An NYPD investigation on the lower level of the Manhattan bridge is causing major subway disruptions for riders trying to get between Brooklyn and the city Thursday.
The MTA said around 7:40 a.m. that southbound B trains were running on the F line from West Fourth Street to Second Avenue, then terminating, and southbound D trains were running on the F from West Fourth to Coney Island.
Northbound B and D trains were running on the Q line from Dekalb to 96th Street, and some northbound B trains weren't going beyond Prospect Park.
Service had resumed by about 8:15 a.m., but lingering delays were expected on the B, D, F, M and Q lines.
