For those waiting for today’s sizable marathon-related road closures to clear up, Alert DC says that both the Key Bridge and streets in Georgetown have reopened to traffic. The 14th Street bridge remains closed, however. Other streets will be closed until later this afternoon, so tread lightly. Oh, and for those interested: John Mentzer, a 33-year-old Navy lieutenant commander and Muliye Gurme of Ethiopia won the men’s and women’s races, respectively, running over 26 miles in the time that it took me to decide what to eat for lunch today.
