Here's the fun part of President Obama's visit to USC: We'll soon get to debate about which of his recent L.A. trips, his Westside appearance in August or his Trojan-campus campaign stop for Sen. Barbara Boxer at 1:30 p.m. Friday, tied up the most traffic.

Until then, we have the official LAPD list of street closures for you:

Martin Luther King Boulevard between South Figueroa Street and South Vermont Avenue:

Soft closure 9:30 a.m. to 11:25 a.m.

Hard closure 11:25 a.m. to 2:50 p.m.

Plus …

South Vermont Avenue between Martin Luther King Boulevard and Exposition Boulevard:

Soft closure 9:30 a.m. to 11:25 a.m.

Hard closure 11:25 a.m. to 2:50 p.m.

South Figueroa between Martin Luther King and 39th Street:

Soft closure 9:30 a.m. to 11:25 a.m.

Hard closure 11:25 a.m. to 2:50 p.m.

Exposition Boulevard between Vermont and Figueroa

Hard closure 11:25 a.m. to 2:50 p.m.

Additionally, hard closures for all of the above will happen from 2:25 p.m. to 2:50 p.m.

The enterprising young journalists at USC's Neon Tommy have already created an interactive map for your traffic-meltdown pleasure.

Have fun.
