During working hours tram 22 runs 10 times per hour and after that every 15 minutes until 22:00. Tram 22 does not run on weekends and late evenings after 22:00, just like bus line 12 in the current situation. You can plan your trip on the website of transport company U-OV. Travelers to and from Utrecht Science Park and the P+R can use the frequent bus line 28 during the weekend, which connects these important destinations directly with Utrecht Central and the city center.
The number of trams will be increased in the course of 2020 to 12 trams per hour per direction.
