PORTLAND, Ore. (KOIN) — Nearly two dozen streets around the Portland metro remain closed Friday morning as snow dumped on Wednesday has led to slick conditions.

The Portland Bureau of Transportation says 23 streets are closed to drivers as of 8:45 a.m.

Crews are apparently running into trouble clearing roads as PBOT says abandoned from Wednesday’s storm are still blocking some streets.

PBOT says 8,000 gallons of de-icer and 45 gallons of salt were laid out overnight.

Heading into another potential storm this weekend, Don Hamilton of the Oregon Department of Transportation said new procedures are in place.

“We need to make sure that when the precipitation starts that we stay ahead of it, that means that we get out there with all of our tools, with the salt with the sand with the plows and the de-icer and that we stay ahead of it,” Hamilton said.

Drivers are urged to stay at home, but if someone must drive Friday, officials urge them to pack traction devices and allow extra time for their commute.
