via I-76, I-70, and I-64, watching for construction, winter weather, and state-specific restrictions on commercial-style navigation routes.
Continue west toward Norwich, Ohio, and take a 45–60 minute break at the National Road-Zane Grey Museum. This is a useful leg-stretching stop as well as a compact introduction to the historic National Road and local author Zane Grey. Seasonal hours can be limited in November, and museums in this area may close on certain weekdays, so verify the schedule before committing to the detour. Keep fuel stops flexible rather than waiting for the tank to get low, particularly across the less densely serviced stretches of eastern and central Ohio; the museum is best treated as a bonus stop, not a reason to push beyond safe driving limits.
Continue through I-70 toward St. Louis, then use I-29 and later I-90 as planned for the onward journey to Montana. If traffic and daylight permit, spend about an hour walking the grounds of Gateway Arch National Park and viewing the Arch from the riverside; the outdoor grounds are generally the easiest part to enjoy without a timed ticket, while tram and museum access may require advance booking and separate admission. For the night, reserve a well-reviewed hotel in or near St. Louis with guaranteed parking—downtown is convenient for the Arch but may charge more for parking, while airport or west-county hotels are often easier for a heavily loaded road-trip vehicle. Do not attempt to reach Big Timber tonight: continue west the following morning, with at least three or four total overnight stops planned for the full no-toll drive.
