If you're keeping track of freeway closures, here's another adjustment to your scorecard: A planned three-night shutdown of I-15 has been changed for a third time.

Wasatch Constructors now intends to close southbound I-15 (from I-80 to 3300 South) and northbound I-15 (between 4500 South and 2100 South) on Wednesday and Thursday nights from 10 p.m. to 6 a.m. both days.The closure, necessary so crews can erect steel girders above the freeway for the new 2700 South overpass, was originally scheduled for Jan. 2, 5 and 6, then was rescheduled for Jan. 6, 7 and 8, then changed to Jan. 8, 9 and 12, then rescheduled one last time for Jan. 7 and 8.

Brian Mauldwin, spokesman for Wasatch Constructors, said the original schedule was changed because the contractor was told there was a "construction blackout" during the holidays, presumably meaning the weekend after New Year's Day. The final change was made, he said, because the contractor decided it could complete the work in two nights instead of three.

That's the kind of last-minute, ever-changing scheduling motorists have tried to get used to but probably never will before the accelerated, design-as-you-go, 4 1/2-year reconstruction project is finished.
