We all knew that traffic around Mission Bay was going to be bad during events once the Chase Center opens next month. Now we're getting an idea how bad.

Anticipating holdups or even full gridlock during the 200 Warriors home games and special events per year, UCSF Medical Center has launched a website and email alert system for its patients and staff. The site includes a color-coded calendar that highlights high-traffic days — yellow for delays expected and red for even worse delays expected.

A glance at September — the Chase Center opens Sept. 6 — shows all but six days colored either yellow or red. Chance the Rapper is performing on the 14th, and Janet Jackson will be there on the 21st.

The Chase Center is about a block and an half from UCSF Medical Center at Mission Bay, at 1825 4th St.

People can sign up for alerts on the site here.
