Parking is limited on Friday since classes are in session. If you need to park, there are residential areas near campus (not encouraged) and visitor pay lots (Euclid Autopark near UMC) on campus.

CU has a football game on Saturday, so parking is very limited and traffic will be a factor. Game time is 5:00pm so it should not interfere with morning arrivals. If you must drive, there are residential areas near campus (west of Broadway) for street parking. These residential zones should have plenty of parking if you arrive in the morning. Campus visitor pay lots (Euclid Autopark near UMC) on campus may not be available during a day-time game. Parking on campus costs $20 on football game days.
We have secured a parking lot very nearby with FREE parking for Saturday Bioneers attendees. This parking is limited and priority needs to go to presenters and exhibitors. If you must drive, please use Lot 264, located on the north side of University Ave on the east side of 15th St (outlined in red on the main campus parking map at E-5). You will need to get a parking pass from the registration booth. http://www.colorado.edu/parking/maps
Note that campus parking meters are enforced 7 days a week. The free parking will only be available in the above designated lots. Do not get ticketed!
