Like any big city, McKinney motorists usually spend a few more minutes during peak hours between 7:45 am to 9 am to between 4:15 pm to around 6:30 pm. If you cannot avoid traveling at peak hours, try to stay away from major intersections, entry points, and some roads are known to experience frequent traffic snarl-ups. Such route includes Rolling Hills, especially from North McDonald St to Cypress Hill Dr. and or from Trinity View Dr. to N McDonald St. Instead, use less congested roads such as Collins Blvd, Spring Valley Rd., Midpark Rd., and Belt Line Rd.
