How to Navigate Traffic in Casper, Wyoming: Peak Times and Best Routes
To navigate Casper efficiently, avoid the CY Avenue and Poplar Street corridors on weekdays between 7:15-8:45 AM and 4:30-6:00 PM, use 2nd Street or Collins Drive as alternates, prepare for significant winter delays from November to March, and be aware of active speed enforcement on major boulevards and in school zones where fines start at $120.

Bike & Pedestrian Routes
Casper is improving its non-motorized infrastructure, but careful route selection is vital for safety.
Safe & Recommended Routes:

- Downtown: Low-speed streets (David, Center) are generally safe for experienced cyclists.
Areas to Avoid on Bike: CY Avenue (US-20/26), SE Wyoming Boulevard (between CY and 12th), and Poplar Street north of 12th due to high traffic speeds (>45 mph) and narrow shoulders.
