Construction Zone on I-40 near Williams AZ

I'm planning gas stops for a trip on I-40 starting in New Mexico and ending in Las Vegas. There is a construction zone between Exit Numbers 156-161 near Williams, AZ. Per information online it appears the the lanes were cut down to one lane in each direction.

Has anyone traveled through this construction zone and can confirm if there is only one lane open in each direction? Also can you tell me if there is a traffic delay and estimate how long, in either miles or time, the delay is?

I appreciate your help! Thank you!

Construction zones like that are common everywhere, and out in a rural area like that I would expect delays to be minimal. If you are trying to calculate to the minute, add 15 minutes to be safe. Don't worry about it, AZDOT doesn't list it as a high impact lane closure.
