Alaska tries new technique to avoid trenching

Posted: Wednesday, January 26, 2011

FAIRBANKS — Alaska road crews are trying a new construction technique to replace culverts that avoids digging trenches and tying up traffic.

The Fairbanks Daily News-Miner reports the Alaska Department of Transportation and Public Facilities is replacing culverts on the Parks Highway near Ester using the new method that drives pipe through the roadway embankment.

The new technique avoids delays for the 2,500 drivers who use that section of the highway every day, on average.

The entire project should be completed by June, to allow for slope cleanup and seeding. Construction cost is $3.4 million.
