Will Super Bowl Blvd. Clog Midtown? Updated 11:28 a.m. Good morning on this still cold Wednesday. It's 14 degrees and there's nearly an inch of snow on the ground. Today is the opening of Super Bowl Boulevard, formerly known as Broadway. Through Sunday, 13 blocks of Broadway - from 47th to 34th Streets - will be closed to traffic and converted into a so-called fan zone. Will this affect your commute? Do you dare venture into Midtown? It turns out that the onslaught of pedestrians, rather than the closed street, might cause the biggest problems. Many drivers already avoid Broadway, parts of which have been blocked to cars since 2009, when pedestrian plazas opened at Times Square and Herald Square. But many thousands of people are expected to descend on the fan zone. As Seventh Avenue clogs, taxis and other savvy drivers may head over to Fifth and Ninth Avenues, creating delays. Today will also offer the usual Wednesday afternoon matinee shows in the theater district, further complicating matters. As for subways, everything should be fine, the transportation reporter for The Times, Matt Flegenheimer, told us. But the Broadway Line (N, Q, R) and the Sixth Avenue Line (B, D, F, M) could get busier than usual. "They all go to Herald Square, which is at the foot of the mayhem," Mr. Flegenheimer said. If you're thinking of setting foot there yourself, here's a guide. Here's what else you need to know for Wednesday.
