120m long concrete culvert - shrinkage reinforcement
(OP)
are these amounts 0.18 percent enough? Even if playing with construction sequencing, pour every other 15 m first then leave it shrink, and then pour the rest in few weeks, the shrinkage is still considerable and I am worried about the cracking... On the other way, as there is a creek running through trying to avoid movement joints. Thanks.

The fact that it is buried will help, and that should let you get away with only one EJ, but normally even 180 ft is a bit long.

What's the expansion joint for? The concrete in a culvert won't expand.

Depending on the use, I'd have increased the hor rfg a tad... maybe to .25% or .3%...
Thanks JAE... didn't know that the % was 0.2% thought it was 0.18...
