Update: Wednesday, 1:55 p.m.

A series of road closures scheduled for this week on sections of the Seward Highway south of Anchorage have been canceled due to deteriorating weather conditions.

A different closure at mile 68.7 near Turnagain Pass is however expected through Wednesday and Thursday night in both north and southbound lanes to relieve flooding.

Original story: Tuesday, 1:14 p.m.:

A section of the Seward Highway south of Anchorage will be closed this week and next week, while crews work on establishing cross-drainage culverts in the area.

The Department of Transportation announced that, starting Wednesday, sections of the two-lane highway will be completely closed, with no detour routes around them, meaning drivers who come at the wrong time will have to turn around, or face up to nine hours of waiting.

The specific areas will be between milepost 84.6 and 86.1 of the Seward Highway, just south of Girdwood, and before the Portage and Whittier turn-off.

The days impacted include October 24, 25, 29, 30, and 31, as well as November 1. That's Wednesday and Thursday of this week, and every weekday next week, except for Friday.

The entire road will be closed between 8 p.m. and 5 a.m. the following morning.

"There's a possibility that crews will break for 30 minutes in the middle of that time frame, and cars can go through then, but it's not guaranteed by any means," said Jill Reese, spokesperson with DOT. "Do not count on that."

Reese said crews will be working on the routes to make cross-drainage culverts for nearby creek and stream flow.

Aside from emergencies and official vehicles, no one will be allowed through during the construction hours, prompting DOT to recommend drivers avoid it, or make alternative plans.

"If you don't have to travel the highway during those times this week, stay home," Reese said.
