The Department of Transportion is starting its work on field investigations into how to reduce the dangers of rock falls on the Seward Highway in the areas between mileposts 104 and 114.

The section is located between approximately Potter Valley and Indian Valley, which has been prone to rock slides in the past.

That means lane closures from Monday through Thursday as geotechnicians take a closer look at how to best proceed with rock slide mitigation. Some of the ideas include installing more draped mesh, rock bolts, dredging wider ditches, and scaling, which means preemptively removing rock that is likely to fall. The northbound lane, which abuts the cliff side will be closed as the geotechnic crews use bucket trucks, ladders--as well as dropping down in harnesses from above--to get a closer look at the rock face.

The DOT is advising folks to plan for extra time on their trip on that section of the road between June 17 and June 27, during weekdays. Fridays, Saturdays and Sundays will be open as usual.

Still, real work won’t be starting until next summer. It’s estimated to cost $10 to $20 million.
