If you are not already working with an agent I would be pleased to meet with you- there are lots of great homes available in Mukilteo and what a great time to buy with favorable interest rates too! I would love the opportunity to earn your business! Susan
As others have mentioned, 164th can get busy during the rush hour commutes. That block is from about 6:00AM to 8:00AM and then coming into town at 3:30PM to about 6:30PM. As Courtney mentioned however, you would be driving a reverse commute. In the morning most people are driving to the freeway and in the evening most are driving into Mill Creek. I have driven this rout multiple times during the rush hour. While it is busy, the commute you would be making would not be bad at all. Even when driving the commute direction I have found it not to be over whelming as others may feel just use a little bit of patience and you will get through it with no problem.
Now that being said, you can also take 128th across. To get there from Mukilteo though you would come up Beverly Park all the way up to 112th and then turn southeast onto airport road which then becomes 128th.
If it were me though, since I have come that far north, my preferred route to cross over I-5 is to turn onto 112th and just stay East on it till I cross over I-5 and get to the Bothell-Everett Hwy. Then you go south from there and you will then be in Mill Creek. This route is certainly a lot less busy since there is no onramp from the freeway. They are completing some widening construction on 112th where it crosses over I-5 but I have found there to be little to no slowdown.
I hope this helps. Mukilteo is a great place to live. I would recommend that you don't let the commute be the deciding factor in living in Mukilteo. I have had the chance to work with many people in Mukilteo that love where they are at.
Lots of inventory in mukilteo area. Make sure you wheel and deal really hard. Good deals are to be had there!
Either way, though, if you are going to Mill Creek for work, it is sort of a reverse commute for you - you should be fine. It is the people living in Mill Creek trying to get to I-5 that have the issue... Let me know if you have other questions.
