With a highway share of 0%, you won't be dealing with the monotonous drone of an interstate; instead, you will be navigating a turn-heavy path that demands your full attention.

Trip Plan

To make the most of your 3-hour and 43-minute trip, try to depart during daylight hours to better navigate the turns on local streets. Since the route involves a significant number of turns, pacing is key; take advantage of your one planned stop to refuel and reset your focus. Keep your $32 fuel budget in mind when planning your itinerary to ensure you aren't caught off guard by local pump prices.

A concrete tip for this specific drive is to double-check your turn-by-turn navigation before leaving, as the reliance on local streets like Main Street requires more frequent course corrections than a standard highway route.

Holiday weekends tend to make both departure and arrival windows slower than the raw route time suggests.

Time zone

Same local time

Origin and destination are on the same clock, so arrival timing is easier to judge at a glance.

Temperature spread

11 degrees warmer at arrival

A meaningful temperature swing is a good cue to rethink layers, water, and how soon you want to arrive.
