The Minnesota Department of Transportation is nearly finished rebuilding westbound Hwy. 5 near Minneapolis-St. Paul International Airport. All that’s left for crews to do is put down lane markings.

But to complete the work, “We need a temperature above 40,” said MnDOT spokesman David Aeikens.

Friday’s chilly forecast has delayed the reopening originally set for Saturday. The highway is not expected to reopen now until sometime next week, Aeikens said, when temps are expected to warm.

Elsewhere, drivers shouldn’t encounter anything too spooky over the Halloween weekend, just some lane reductions on key routes that could slow down trips.
