Earthquake repairs continue on Mat-Su roads
Earthquake damage continues to impact roads around the Matanuska-Susitna Valley.
Within the next couple of weeks, Department of Transportation crews will be working on repairs to four sites: Old Matanuska Road near Mikey Court, Hyer northbound off ramp, Fairview Loop Road near Jackfish landing, and Fireweed frontage road by Loberg Lake.
"All the sites exhibited a similar failure," said Project Engineer Todd Smith. "We have longitudinal cracking along the shoulder of the road, we have some slope failures."
After the Nov. 30 7.0 earthquake, DOT staff identified nearly 160 areas of damage around Southcentral. Smith said about two dozen of those are in the Valley.
Staff have been monitoring each site for any changes that could cause further damage.
Smith said the department doesn't want to do any unnecessary repairs over the winter since each fix is temporary and will have to be redone over the summer.
He said the four problem areas in the Mat-Su Valley have progressively gotten worse with the recent freezing and thawing and the continued aftershocks. Crews need to make repairs before spring breakup.
"Our concern is as we go into spring thaw and we get water inside that embankment, that it will cause the embankment underneath the pavement to start to fail where we would lose a traveled lane," Smith said.
Smith said DOT will likely find even more damage as spring approaches and the melting snow reveals more cracks.
