Spenard sinkhole repairs underway

By  | 

ANCHORAGE (KTUU) - A sinkhole in Spenard is being repaired after crews with the Alaska Dept. of Transportation worked to replace a corroded section of a storm water drain.

The five-foot wide sinkhole appeared on Benson Boulevard near the intersection of Minnesota Drive on May 24.

Crews say the problems started when holes in a storm water pipe let in nearly 30 square-feet of sand and dirt. The material sitting on top then washed away to the ocean leaving the asphalt hanging over open air.

The road then dramatically gave way.

On Saturday, crews were busy removing the section of damaged storm water drain and installing a new one.

The excavation closed two lanes of Benson Boulevard near Lois Avenue and crews expected it to be finished in the next couple of days.

Officials with the Dept. of Transportation say they used a camera inserted into the drain to locate the problem.
