What is the current traffic situation on I-15 in Las Vegas? -

I will be traveling to Utah from LA between 12/21 and 12/20 (2009). It seems that there is always road construction along I-15 in Las Vegas causing a 1-2 hour delay in my drive time. Can anyone advise me on the current situation? Is it any better than last year when it took me 2 hours to go from Craig Rd to Russell Rd?

smooth sailing now it is better

I15 is still under construction and worse during rush hour.
