PORTLAND As snows melted across the region, state officials warned Monday that cleanup in the aftermath of the Portland Metro Area s four-day winter blast could take weeks.

Monday afternoon, as many main roads remained clear, snow plows were still out in force, according to the Oregon Department of Transportation.

Crews were out clearing snow from the shoulders of roads and looking to head off high water problems. Once that s done ODOT still has work to do. The state said it laid down 7,600 yards of sand on freeways and highways since snows began falling on Thursday afternoon. Now that the snow has stopped, ODOT s got pick the sand back up.

Sweeping cannot take place in heavy rains and the sweeping operation will not pick up all the sand in one pass, said Kimberly Dinwiddie of ODOT. This means sand will remain along the shoulders for at least a few weeks.

ODOT cautioned drivers to give bicyclists and pedestrians a little extra room on the shoulders while the sand remains.
