President Barack Obama will be in NYC today to discuss reform on Wall Street. The president’s speech takes place at midday in New York’s Federal Hall. He’ll be back in Washington by late afternoon – but streets in Lower Manhattan will really feel the impact as mass transit will suffer from detours and delays because of the Commander in Chief’s visit:

– BM1, BM2, BM3 and BM4 buses will exit the Battery Tunnel at Trinity Place and Take Trinity Place to Church Street where the normal bus routes will resume.

– 57th St.-bound  X-1, X-10, X-17, X-27 and X-28 will travel via Church St., turn left on Church St. , turn left on Canal St., right on Hudson St. onto 8th Ave., right on 14th St., left on 6th Ave. where buses will resume their normal routes.

In addition, some subway entrances and exits will may be temporarily closed.

Most of the Financial District will be under heavy security from about 11 a.m. to 3p.m. (when the President expected to arrive and leave at Kennedy Airport). The FDR Drive will be subject to freezes in the Wall St./South Ferry area in both directions. Broadway will also be affected. If you must drive, please stick with the West Side Highway.
