As a FYI, there is a major construction project on 120 starting this summer and going through 2015. There will be delays on weekdays and non-holidays. This may or may not make a difference in travel plans from the West side.
Ouch! Thanks for posting.
Following is from NPS web site:
Delays Sunday night through Friday afternoon
11 pm to 6 am - 1 hour
6 am to 7:30 am - 15 minutes
7:30 am to 3:30 am - 30 minutes
3:30 pm to 4:30 pm - 15 minutes
4:30 pm to 11 pm - 30 minutes
Not sure if I will change my plans. 30 minutes is not toooooo bad:-(
