Manhattan —

The MTA is promising improved bus service along 125th St., but vendors who eke out a living along Harlem’s main drag say the benefits are going to come at their expense.

“I’m not sure where I’m going to be able to park when the bus lanes come,” said Zenola Smalls, who drives from her Brooklyn home early each day to sell CDs at a sidewalk table on the corner of Frederick Douglass Blvd. she’s helmed for 32 years.
