Several roads across Los Angeles will be closed for the 40th LA Marathon, impacting traffic for many residents.

When the L.A. Marathon kicks off on Sunday, March 16, you’re going to want to avoid driving near some of the city’s busiest areas starting at 4 or 5am and until later in the morning or afternoon: Steer clear of Downtown until a little after 10am, avoid Hollywood (specifically near Hollywood Boulevard) until around noon and Beverly Hills until 1pm.
