Although not as big as the MetroPCS Dallas Marathon in December, the Rock 'n' Roll Dallas Half Marathon, taking place March 22, will still cause its fair share of traffic headaches for the unprepared, as more than 13,000 runners will take over streets in downtown and Uptown.

So if you don't want to get stuck looking at runners Sunday morning, it's best to avoid the following areas. Marathon organizers have even provided a handy Google map for those who are more visual, or you can print out a road closure grid here if you're less digitally inclined:
