GREENBURGH - A ramp from the southbound state Thruway to the northbound Saw Mill River Parkway that was closed Monday after a retaining wall collapsed could continue to be an issue for drivers for several days to several weeks, state officials say.

The state Department of Transportation said the collapse was near the portion of the Exit 8A ramp that passes over the Saw Mill River Parkway.

The ramp breaks off of the Thruway, passes over Route 119, then splits into two, giving drivers access to either Route 119 or the northbound parkway. Only the Saw Mill portion of the ramp is affected.

“We still have to determine what the issue is and come up with a solution,” said DOT spokeswoman Gina DiSarro late Monday afternoon. “We’re still assessing it and looking at things. It takes awhile.”

She called it a "really high traffic area."

Drivers are being detoured to Route 119, where they can take a left and get to a Saw Mill River Parkway on-ramp a few blocks to the east.

State police said Exit 8 from the Thruway was closed at 5:39 a.m. Monday after debris spilled onto the roadway.

“At this point we don’t anticipate it opening (soon)," DiSarro said. "We hope we can get it open within a couple weeks.”
