Ice crews have plowed a 25-mile stretch of the Middle Kuskokwim from Kalskag downstream towards Tuluksak.
The remaining stretch to Tuluksak will most likely be completed after Christmas.
Mad Max, the crew’s 52-year-old plow truck, broke down Wednesday one mile above Edward Wise’s fish camp, after plowing just a few hundred feet that morning.
The harmonic balancer tore a hole in the timing gear cover, and parts have been ordered.
The delay could prevent people from traveling to see friends and family during the holiday.
