BUFFALO, N.Y. — Buffalo police are investigating the cause of a deadly motorcycle crash early Thursday morning.

They say a man lost control of his motorcycle around 5 a.m. on the ramp from the I-190 north to eastbound Route 198.

The ramps connecting the two roads were closed for several hours while authorities reconstructed the crash scene.

The ramps have since reopened.

Police have not released the name of the victim.
