George Floyd protests shut down both of Manhattan’s major highways

Angry protests over the Minneapolis police killing of George Floyd shut down Manhattan’s two major highways for much of Saturday afternoon.

A northern stretch of the FDR Drive on the island’s east side was shut — first by some 150 protesters and then by the NYPD — after 2 p.m.

The protesters entered the drive on foot, at around W. 111th Street, blocking southbound, then northbound traffic.

Shaking fists in the air, and shouting “No justice, no peace,” and “Black lives matter,” they marched southbound through the traffic jam they created.

Cops on scooters and bicycles and on foot intercepted them at around 106 Street, directing most of the crowd off the highway and onto a parallel sidewalk.

Protesters who refused to leave the highway were plastic-cuffed to chants of “let them go.”

Meanwhile, at around 3 p.m., at least 100 protesters stormed the West Side Highway at 125th Street, sitting down en masse in the southbound lane.

They sat for a few minutes, blocking southbound traffic, as another 100 protesters poured over the nearby on-ramp and crossed the divider into the northbound lane, where they, too, sat down.

Hundreds more protesters steamed onto the highway — forming a group totaling about 1,000 people.

They began marching south between halted cars — some of whose passengers joined in the chants of “Black lives matter.” They all began marching south for a mile and a half to 95th street, where police broke up the protest.

A half-dozen who refused to leave the highway were arrested — including a woman who was knocked to the ground before being cuffed.
