The crash occurred 1:30 p.m. Monday when the motorcyclist appears to have lost control and crashed, said Kieran O'Leary, spokesman for the Westchester County Police.
The unidentified man was transported to Jacobi Medical Center in the Bronx with serious injuries, which appears non-life-threatening at this time, O'Leary said.
The left and center lanes of the westbound CCP remain closed as the department investigates the crash.
