Seasonal Notes
Summer travel usually means heavier construction, hotter rest stops, and busier weekend traffic around major cities.
Winter travel shortens daylight, so a route that looks manageable on paper can feel much longer after dark.
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
14 degrees cooler at arrival
A meaningful temperature swing is a good cue to rethink layers, water, and how soon you want to arrive.

Cheap food and beer abound in this true sports town and the locals are amazingly friendly. A city of about 303,000 (2021) in Allegheny County, at the center of a metro area of about 2.4 million in southwestern Pennsylvania, Pittsburgh is situated at the confluence of three rivers: the Monongahela and Allegheny Rivers, which meet to form the Ohio River. The city's unique terrain has resulted in an unusual city design and a hodge-podge of unique neighborhood "pockets" with diverse ethnic and architectural heritage.
