JCK,
I have not been on either that way recently.
But,
Both Google Maps as AAA will get you reasonable information about construction and such. You can use the Online Triptik function of AAA without being a member, but there is something that you can't do and I don't remember what that is....
If you go out I-80, you might see the I-80 truck stop. (Like you would have to try to miss it.) The real restaurant there is nice if you feel like it, but you may want to park the rig on the north side of the lot and wander over to the truck museum. Parking at the museum is limited.
You can get free ice water and 5¢ coffee at Wall Drug and there is a nice parking area at the north end of town, but it is just a huge tourist trap.
